I dunno about the exhaust, my stock just keeps getting louder. <_< Knock some baffles out of yours. I think that's what's happening to mine, and it's only (kinda) loud above 2 grand. But, uh, I'm 23 and I still live at home.
When I graduated from college I got a job that was in my hometown for a few months, and soon I'm moving. Where do you live that you got an exhaust ticket?
