Fullsac Performance · « **on:** February 10, 2009, 06:44:02 PM »

Heres a few pics I shot today while modifying a stock CVO headpipe.

Pic 1.
Headpipe VS bandsaw. Headpipe lost miserably revealing "power robbing obstruction".

Fullsac Performance · « **Reply #1 on:** February 10, 2009, 06:47:14 PM »

Pic 2

Obstruction VS air chissel.
Obstruction lost miserably revealing how the front cylinders headpipe is extended, bringing it much closer to face of the cat. There, I said it. Cat cat cat cat.

It's a wonder that there is any flow at all thru that pipe. It would be intresting to know how much pressure drop is across the cat.

The dyno says its about an 8 HP pressure drop.

Yes! And additional fuel (remapping) is required to take full advantage of the additional airflow.

Did you just use the pen mark to line up the pipe after the cut? Did you mig or tig it? I am pretty with a welder and am thinking about the same surgery on mine.

I draw a line with a sharpie on both sides before I cut. Makes lining it back up idiot proof. I Mig welded this one. The Tig would have a cosmetic advantage, but for what? Look at Harley's mig welds on both sides. It's all under the shields anyways. After the last pic, I sprayed the weld with a little Hi temp paint.

So the people here that have used the 1.6 core bit only remove the cat that is restricting the right side tail pipe? The cat is still restricting the left side due to it`s oval shape in the pipe, that the bit could not get. I this correct. Thank`s

Hey Steve i need some help. I changed out my baffle`s on my 09 serg to your 2,25`s, the sound is great. My friend has a stock 2009 ultra classic (Not screemin eagle) he is wanting to change out the baffle`s to your 2,25 also. I have not seen any how to`s on the stock ultra mufflers. At the end of the muffler it is an inverted cone shape,and it looks welded.
Any help from you or anyone who has done this would be great.

We finally got some warm weather and I had a chance to get the first two hundred miles on. After seeing these pics, I understand why there's a sluggish reaction to a quick twist of the throttle at low rpm. Thanks for showing us a clear view of the whole thing.

An exhaust guru I recently spoke with suggested that breathing in or coming in contact with residue from a cat can cause significant health problems. Not sure if that is true. But true or not it might be well worth it to wear some sort of protective mask while drilling and chisling a cat.

No heath hazzards in the cats. However a dust mask is a good idea.

I use to work in a plant that made Cats...

It is a ceramic material coated with platnuim, iridium and a third metel. The coating is very thin.

Mine is off my bike and I am about to cut, what did you use to cut?
The cat removal looks real clean, did you use the air chissel method, and last question did you tig weld it?
I have .045 cut-off wheel I am going to use and an air chissel but I will need to find someone to weld it.

I'm sure you would be better off finding someone that can use a bandsaw to cut the pipe instead of a cutoff wheel.
Probably the same shop you have do the weld can make the cut.

LarryB · « **Reply #41 on:** February 14, 2009, 05:48:10 PM »

I used a mil band saw, then hammer and chisel to remove the cat, clean it up with a narrow scraper.
Wear dust mask and gloves, and do it outside. if you can. I used a mig to weld it back.
hardest thing about all of it was getting the heat shields back on to fit well. they suc.
TN, I just used the same gaskets, they where in good shape.

TN · « **Reply #42 on:** February 14, 2009, 07:23:37 PM »

used a portaband to cut, very easy. a regular hole saw for the most removal, and chisel to clean. paid special attention to the weld zone. tig weld. painted with high temp silver.

gonna v-tune again.

guppytrash · « **Reply #43 on:** February 14, 2009, 09:57:23 PM »

Well, the cut-off wheel worked good, I used tape around the pipe as a guide. The wheel I used was as thin as a band saw. (4.5" X 045)

The air chissel worked great to gut it now I will be looking for a tig welder in my local area.

I currently have the SERT tuned to the base map of AC and Performance mufflers. Now I will probably need to get it dyno tuned when I get it back together.

Thanks again Steve for the info.

