First, I want to say that RapRap has the best sounding set pipes I have ever heard. I heard him take off up an Interstate Highway from two miles away and I knew it was him.
I too have a set of Mellowtones steelpacks from Brockman but mine are the 12". I love to get next to the Harley's with their straight pipes and rap mine off as we go through the gears. My wife says that it's not a case of "if" I get a muffler ticket, but "when" I get a ticket.
