Yoshimura - Comp Series RS-4 Full System (Stainless)
The RS-4 is a unique design with predicated power, a side benefit of a quiet earthy exhaust note that speaks volumes for performance.
This Full System comes with a stainless steel header and mid-pipe, aluminum muffler sleeve, installation hardware, and detailed instructions to get you moving!
Stainless Systems come with a USFS approved Spark Arrested insert installed in the muffler.

Comments about Yoshimura - Comp Series RS-4 Full System (Stainless):
Great system, great price. Improves the bikes bottom end power imo. The biggest con would be that when you fall the plastics on the right side melts in a little on the muffler, which isn't that funny! Mounted on my Crf250 2012

Comments about Yoshimura - Comp Series RS-4 Full System (Stainless):
I put this pipe on my 2010 CRF 250, the power increase was unbelievable, has heaps more pop off the bottom but also screams on forever.
The only complaint i have is that it doesnt sound as good as say an akro or FMF.
But for the price it is amazing
