Flowmaster 817494 American Thunder Cat-Back Exhaust for 2005-2010 Ford Mustang 4.6L & 5.4L

Flowmaster Cat-Back exhaust systems are the ultimate performance upgrade for your exhaust system. A cat-back system replaces all of your factory exhaust after the catalytic converter with mandrel-bent exhaust pipes to maximize exhaust flow, reducing exhaust temperatures and backpressue while improving sound and fuel mileage. Flowmaster thoroughly tests all of their highly engineered exhaust systems on the dyno to ensure optimal performance and a great fit, every time. This system, like all Flowmaster Cat-Back exhausts, was designed and fabricated by experienced Flowmaster techs who know how to pair the correct pipe size, muffler and exhaust tip for the best look, sound and flow. Get the most from your ride with a Flowmaster exhaust system today!
