Title: SERG dual exhaust
Post by: gordy on August 09, 2009, 12:41:28 AM
Saw this bike in Sturgis last week and was wondering how much cooler it ran with the seperate pipes.  I gotta do something beside remove the lower fairing.

Rear pipe

Nice looking pipes.  What brand do you think they are?

I would think it would be a little hot for the BSR.

Fortunately my girl has a '09 Streetglide, so the first mod was to remove the rear footpegs and the second is to install the Corbin solo-solves that problem ;D  The pipes are from Freedom Performance in California.  I was hoping the fellow that had this done will reply.

 Just ceramic coat your stock catless header. Why trash power with a bogus "true Dual" concept. The merged exhaust of the stock header will make the most power. Separating the pipes will only give you more heat on the left side of the bike with 10% less power... :drink:

Appear to be Freedom's true duals. This is the same design they used forever on the left side. My wife says it is hotter on the 09 SERG than it ever was on the 05 SEEG with V&H True duals and S/E Pro Slip-ons. She has complained every time we ride that her rt leg gets hot, and I have ceramic coated headpipe w/o a cat, Fullsac wrapped baffles and TTS. Bike runs great, but her leg is hot to the touch. Guess she will get tougher over time.

Disappointing  :(!!  I was really hoping your mods would make a big difference in heat.

Hey Dracula, reread the previous post to yours.  This fellow has the stock exhaust just modified as the rest of us have done.  He doesn't have the true dual setup like I posted.  So anyone have a full dresser with true duals-how was the heat with lower fairing installed?

It's my friends bike however, he is not a member of the site.  After he had the pipes put on he put the power commander 5 and had it dyno'd by cycle solutions.  The Pipes sound great and he did say it was cooler however, I'm not sure how much cooler.  I'll talk to him tomorrow and ask him how much of a difference it made as far as heat.  I know that it sure performed better.  I do have a question for the SERG owners.  While stuck in traffic his bike died out a couple of times and when he went and asked the guy who dyno'd it he said it was because on the new engines it drops down to 1 cylinder and that is what's causing it.  Anyone else have this problem?

The bike will hold steady even in the 1 cylinder mode. Sounds like it needs more tuning. All the more credibility for the HQ Pro Tuner. I rode for at least 6 hours Sunday at extended 75 mph plus in 90F plus temps and the bike never went into the 1 cylinder mode in between towns and the oil temp never exceeded 134. Its fast and will never need a dyno or a map. :2vrolijk_21:

134*  ????   Must be a mis spell.  Doc

I'm sure you know this, but others just dropping in may not.

The "Parade Mode" only works at zero mph.  Any speed at all and mine kicks back into normal twin firing mode.

I will say that the so far stock '09 SERG does this quite often while riding in town and hitting stop signs or stop lights.  My '08 SERK with the V&H duals and oval mufflers with SE-AC and PCMIII, did kick down, but not as frequently.  I will admit that last weekend when we rode we had ambient over 100 and boy was it hot riding...

You can also kick in the single cylinder mode when in neutral and rolling the throttle forward.

Dan, any possibilty that I'll be seeing/hearing this bike. I'm about ready fro true duals.
Highway, where do you get the 10% drop in power, way way too extreme
Title: Re: SERG dual exhaust
Post by: drod2020 on August 14, 2009, 03:15:39 PM
Yeah totally no problem.  I'm heading out of town this weekend but I'm sure I can bring it down next week sometime.  As for the heat he said there was a temp drop but not to significant.  I'll call you when i get back in

Quick question, why you looking at true duals? Is there something about the 2-1-2 exhaust that's not getting it done for ya. Thanks bud.

Post by: LarryB on August 14, 2009, 04:52:27 PM
well it's like this, not really. the baffles are getting sweeter but I'm looking for a bit more rumble. in town it's too tame. was thinking about going to the 2.25" but I know it's the 2-1-2 combo that is keeping quiet. am thinking about getting some Bommcans, but if I can find another form and function homerun, then I'm all about that.  :2vrolijk_21:

Larry,

10% is certainly possible at the top end with a good 2:1 system, but may be a bit extreme when referring to the stock 2:1:2 setup.  With the TD setup you are faced with that radical bend on the rear head to get the pipe to exit on the left. I have routinely seen those bends glow red from the additional heat buildup in that restrictive bend. It will undoubtedly also increase heat on the left side of the bike. Other than for aesthetic reasons, I can't imagine why anyone would want to go back to a TD.

I have a Bub 7 true duels with a PC V and a Jet Scream intake with a K&N filter. It was also done by Cycle solutions back in June.
HP is 90 and torque is 108. I do not find this set up overly hot and I have lowers on all the time. In city riding at the stop lights the
heat does come up a bit and I have found it wants to stall out when it is really hot outside after sitting idleing at a light. If I give it
a but of throttle to bring the other cylinder back online it doesn't stall out, but it is close. The Bubs are great I love the sound of
them as they can be very loud when you want them to be and very mello when cruising down the highway.

The true dual vs 2-1 or 2-1-2 horspower/torque difference is way overblown. I have currently a SERG with 2-1-2 catless, Fullsac baffle that was Jet Hot coated and a TTS using Fullsacs map for the SERG.
Last bike was a 05 SEEG that had V&H true duals with Harley Screamin Eagle Pro's with Harley map cartridge (the one you installed with the Scan Tool) and a PCIII professionally mapped.
I can tell no difference in heat in traffic on either, wife at first thought the SERG ran hotter but has changed her mind. Got back from Key West last nite and the last trip was on SEEG with LOTS of start/stop and bike overheated several times. This trip same deal, I turned off the cylinder cancel deal because I got tired of the deal everytime I stopped so I assume it was overheating as well.
But big thing of this post, the SERG has not been on a dyno, Fullsac says to expect 95-97 Hp and about 110 or so torque with the 2-1-2 with 1.75 baffles and the TTS. The SEEG had 86 HP and 97 torque with the true duals as mentioned above, Butt feel makes new bike a little quicker, not much just a little.
So If you like 2-2 then go that way, hp/torque diff is so minumal that looks become a big thing. It yours buy and use what you like.

Maybe he is just checking out those reflectors on the forks and the bags
Title: Re: SERG dual exhaust

I'll have to say that he is definitely checking out the safety reflectors and maby wishing
that he still had them installed on his bike!!!! (A Road King by the way)

That's my story and I'm sticking to it!

You can also kick in the single cylinder mode when in neutral and rolling the throttle forward.

You can enable the EITMS function to run automatically before starting the bike by rolling the throttle forward for three seconds with the key set to the on position and the start/run switch in the run position. When enabled, the EITMS will engage when the specified parameters (head temp, rpm, and speed) are all reached.  Those specific parameters are contained in the owners manual.

You cannot manually engage the EITMS by rolling the throttle forward, it is automatic and either enabled or disabled by the above procedure.

Hey Larry, I put the Freedom duals on my silver SERG that already had the 1.75 Fullsacs. I definitely picked up the rumbling sound and was confirmed by Steve that this was normal.  As far as the heat issue-the right lower side is cooler than before and the left upper thigh is warmer.  Now I enable the HMS and in traffic it is bearable.  For sure better than it was and lower fairing still in place. :2vrolijk_21:
