I'm in the same boat as you. I have a true duel set up with 50's on it and an x-pipe built in. I had all of this put on before I joined TS. Love my sound and top end did get quite a gain, but my off the line is sluggish. I'm in college and have no money to re-do my exhaust so that's out of the question.
I am courious about the paint though......I wonder if that would work....cause I would be up for that!
