Great sounding exhaust!
Pipe/silencer looks and performs great! Bolted on easily. FMF said stock jetting should work but I had to re-jetted from 120 up to 135.

FMF 4.1 review
The fit was dead on. The stickers got mostly burned off after the first time out. Seemed to give the machine more snap off idle and sounds awsome!!!!!

Great pipe for a great price
This pipe is phenominal. It gave my bike a lot more low end which is what i wanted. It mounts easily, sounds great, and its just an all around good pipe.
