Any body know much about this exhaust system? Taking possession of my bike and they are trying to sell me on these. They said they have moved the cat from the head pipe to the muffler for the heat issue. Also they tell me, if you remove the cat it drops the low end torque? Seems odd........want to upgrade exhaust for stag 1 but don't want anything to loud as they are getting really up tight about loud exhaust around here. Any suggestions would be appreciated!


Part Number 64800022

as far as exhaust goes, one word  FULLSAC 

You will not be disappointed. I use the Fulklsac headpipe, and 1.75" baffles. tuned with a TTS using a map that Steve (from Fullsac provided).

I would have to second this, just finished mine and very easy even for a ham fisted half a mechanic such as me.

this looks completely new - not in the se catalog - no cat in the header at all - hmmm

[timo482]

it "looks" like the cross over pipe is not squished, but the collector looks like its just a oval section of pipe, no way to tell till somebody has one in there hands. also lists 10 or newer probably due to O2 ports

After doing some research, I think they are made by SuperTrapp.

For $1,200 dollars I bet they are pushing them, for a fraction of the cost the Fullsac option  will perform probably better and not discolor at the outlet. Ive seen a number of the Nightstick mufflers designed for the 2010, 2 into 1 Street Glides and Road Glides and without exception the End caps turn a dark gold color it looks like Supertrapp is using the same equipment on this version.

If you go with this setup and decide later on that you don't like the mufflers, the larger diameter pipe will limit your choices for alternate mufflers.  Just thought I'd mention that, since I remember some original Rinehart True Dual users finding out the hard way they couldn't install their new favorite muffler on the nonstandard size Rinehart pipes.

Since they only claim a very modest increase in performance (unlike most pipe purveyors), I fail to see the benefit of the larger diameter pipes.  Is this just one more example of selling something based on perception rather than science, hoping to score some big bucks from folks who always think bigger is automatically better?  Don't know the answer but thought I'd offer it up as a point to ponder.

Appreciate all the input - I was trusting what the service / parts guys are suggesting buy seems they don't really know.........DOES THIS SOUND LIKE A FAMILIAR STORY!!!!!!!!!!!!! Wow, it only makes sense to go with the Fullsac system if not going with more engine work. Thanks to all for the advice and sharing the experience!

The real deal is.   Street legal

It won't affect warranty or esp

Right now it's the only pipe hey hae to sell

That is what has my attention right now.  I will need to look into these pipe and the warranty issues.  If this does not have the cat in them this May be an expensive option to get the heat problem under control.

I don't know about that Jerry.  I have a friend that put fatter diameter handlebars on his dyna and he swears it runs faster now!

Apples and oranges.  It's a known and proven fact that fat handlebars (or anything "billet") will indeed make a Dyna run faster.  On the other hand a fat rider will have the opposite effect.  It's one of those strange exceptions to the rule deals.

It's only street legal as a complete system, not as separate parts.  In other words, if one were to buy only the head pipes they would NOT have a legal system, since the cats are in the mufflers.  Eliminating the cats, any way you do it, results in an illegal system.  It can also be used by H-D to void the powertrain warranty if they so desire.

By moving the cats from the collector to the inlets of the mufflers they are basically just moving the source of the extra heat further rearward and splitting it into two sources, which is basically the way it was before they went to the 2-1-2 exhaust in 2009.  That might help the rider's right foot and lower leg, but I'm not convinced it would help a passenger all that much since the cats would now be closer to their feet.  What this really looks like to me is a way for Harley to capitalize on and profit from the fixation customers have on the heat from the catalyst in the collector on late model Touring bikes, while not running afoul of the EPA.  The real main benefit will be to Harley's profits.

If HD can install CATS in the mufflers surrounded by metal and insulation, then WHY? don't they cover them in the stock header pipes? A full shroud would reduce the radiated heat.

Retained heat apparently isn't an issue like on current Softail CAT-in-muffers, this new assembly, and most automobiles. I replaced my stock cans with earlier non-CAT EPA stamped SE slip-ons so I'm not concerned about the added heat.
