check all the classifieds. people are selling bassani, magnaflow, bbk, mac etc, but you rarely see someone selling a dr gas. once you get one its on the car for life on most occasions.
Sorry, I am in favor of the VRS X-pipe. So inexpensive and the results and fit are great. I had this on my 00GT with a K&N and Flows and I went 14.0@100mph at 1600ft elevation track.
I did not go with them now because I wanted a catted pipe, and I am starting to like the sound of the H better.
