I was reading the post about exhaust systems, and I decided to check out a couple of websites. The Magnaflow site claims 22.9 hp and 25.4 ft-lb on an
03 Cobra. That seems like an awful lot from an exhaust system. Is this a realistic expectation from an exhaust system (any, not just Magnaflow). If not, what could one reasonably expect from a good aftermarket system?- posted
