The American Thunder setup utilizes Flowmaster Super 40's and a resonator delete.
If you are interested, I have a used pair of 3in Super 40's for sale and you can have your shop weld in
straight pipe in place of the resonators.
Best price I've found so far is 600 shipped. Should I just pull the trigger and buy it or wait a little longer and see if I can find it for less? If anyone has bought it cheaper within the last couple of months send me a pm with info. Thanks.
I'd pull the trigger on that. 600 to your door might just be about the best deal for this setup new that you'll find. Awesome exhaust I've had it for a few years now and the note just got better and better the more miles I put on it. Good choice!