I think if your SERT map is a MP7, you can cut and paste the VE tables from my TTS map. Shoot me an Email and I will reply back with a copy of the map. Worth a try. Might save you $ome dyno time.

What affect on the warranty does this have? It seems it would be wise to find a head pipe from another bike just so you'd have the original one if you needed warranty work. Does anyone know how this affects it?

BryantH · « **Reply #56 on:** February 28, 2009, 08:06:39 AM »

RickC

Not at all - I have the cost posted on another thread. I'm paying $210 (I think that what I have on the other thread) and Jet Hot is coating my headers with their Extreme Silver coating - this coating is little different than ceramic. They coat in side and out - this helps with heat going through the header as oppose to through the surface (metal) of the header, which in turns hits the rider. I agree the cost is high but I got the header for low cost and since they are already off the bike, why not - Lord knows we pay enough loot for these bike. This price does not include shipping. I believe Jet Hot's cost for ceramic and their Sterling coating is a little less.

Hope this helps.

So far, there's only one person on here that I know of that has the Power Duals mounted...just a few days ago, and he also changed his cam in the process, so I don't think at this point we have any comparisons to go on. It sure doesn't look like there could be much of a difference between the unrestricted stock system and the Power Duals. I think someone at V&H got a little artsy and said, "Hey, we can make a fancy looking X with a heatshield since we're routing the pipes like Harley's stock system and we can call it a power chamber". But, yes, it would be nice to find out when someone gets a set mounted with everything else stock and the same set of mufflers and intake, and see where the numbers fall.

Honestly, I'm gonna be surprised if there is enough difference to justify the $500 price tag on performance alone. Especially when a patient person can find a stock, non-CVO header for half that price (or maybe less... much less...

) or the more industrious can just cut out the cat.

Now, I have to admit that I do like the way the Power Duals look. Big, fat honking headpipes (or heat shields, as the case may be); that big bold "X" (turn that sideways) on the right side of the bike; those are some sweet aesthetics!

So, maybe one can justify the price on a combination of performance and appearance...

Hey congrats on the new bike...I think I saw somewhere that you just picked up a new one a few weeks ago.

As far as the pipes go...a patient person can find a stock, non-CVO header...guess I'm not patient. Actually, this entire pipe experience has beat me up. I changed to the Fullsac's and drilled the converter, only to find there was more converter in there, then I ordered Power Duals which kept being backordered further and further, and then ordered the D&D Fat Cat and now I have found out that those are on backorder also. If I weren't so impatient, I may have been able to come up with a set of non-CVO pipes, but sending my pipes off to have them gutted was out of the question. It seemed worse to me to have the bike sitting there with no exhaust at all for any period of time. The lessons we learn or in my case, the lessons that I don't learn anything from. Why do I have a bad feeling that I'm not going to like all the racket from my D&D's and end up back to square one with the Fullsac's and either the Power Duals or gutted head pipes?

So...

1. Cancel the D&D Order

2. Either,

a. Contact every dealership in your area and ask them if they can lay hands on a non-CVO stock headpipe for you. Beg them. Tell them you'll be willing to pay $xxx.xx for it ($50? $100? $200? That's up to you); or

b. Park you bike *NOW*, pull the head pipes and send 'em to Steve at Fullsac. People are reporting pretty quick turn around...

3. Keep your FullSacs..

4. Ride the H-E-DOUBLE-HOCKEY-STICKS outta your bike.

5. Enjoy!

You'll be a few hundred dollars to the good... and... you might be done sooner...

Just my $0.02 worth...

P.S. BTW, I'm impatient, too. Usually I end up buying two or three or four different kinds of something for the bike before I decide what I really want to do. That gets expensive. I did that with my last two bikes. The only good news, is that I've got a chitload of parts in the garage to Ebay and help defray the cost of my CVO OCD (M-O-U-S-E!!!)... So, what I'm saying here, is that I know exactly how ya feel... now... and how you're likely to feel when you've got too much money invested in options that you aren't happy with and have to spend more money (or time or both) to get back to where you should have gone to begin with...

