What are you guys thoughts/experience with the Yoshi rs2 pipes? Are they any good? Compared to the fmfs?
Is there anything negitive about them? as far as why people arent buying/have them?
I will prob have to get a programmer right? cause if i bought the yoshi i could not just throw it on and use it could i?

You could just throw it on and run it, but the bike runs lots better with a fuel programmer.
:)

I gotcha...but i am going to get pretty bad backfireing arent i?
You dont have a Yoshimura rs2 pipe do you? what your imput on it/them?(someone on here has to have one or have heard about them?)

I've got an FMF Q4 with the FMF head pipe.

It seems that the FMF is more popular, maybe because they were available for the WR-250R and X before the RS2.
Myself, I think the FMF mufflers look better, and I know the Q4 ain't too loud.

I had to run my WR-250R without a fuel programmer for one ride after my Power Commander quit working.
I had the FMF exhaust on the bike, and I don't remember the popping being too bad.

What I do feel is this:
The bike runs and responds to the throttle so much better with a fuel programmer that I'd probably get that before the exhaust if money were tight. :)
