Has anyone tried these?

I emailed BUB and asked if they would have these new mufflers at their display in Sturgis. They responded that these mufflers didn't get on the truck headed to Sturgis. Unreal!! You have a new product and are sending a truck to an event where there will be hundreds of thousands of bikers and you didn't put them on the truck? Who the hell is in charge of their marketing?

Hopefully someone will get a set and give a report.

i saw those pipes on their website and wondered if they will flow any better than my stock ones with something like the 1.75" fulsac baffle?

DakotaZeb · « **Reply #3 on:** July 29, 2009, 12:31:43 PM »

I'm using the Fullsac 1.75" baffles right now but would still prefer something a little quiter.

1jeep · « **Reply #4 on:** July 29, 2009, 12:35:08 PM »

are they that much louder over stock? Currently my bike is stock, but once i get it back from the dealer i plan to remove the cat and chnage pipes, my first thought was the 1.75 fulsac

DakotaZeb · « **Reply #5 on:** July 29, 2009, 12:43:46 PM »

I've tried both the 2" and the 1.75" on my '03 SERK. At least in my opinion the 1.75" are much louder than stock. Not obnoxious, but definately quite a bit louder than stock. But everyone's hearing is different and it seems each bike is different.

I sure would like to hear a set of the BUB FL Stealth mufflers but with them meeting the EPA 80 db limit I wonder if they are any louder than stock mufflers. I'm sure they sound better even if they aren't much louder.

Zeb,

I am running the stock CVO 3.5" mufflers that came on our bikes with V&H true dual head pipes and couldn't be happier with the sound (or lack of). A little noise on acceleration and is quiet once you achieve a steady cruising speed.

Boatman,

I've had the stock mufflers for my '03 SERK on and off. I don't particularily care for the sound but could live with it. But I'd prefer something between the stockers and the Fullsac 1.75". That's why I thought that maybe, just maybe, the BUB stealth mufflers would fit the bill.

The other problem I have with my stockers is that the chrome is getting really bad on the end caps and I can't find any replacements. I could buy another set of pre-2006 CVO mufflers but before I go to that expense I'd really like to know what these BUB Stealth's sound like. Over the years I've tried nearly every muffler out there looking for that perfect sound. The search is still on!

I have a response posted under baffles. I installed them on my 2006 fatboy. I'm running Rhinehart staggered with the stealth baffle. I took out the competion baffle as they call them, and installed the stealth baffles right before i had the S/E super tuner installed and dyno tuned. I was trying to create more back pressure and a little less noise. The big difference I would have to say is at idle they seem to be alot let noisy. But still sound really good when accelarating.

DakotaZeb · « **Reply #9 on:** July 29, 2009, 02:40:56 PM »

Sorry, CVOBud, but we are talking about the new BUB FL Stealth Mufflers on this post, not the stealth baffles. Not sure what the correlation would be between the two.

1jeep · « **Reply #10 on:** July 29, 2009, 02:45:53 PM »

i am waiting to hear about these pipes, i like my bike being semi quiet, also like the epa stamp. In Ma. the bike laws are getting tougher and soon they will be checking everyones bikes, i dont need to be ticketed for being slightly loud. That was why i have been looking at keeping my cvo mufflers and doing the fulsac. On my 06 Street glide i went through 4 sets of pipes before stopping at the V&H monster ovals, even those could be a tad loud after 500 mile days.

DakotaZeb · « **Reply #11 on:** August 06, 2009, 02:34:57 PM »

Okay guys, I took one for the team and ordered a set of these BUB 7 Stealth Mufflers. Sounds like I should have them in about a week. Sure hope they are what I'm looking for. My wife thinks I've totally lost it when it comes to mufflers. Fortunately she is understanding as I proceed with my quest for the "perfect muffler".

I'll report back once I have them and have had a chance to test them.

They are due to arrive this Wednesday via UPS. I bought them from Phat Performance Parts for $491. http://www.phatperformanceparts.com/

I hope this is "the end". If I don't like them I'm going to stick with the Fullsacs and be done with it. I think!!

Zeb,
I talked to a tech guy at Bub yesterday and the mufflers are 80 db at idle,91db at 2500 RPM,they are a see thru design, 4" dia. with a much different baffle then the standard Bub 7 mufflers. Every see thru design muffler I have tried has been too loud for me including the 1.75 fullsac baffle in the CVO mufflers.

