For the RZ conversion there are only 2 brands of pipes that clear the powervalves without denting, Rockets and PTR's. I have the Rockets on my RZ and had a chance last fall to try a new prototype. I have two sets on order, to replace my Rockets and my FMF's and they should be in this month. I would strongly recommend these pipes, pull better off bottom then the Rockets and everywhere better than the FMF's which I have always liked. Don't let others fool you FMF's are good and I have beet severel other brands constantly with them.

Thanks for the info on the conversion. I ride once in a while. More later than sooner. I like riding trails, gravel roads, and drag racing also.