Hang in there!

a. Contact every dealership in your area and ask them if they can lay hands on a non-CVO stock headpipe for you. Beg them. Tell them you'll be willing to pay $xxx.xx for it ($50? $100? $200? That's up to you); or

b. Park you bike *NOW*, pull the head pipes and send 'em to Steve at Fullsac. People are reporting pretty quick turn around...

3. Keep your FullSacs..

4. Ride the H-E-DOUBLE-HOCKEY-STICKS outta your bike.

5. Enjoy!

You'll be a few hundred dollars to the good... and... you might be done sooner...

Just my $0.02 worth...

P.S. BTW, I'm impatient, too. Usually I end up buying two or three or four different kinds of something for the bike before I decide what I really want to do. That gets expensive. I did that with my last two bikes. The only good news, is that I've got a chitload of parts in the garage to Ebay and help defray the cost of my CVO OCD (M-O-U-S-E!!!)... So, what I'm saying here, is that I know exactly how ya feel... now... and how you're likely to feel when you've got too much money invested in options that you aren't happy with and have to spend more money (or time or both) to get back to where you should have gone to begin with...

Hang in there!

I already went through the dealership thing and only came up with one set of pipes and the guy wanted $350 for stock pipes. He did call me back and still wanted $200+ and I told him they can rot in the corner of his garage. I tried catching the dealers off guard by just asking first if they've been able to get pipes in and installed any on the 09's. Quick answer was always, "yeah, we've done lots of them". Then I hit them with the follow up question, and suddenly it was "well, let's see, I guess most of those I was thinking about were 08's and the only 09's we did just had slips ons installed". I got very little cooperation, other than my own dealer, who found me someone the same day, but I've already told you the outcome of that.

I really like the look of the D&D and I'm hoping that I can deal with the sound. My last bike had V&H Long Shot True Duals, and my friend had the D&D's on his SERK, and I thought my pipes were louder than his. I had no problem with the sound on the ones I had, but I think I was just getting used to the lower volume with the Fullsacs. I'll probably be happy with them...but if not, I'm sure I can find a buyer on here. Likewise, if I'm happy with the D&D, I'll probably be ready to sell the Fullsacs very soon.

So far, I've done pretty well with this bike. I've only put one part on that I took back off and bought something else. My friend offered to pay me full retail for the part less 20% that he figured he could get during a sale at a dealer. SOLD without hesitation there...I got 20% off when I bought it. My bike is at the dealer right now and it sure would be convenient if the pipes would arrive this week, but I haven't been able to get in touch with Eric at hdpipes.com to find out when they are shipping. I forgot to try him again today, but will tomorrow. I'll get this thing worked out one way or the other and then it may be time to pack my bags and head for TN. I think it's about time I get you and Larry to pull those bikes out of the garage and do some riding. Good weather is just around the corner.

I guess I have one question for the whole group here going with FullSacs, what performance numbers are you seeing. A local guy here did all the same as you all seem to be doing and it was disappointing to what gains it made. Did the cut and gut of the "material," welded back together and did FullSacs 2.25 and it only pulled 104 torque. That was after multiple dyno runs by a 10 yr vet on the dyno and done on different days, different times of day, etc. Not that that is disappointing but my 06 RG with 95 / heads / cams / etc pulled 99 torque. They then just threw on a set Kerker / PAT mufflers and baffles and it was pulling between 107 and 109 torque. Definately a difference.

Thanks, man! I picked her up about 2-1/2 weeks ago, then weather and a bad back have kept me to about 350 miles so far and no time to install the boxes of parts in my garage. I'll get there, though. Definitely...

Too late now. My D&D Fat Cat showed up here around 3:15pm. I took them out to the dealer and they took my old pipes off, packaged them up for me in the D&D box, and sent them home with me already. On the way home, they called to let me know the pipes were on and look great. I've got to leave it there until we get a little bit warmer day so they can dyno it now. New LED tour pack lamps/turm signals look great. NAV system needs a module, which is on backorder. Heated seat has a problem within the seat and it's on backorder also. So at least the few items I still need done will be a real quick fix when they are received and I should have my bike back the first nice day we get here.

