i'm just curious for the yz426f, i've heard that dr. d exhaust is really good for the yz250f
What ever you buy, SuperTrapp it. Be super loud and legally arrest sparks. You can change the back-pressure and try to change the throttle response. The headpipe "tuneing" would be the real Dyno answer. Go with the pro's. They listen to their expert tunewho get paid to play. Must be nice.
P.S. I cant agree with prime. I say be as quiet as practical unless on a closed course, and even on some of those, a little forethought is necessary. Land gets taken away DAILY as more complain about noise, especially with thumpers. Noise, (and maybe prime),:uh:
