[steve650]

Hi everyone,
I wanna make some extra HP from a Suzuki RM 125, 1998. The top end and bothom end is brand new. Of course I wanna buy the pipe that will makes the most power to the rear wheel! Did one of you have idea what brand, and model to buy? Did one of you already installed one? if so anny advices and inputs will be really apreciated! Thanks, steve :think:

I have a 97 rm125 and put a fmf fatty on it and felt a big difference everywhere. My jetting was a little rich before, when i put the pipe on it was almost perfect. You mite have to jet leaner for best results.

A friend of mine had a 96 RM250 with lots of motor mods and he used a Bill's pipe. He said it made more power throughout the entire rpm range. However, I don't think you can go wrong with FMF.

ok, thanks. I was a little confused cause a friend of me tell me that FMF pipe was a piece of crap. Thanks!

Well it depends on the bike, mine it was sweet, but my buddies it made the power worse.

Get a pro circuit pipe of some kind, and team it with the factory sound shorty. Did it on my yz and it gave it a huge boost in power all-round.
