Speaking of RZs, they definately have the market on building pipes for RZ motors in Banshees.
Too much stupid argueing about whos tie is the redest. A pipe that is built to peak with 194 degrees of exhaust timing is going to run better with cylinders built with that timing. Put PTR mids on a drag motor and they are going to be down on power, but put some out of frame drag pipes on a stocker and it will be down on power compared to the PTRs. There is "NO" perfect pipe for everyone. I think Rockets, Shearer and CPIs are going to offer about the best top end you are going to find in a pipe you can still trail ride with. Are there pipes that will make more power, sure.
I think one of the things that is making Rockets what they are "IS" Ray. Small companies are nothing with out great customer service, and you really couldn't do a better job than him.
I run Rocket pipes and can keep up with some pretty fast bikes with my MX motor. I've actually had mine for quite along time, longer than most and I am still trying to figure out the best set up as far as porting and bolt ons to get the most out of them.
