Looking for some info on exhausts. Which is the better pipe for the KFX 400 (FMF FACTORY 4 W/ POWER BOMB) or (LRD PRO 4 SERIES). Hope someone can give me some info. Thanks

 

I did a lot of research on pipes before I went with a Yoshi system. It with a pro design intake, k&n, dyna ignition dyno'd right at 40hp. I haven't talked to anyone whos got that kind of power without getting into the engine. If you didn't know, Yoshi is the factory R&D for suzuki which is of course one and the same as the kawi 400. Pipe has been great, smooth power for fast trails and dunes.
