What are you trying to improve?
What don't you like about stock?

SuperTrapp is a "tuneable" spark-arrester

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.

426,
Check out this link http://bbrmotorsports.com/Products/ExhaustSystems/250exhaust.htm
Removable spark arrestor for closed course or forest, and the two headers for torque or rev. Not to mention how great it looks!;)
Smooth

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:
