There have been hundreds of posts on this subject in the last few months. Do a search and read through the topics. When you are done we'll be happy to answer any questions you have.

HMF, CT, Sparks, Duncan, ESR, GTYR, and a few others have been the most popular.

 

You know a good place online that you purchase from? anyone...

 

I get most of my parts from Rocky Mountain ATV. Good prices, and they don't gouge you on shipping either. [img]i/expressions/face-icon-small-smile.gif[/img]

 

I just bought a HMF and am really happy with it, BUT the ESR is the cream of the crop . You got to check them out!!!!!![img]i/expressions/face-icon-small-shocked.gif[/img]

 

From what Ive heard, Sparks wounds like its the best. Then again, it really depends on where you want it to hit. Thunder Alley can tune the pipe to how you want it (where the power comes on, noise level, ect). ESR, HMF, Dunacn, GYTR, theyre really all nice pipes.

 

Just from what i have seen on the forums I would say the Sparks, HMF and GYT-R setup are the most POPULAR. (not saying the best)

 

After reaading the pipe shootout on the dirtwheels buyers guide no pipe is REALLY superior to any other hp wise. I think the greatest hp difference was like 1hp and that just peak hp so another pipe could have slightly better low/mid/high hp. When picking a pipe just conmsider your budget and what sounds and looks nice. JMO

 

Thanks alot guys... i emailed another website, it was ask the Pro Doug Gust or something, and he told me alot of people like using the FatBoy 4, is this a good pipe? and i herd the sound is supposed to sound like it got *****, a nice sound that everyone knows ur around haha...AMA dont matter to me and cali laws dont apply to me...Im in New York, and im not racing any AMA anytime soon...thanks alot[img]i/expressions/face-icon-small-smile.gif[/img]