DakotaZeb · « **Reply #19 on:** August 18, 2009, 12:49:23 PM »

I will let you know in a few days. Mine will be here tomorrow. I really don't believe the 91 db. They never indicated that to me when I talked to them. That would make them as loud as the standard BUB 7's. Guess I'll find out.

bob2002 · « **Reply #20 on:** August 18, 2009, 02:08:08 PM »

I thought that was high too,when the monster ovals came out a V&H's tech told me they were 93db at a 50 MPH drive by,I can believe that after owning a set for a short time.

DakotaZeb · « **Reply #21 on:** August 19, 2009, 08:20:07 PM »

The BUB 7 Stealth mufflers arrived about 5:30 this evening. I installed them and went for a short ride as the rain was starting to move in. Can't wait to get out and give them a good test. Here's my first impression: I think they are about as close to perfect as I'm going to find. Nice low rumble without any loud bark even when you crack the throttle. Defintely louder than stock and a much, much better sound. And they are quite a bit quieter than the CVO/Fullsac 1.75" I just took off.

All you guys that are looking for something a little louder than stock but not too loud, I think these are the answer. And believe me I've tried a bunch. Two different sets of Screamin Eagle Performance mufflers, then Hookers, Rush, V&H Ovals, V&H Monster Ovals, Fullsac 2.0" and the latest 1.75". These Bub Stealths are also quieter than the V&H Monsters and have as nice a sound.

And bob2002, I don't know who told you that these are a see thru design. They certainly are not. They have a different, weird looking baffle.

I'll take some pictures and post them tomorrow when this weather clears up. But for the time being I'm a "happy camper". Of course time on the bike will be the true test. I'm probably one of the first guys in the country to have these mufflers on a bike.

And they look really good!

bob2002 · « **Reply #22 on:** August 19, 2009, 11:42:20 PM »

Thanks for the report Dakota. They're definately the best looking exhaust out there.

Personally, if I could keep the stock quiet (although I don't care for the tone) and get more performance out of them, that's what I'd do. So, to get the performance bump that I'm looking for (just a bit more), it looks like these Stealth are what I'm wanting. Thanks again DZ!

DakotaZeb · « **Reply #31 on:** August 20, 2009, 12:31:20 PM »

If you are concerned about dyno numbers it would be my guess that these mufflers aren't what you are looking for. However, if big numbers aren't your objective and you want a nice mellow sounding bike that is louder than stock then they could very well work for you.

In answer to a couple questions:

I Monster Ovals low droan on a long trip wore on me and I didn't like it.

The BUB Stealths can be bought for around $500, so no they are not pricey.

On a 96" the Stealths should be quiter than they are on my 103".

Okay, I've had the Stealths on now for several days and finally got out on a 100+ mile ride today. I'm still very happy with the Stealths. Great tone and sound. And I think they are actually a little louder than I thought in my first impression. Maybe fairly close to the Fullsac 1.75" but a better sound. If stock mufflers were a 1 and the loudess mufflers a 10. I would say the Fullsac 1.75" are a 3-4 and the Stealths a 2-3. But as you know, sound is very subjective.

The other day I had a buddy ride my bike so I could hear it as he pulled away and then made several passes by me on the street. The bike sounded fantastic.

Happy for now. I'll let you know if that changes for any reason.

bob2002 · « **Reply #43 on:** August 26, 2009, 10:34:28 AM »

Zeb,
I have about 500 miles on my mufflers now and they did get louder to the the point I'm going to reverse the tips to see if that helps if not I don't think I'll stay with them.We are going to the Finger lakes in NY this weekend it should make my mind up.I should have just stayed with my HD Touring/103 CVO mufflers. Have yours gotten any louder?

DakotaZeb · « **Reply #44 on:** August 26, 2009, 10:57:46 AM »

bob2002,

You and I are on the same page. I also think the Stealths have gotten louder with a little use. I only have a few hundred miles on mine but everytime I get on the bike I think they are louder. Still a nice sound and certainly not obnoxiously loud. However, I almost think the sound that bothers me is very similar to the same low droaning sound that the V&H Monsters made. I think at cruise the sound is much like the Monsters. Overall I like the sound, just not sure if I can live with it for the long haul. A buddy and I are taking a trip to Colorado the middle of September that will be about 1,800 miles. I'll sure know when I get back from that trip. Maybe I better hold on to the CVO/Fullsac's until after the trip.

This really upsets me because when I first put the Stealths on and started her up I truly thought I had found the idea muffler. Now I'm having second thoughts.

I too had thought about reversing the mufflers so they are slash down to see if that makes any difference. Please let me know what, if any, effect it has by reversing them.

