Rasp doesn't bother me either, personally. I'm just pointing out that it does bother some people, so that's a legitimate reason to go with HFCs vs. test pipes. What ever happened to the dyno you were going to get on the Berk test pipes per your other thread? Berk Test Pipes impression

I want to see numbers -- numbers are more meaningful than sound to me.
