Hey, i just orderd a powerbomb header for my raptor 350, is there going to be a noticable performance gain? Also fmf says it lowers the sound of the exhaust, is there that much of a diffrence? THanx

 

If you just got a header it wont make a real big difference in performance, but sound it could make a big difference. If you get the full kit from fmf with the jets, and the pipe you will see a big difference in performance.