OK boys here is one more for the mix!!! Anybody tried and have an oppinion on the Cycle Shack SE CVO Performance Baffles Pt # 1544? I just had a pair installed, I didn't care for the wide open flow through designed of the Fullsac although most seem to be happy with them. I was looking for something with a little more restriction for more torque and low to mid, Deep but not Loud!! I only have about 100 miles on them, no tuning device yet but will probably go with the SE tuner or Techno Research Direct Link. Right now I can say I'm not the loudest bike on the block but definitely not the quietest either I road with a 95 Inch stage 2 with SE performance heads and 211 cams and Vance & Hines 2 into 2 headers and Vance & Hines Classic Slip Ons and he was definitely a lot louder than the Cycle Shack 1544"s and yes the 1544's do have a Deep Low Rumble at idle BOSSTNBOY "DH"

This was the reply

Hello Bob,
It may well be that by changing the orientation of the outlet of the muffler that it may seem quieter than with the outlet facing up. While packing is utilized in the Stealth mufflers; it is designed for much higher mileage numbers that what you have put on your bike to date.

Thank You,

I also sent an email to BUB so we will see what response I get. Obviously, the response you got was not very encouraging. Maybe if they start receiving more they will do something. I questioned their R&D and told them that while the Stealths may have been EPA compliant when I installed they I don't think they would pass now.

Wow, not very encouraging to hear some of this. I was on the fence about pipes and ended up going with the v&h monster ovals and power dual head pipe. I had the monsters on my 06 street glide which was a 95", i fond them to be acceptable in the noise level department even after a 500 mile day. Funny thing on my ultra they seem a lot louder, possibly the head pipe?

ANyway i hope bub helps you guys out on this, i ran one of their pipes on my old VTX and it was a good product for the money.

DakotaZeb · « **Reply #56 on:** August 28, 2009, 01:30:39 PM »

Here's the email I just received from BUB. They sure appear to be a standup company.

George,

Thank you for your email on your BUB 7 Stealth mufflers. I want to ensure you that you have indeed found the perfect mufflers. The increased sound that you are experiencing is the result of a manufacturing issue with one of the components of the baffle. This problem was caught after the first 30 mufflers were manufactured and has been corrected. Additionally measures have been put in place to make sure this problem does not happen again. At this point only a few baffles have had issues, so this may be isolated to a handful of mufflers or systems. BUB Enterprises strives to design and manufacture products that meet the toughest quality standard which is what we would expect as a customer.

Brad Williams will contact you and we will replace your mufflers without question. Please post the contents of this email on the forums you belong to so that anyone with a similar problem is fully aware that BUB stands behind our products. The contacts are as follows: Warranty- (877)282-7473 or linnea@bub.com, Tech Support (800)934-9739 option 2 or bubtech@bub.com.

I would like to address your question about our research and development of the mufflers and give some general background on sound requirements. From reading the forums I see there is misinformation out there. The requirement to meet 80 dB(A) for sound is a US EPA federal standard which requires the use of a drive by test. You can’t say for example that driving at 50 mph down the road or while at 2500 RPM’s on a stationary test, being under 80 dB(A) you meet the federal standard. Even as one person wrote on a V twin forum, you can only use SAE J2825 as a reference to the EPA standard since this standard might “eventually be the standard by which we are judged”. BUB agrees completely that the stationary test that SAE has established makes the most sense for manufactures, consumers, and enforcement officials. As it stands now and since the 70’s, the current EPA drive by test is the standard that is to be used and this is the procedure BUB used in the development of our Stealth mufflers.

The design of our Stealth mufflers was not an easy task. The configuration is such that BUB used a mechanical baffle with multiple technologies that reduces the sound level without killing the performance. This mechanical baffle is wrapped in automotive grade muffler packing that is designed to last in sealed automotive mufflers for 100’s of thousands of miles. All of this is packaged in a high volume muffler to provide the sound level BUB must meet with a tone that is far superior to stock or anything else on the market.

As a manufacturer, BUB is required to meet an “acoustical assurance” period of 4,000 miles. All this means is that the mufflers must be under 80 dB(A) for this 4,000 mile period. To ensure we exceed this requirement BUB went to the lengths of sending a set of mufflers on a trip to Alaska for a total of 15,000 miles and then verifying the results of our previous sound tests. This test along with the many other sound tests in the development of these systems showed no discernable differences after mileage accumulation.

