I am thinking about putting an FMF Q pipe on my '03 YZ450F. I would appreciate any info on this pipe or any other pipe that is a little less noisy. By info I mean seat of the pants feel, excessive overheating etc. Thanks in advance. :banghead:

I have 1 on my 426 (see garrage)......I like it, it keeps it legal and spartarrested yet it seems to dull the power and throttle responce. (cant verify, bike came /w/ it)

I have one on my 04 450. It mellows the power a bit from bottom to mid seems about the same on top. Not a huge difference. I am able to run the same jetting with the Q and the stock muffler. It is quite a bit quieter than stock. But not WR quiet.
