I have a 1979 Pontiac Trans Am....it has a 403 with a 700r4 transmission in it. I am looking to put headers and a new exhaust system in it....what do you guys think is a good set up...I was looking at Hooker Headers and the Flowmaster Super 40 American Thunder muffler out of the Classic Industries catalog...any suggetions would be helpful...thanks in advance.
