Well I tore the cat and the rest of the original exhaust off and put a 4 inch straight pipe on . Man does that old turbo sing now ! I am still getting contact on the firewall with the down pipe and I worked it over pretty good this time I think I'm going to get new body to frame bushings. When I went over to Jim's he pointed out that my cab was sitting lower than my bed I never noticed that before so thats next.
