A crapload of people are running the DR.D exhaust system, this is the same one as the GYTR exhaust as well.

Akropovic is supposed to be the cats meow from what I hear.

Search and you'll find lots of info.

Personally liking the looks and build of the pro circuit.

Some dyno numbers comparing them all would be really nice IMO

I hear the Yoshimura is Best.....according to MXA?

They dynoed and tested 8 pipes.

I started off with a Dr.D full TI. carbon which was way better than stock. but now i have a yosh ti. ti . system with the pim2 an data box hand down the best pipe. even without the pim2 an data box it shines .

love my mrd pipe and its $275 price tag what company even comes close to this value?? Also the mrd really opens up the mid to top end of the powerband and the build quality should make the dr.d , pro-circuit, fmf boys take a hard look at the "quality" of there offerings. Oh did I mention the lifetime defect warranty???

MRD did some research and decided based on the findings that there was no reason to replace the stock header. His slip-on does open up the upper range a lot with no particular low end penalty. The price and service make it a bargain.

I put the FMF on and I am very happy! smoothed out the hit on the bottom and it pulls much farther.

I'm running the FMF as well and couldn't be happier. I noticed the same - smoothed out the power, and it pulls much harder up top.

I had a Yoshimura system on my previous bike and the build quality was TERRIBLE.

Just think how happy you'd be if you had the $200+ difference between that and an MRD still in your pocket.

I assume you paid more than $275, yes. And whether you did or not, 95% of everyone else would have to.

If you had any brains...only go with the Dr. D. system...like me...unless you pretty much want equivalent performance which you can pretty much get with all the other systems...However, if your initials are RC I would say you should think hard, otherwise, pick what looks good, fits pocket book budget and the sounds good to you, I promise your lap times won't change. That's top dollar advice....:smirk:
