You might want to do some research into other systems for the V-6, S-197 Mustang. I have heard one with the Flowmaster system, and for lack of a better term, it sounded "Ricey", IMO. JBA, and Magnaflow, also produce true dual systems for the V-6 Mustang. Try to listen to Cars with exhaust systems from the three Manufactures, decide for yourself, and "buy once".
