Just picked up an 05 CRF450. Curious to know what is the best exhaust set up for this bike. My 03 CRF450 had the FMF Ti-4 with the powerbomb header. That was incredible, but I do like the Pro Circuit lo-boy on my buddies 04 CRF450.
Also, when I picked up the bike from my local shop last night, their parts dept had nothing in stock for an exaust system, does the 04 set up's fit on the 05??