From the above I hope that you see BUB has done its homework on these mufflers. We have gone to great lengths to ensure our products are exceptional and meet all requirements we say they do. I should also mention that the BUB 7 Stealth FL mufflers are just the start of things to come from BUB. BUB’s R&D department is currently working on 7 Stealth mufflers for ST, Dyna, and Sportster applications. BUB is also going to package the Stealth FL mufflers with our brand new 09 FL TDX system (aka True Dual Crossover). The Stealth mufflers packaged with the TDX headers provide the most powerful product we currently have in our FL lineup and meet the EPA sound requirements.

After viewing the information you post on many forums, it is apparent that you are dedicated to the V Twin community. I hope you post this so that others can hopefully benefit from the information given here.

P.S. I have sent this same letter to the person I believe is bob2002.

I just got my stealth baffles and put them in yesterday. Only problem I had was that they wouldn't fit! IDK if they don't make them for the slip-on 7's, but these stated 7TD stealth baffles on box and packing slip. So I had to bring them down the road to a muffler shop and put the baffle in a tailpipe expander. After the stretch I got em to slide on and put em back on bike. I love the sound. The youtube clip on their website doesn't do it any justice.

Pete,

Sorry but this thread isn't about the BUB Stealth baffles. It's about the new 4" BUB 7 Stealth mufflers that BUB has just introduced. Not sure if you knew that. If you have a question about the baffles you might want to start a new thread.

DakotaZeb · « **Reply #62 on:** September 02, 2009, 07:54:48 PM »

My replacement mufflers should be here Friday. I am then leaving Sept. 12th for a week long trip (1,800+ miles) to Colorado. When I get back I'm assuming that I will have an opinion on whether they fixed the problem.

bob2002 also has a replacement set on the way. He's actually thinking about selling his.

Another side issue has also come up with the mufflers. I installed them in the "slash up" position and the inside of the end caps has started to discolor. bob 2002 has seen the same thing. I've asked BUB about the discoloration and they claim they shouldn't do it and that it's probably just a film from the combustion. But I've cleaned them with everything I have and the discoloration is still there. Think I'll install the new ones "slash down" so it's not so noticable. I wonder if anyone with the standard BUB 7's has had this problem???

Well, now I have something you're talking about. Yes my 7's are discolored. I've done the mild soap and water that bub talks about to clean them, but that doesn't work so well. I've since used brake cleaner to remove all residue and there is a discoloration. I put a coat of wax on after, but you still definitely see it. I'd say just leave it and the exhaust will even them out with carbon and whatnot, but if you don't regularly clean them they start to bubble up. Now that mine are I just leave em be and only clean the outside. Too expensive to replace for that. When the outside starts flakin, I'll look into havin them replated or have a friend powdercoat them black. Just sucks that you spend so much and after a lil over a year the chrome pops up. Same thing is happenin to HD parts on the bike tho too. $:-\$

I have installed mine in the slash down position because I like the look so much better. I have only put 60 miles on this new set and was able to polish out the residue this time,the jury is still out on me keeping or selling them.

Hi Guys,

I just got back from my Colorado trip yesterday and we logged nearly 2,000 miles. I drove in all types of conditions. From sunny and mid 80's to rain and hail and temps in the 30's. From 1,300 feet above sea level here at home to over 12,000 feet going over Independence Pass. Mountain curves where speeds were down to 10 mph to the interstate where we ran 80-85. I have to give the BUB 7 Stealths a big thumbs up.

The Stealths did not both me at all. Oh yes, there is a hum at cruising speeds but nothing like the what bothered be at highway speeds when I had the V&H Monsters. The Stealths have a nice low rumble with no raspiness or bark when you get on the throttle. I'm back to my original opinion that these are the best alternative to stock mufflers. Quieter than the Fullsac 1.75". If these are too loud I think you better to stick to the stockers. (Sorry BOB!) But then, as we all know, sound is very subjective. We all hear differently and I have hearing loss in some frequencies. But of approx. a dozen mufflers I've had on two different 103" bikes I like these the best. I need to get the bike cleaned up as it's a mess so I can see if there is any discoloring of the end caps.

Hope this helps some of you guys out. But remember, it is just my individual opinion.

Zeb

But your opinion is important.............to you!

No, seriously Zeb........I think mine and your goals on exhaust are the same. And while I've been the experiment in other areas of the bike (my friends were teasing me about opening up a seat shop before I finally tried a Corbin and quit buying after that), I've let you be the experiment with the "quiet" exhaust. Bub sent me another email a few days ago saying that the new exhaust for the 10s will be out late Oct. I'm waiting for the 10 Stealth exhaust.