Dyno numbers vary one dyno to the next, lots of tricks to make bigger numbers if that is going to satisfy the customer .
The numbers that got me....
Fullsacs less than $110, gut the cat $0 to $50...you can't beat those numbers with any aftermarket exhaust system.

That's why I did it, is it the absolute best? For me at about $150 total you betcha!!!

Let me know what they find out about your NAV. Did your nav ever work?

See 2 posts above yours. I didn't work. The tech showed me real quick how someone can tell if they have a bad module. If you take your outer fairing off, when you are facing the exposed back side of the stereo unit, look at the bottom left corner. There is a small (about the size of a pencil eraser head) colored sticker. Green sticker needs replaced. Purple sticker you are okay. They ordered me a new module and it's on backorder. They told me that the manufacturer is still working on making the module that actually works, which makes me wonder what the ones with the purple sticker are. If those work, why not put one of them in there?

The hell with trying to buy a stock 96" header pipe. People are not changing them and when they do they want mucho dinero. Took it off cut it in half and getting it welded tomorrow. The cat was very easy to remove. It was easier than drilling it out with the core bit. Hello free flow pipes! Let's Roll

If you're considering it, go for it.

I got a set of headers off a guy for free who put true duals on his UC. I installed them yesterday but didn't have time to change out the baffles, I have a set of fullsacs still in the box waiting for me. I was going to tackle the baffles today but it was so pretty out I had to ride. Maybe it's just wishful thinking, maybe it's real, one thing is for sure, I noticed a difference today especially with low speed throttle response. After about 50 miles or so I began to notice a throatier sound, even more noticable at end of ride , 225 miles. I'm not sure if I'm doing any damage running it without tuning it, I've read that it is set to run very lean. My plan is to install the baffles then take it to a nearby dealer for a SSERT and a dyno tune.

I've had my bike since 02/28 and hit 2,500 miles today - I've got to tell you, it's an incredible machine.

I had 2,500 miles in the first month. You gotta get out and ride a little.

Please pardon a couple of, well, newbie questions here...
I have an '09 SEFB. Bone stock.
I cannot bear the silence of the mufflers (Clariiiice...) and I see a chance here to reverse some power loss. I'm breaking it in stock so the stealership can't cry.
My questions are:
- My 110 gets hot fast, rode in 60F weather last weekend and sitting at a light for 10 seconds caused that engine heat management "lope". Cat cutout and baffles would mean a new tuner for sure, right? Or a new engine quickly with EPA map?
- Will the cat work cause one to fail at the emissions station?
- Lastly, can owners and users of the 2.25 baffles indicate how loud they really are? I've only been able to search out vids with smaller dia ones. The last scooter set off surrounding car alarms when started. Yeah, I'm one of them.

Any help is appreciated, a kick in the ass if I missed something obvious.

**** EDIT ****

Sorry for the resurrection, just realized this thread is six weeks old.

Highjagger · « **Reply #77 on:** January 27, 2010, 11:10:58 AM »

Tha CAT won`t cause a fail at the emission-test because they cannot really messure it .
They only check whether the CO2 is above 4.5 by volume
, and the CAT will worsen the number from stock about 0.95 to CATless maybe around 1.05 .
So , no panic about that .

jimcb1 · « **Reply #78 on:** January 27, 2010, 06:28:37 PM »

how cooler would a it run

Thanks for the response.
I was hoping that was the case; now the options have really opened up.

It sounds like your primary concern is running cooler and performance. Steve has posted a dyno sheet somewhere on here that shows the 2.25 baffle performing less HP and TQ than the other two. The 2.0 baffle performed best, with the 1.75 baffle a little less and the 2.25 baffle considerably less.

If you're just wanting to have an obnoxiously loud exhaust, go with Thunderheader.

I found a stock head pipe 09 FLH, Klock Werks 4" Revolvers, Dyno Jet Power Commander V, dyno tune. I lost my heat problem gained 15hp and 18 torque. Also have all stock parts ready to bolt back on.
