I know this is an old subject by now, but I just purchased a new 03 crf450 and am looking to put an aftermarket exhaust on. Anybody reccomend a slip-on/system that will add to the low end. Noise is OK with me .... :aj:
Yeah, sure, I can offer a suggestion! Probably the best all around pipe you can buy (especially if noise is OK with you) is the FMF Q silencer! Lighter than stock, great gains, and the noise would probably be OK with you!