By the way, thanks a bunch for the update.

bob2002 · « **Reply #71 on:** September 19, 2009, 11:38:32 AM »

Zeb,
Glad you had a good trip and your happy with the mufflers.I like the way they sound now more then before since I had the Andrews 21 cams and the V&H Power Duals installed. The wife is okay with them but rather have the SE touring mufflers so you know where that leaves me.

DakotaZeb · « **Reply #72 on:** September 20, 2009, 02:47:17 PM »

I got the bike cleaned up yesterday after my trip and see very little discoloration of the end caps. I have them installed "slash down" and would recommend this position to anyone buying these mufflers. With the "slash up" it's just harder to keep the inside of the end cap clean.

By the way, my Fullsac 1.75" are for sale again now that I've decided to keep the Stealths.

Well after talking with Zeb I went ahead and bought a set of the Stealths. I got them today and immediately put them on.

My impressions so far are:

They are a lot quieter than my monster ovals that I have had on for over 6000 miles.

They have a low sound to them similar to the monsters, but on the freeway they are a lot more enjoyable for me.

I can't tell any loss of performance vs. the monsters. I am running the PCV with auto tune module with a fuel moto base map.

The Monsters are probably a meaner or manlier sound, but I guess I am tired of them.

Overall they seem to be exactly what I was looking for, not a stock sound, but a nice deep sound and no drone when going 70 mph plus. That was my biggest reason I wanted something quieter. Up to 70 or so the monsters were ok, but when you are in the throttle they seem to bother me on longer 150 mile plus rides.

I haven't rode with them too much, but enought to know they are quieter in every aspect.

I am running a stock 110" with V and H true duals.

Have been looking at the exhaust your running. Talked to a tech at BUB the other day and he stated that the new TDX header pipe they make and the stealth mufflers will out perform, or have better numbers than the TD setup. am curious if anyone here has seen this, in their experiances with exhaust?
I no longer have the 07 CVO but i do have the new 2010 LTD and am looking at differant exhaust systems for it. like a lot of people i am not into the loud noise systems.

brassspike · « **Reply #82 on:** November 06, 2009, 07:58:36 PM »

Got mine on last night. Fit and finish look pretty good. Sound is quieter that the 1.75 sacks. No more crack when hitting the throttle. I didn't care for that and packed the cans. That didn't help. That's why I am trying the stealths. Sound is down lower but not too quiet. I have only run it in the garage so I cannot give the thumbs up or down yet. I might be able to get it out and under some "load" tomorrow. In our case the bsr likes it loud but I like it more on the mellow side. Might have to go back to the sacks if the boss is not impressed!!!

am curious about the hp and tq in comparison to the TDX or even the true duls system both with the regular Bub 7 mufflers!!

brassspike · « **Reply #84 on:** November 07, 2009, 03:10:18 PM »

Well I got out with it today. Did about an hour of all types of riding. 08 SERK......Stop and go and one little 100 mph cruise to see if they would blue. "So far" here is my impression compared with the sacks.
Idle sound goes to BUB it really sounds better, low Harley sound
Light acceleration to BUB Low to mid rpm again nice low throaty sound
Heavy acceleration high rpm to sack high rpm sound is great!
Cruise to BUB nice tunes out the back!
6th gear cruise and acceleration definitely BUB! Nice Harley sound without all the drama!

I realize this is all subjective but "so far" I like the bubs for the bike and riding that I do. They are quiet. I think ZEB said his wife thought they were too loud. With all due respect, I can't imagine them being to loud unless they burn out quickly. Oh, and these things stink while they are breaking in.

I have some video with sound if I can figure out how to post it? I hope this helps someone as much as the other posters have helped me. Oh and they still have to pass the boss's sound test or to ebay they go!!!

While I do not have Stealth mufflers on mine, I perfer the BUB 7 TD. I recently switched from the D&D Fat Cat (2 - 1) to the BUBs. I lost no low end torque or horsepower vs the Rinehart TD which generally have a tq dip around 2000 thru 2500 rpm. JMO. Love the sound of either system

Thanks for the report. Just to be sure.....you have the Bub Stealth and not the Bub 7, correct?

Dakota Zeb has given positive feedback on the Stealth and if your report is on the Stealth then I believe this is the system that I'm wanting. Just tired of the obnoxiously loud exhaust systems. Ran the Thunderheader for way to many years and now am paying the price with my hearing when it comes to certain tones.
