Jerry-

What size of glasspacks do you have? I have 24" and they are a little raspy at higher RPM's, but not too bad. I wanted 30", but they would have had to order them.

I have actually heard some people say that the 235's are more mellow with straight pipes than with glasspacks. Personally, I didn't have the nerve to try it.
