ok i know im gonna get some heat for this cause people bash the fmf pipe all day .....but team epic can am was running that pipe for a reason.....i have had two pipes on my ds ...one was the FMF 4.1 with a mega bomb header ....the second pipe that i am currently using is a ron woods drag pipe......i can honestly say that i liked the fmf better ....the sound was nicer and it had the same exact seat of ur pants feeling as the ron woods.....i am switching back to the fmf as soon as i get a chance , i am actually confident in saying that fmf with mega bomb reved out better then the woods pipe in my opinion.
