which company makes the best full exhaust system for the speed? is hmf the only company so far making pipes for cannondale quads? thanks

 

big gun does and so does bill's pipes.

 

Curtis sparks racing makes a pipe for it to. I have one of his pipes on my 400ex and it helped out big time. He also builds some of the top pros engines. All of his stuff is top of the line and works. There website is www.sparksracing.com.

 

FMF makes them too. I think that they are all slip-ons. If they do make full exhaust, it would probably be a waist of money... I don't really see how they could make the header any better, I mean, it just comes straight out the back... doesn't look like it has much room for improvement (but what do I know... I could, very likely, be wrong)
