    Video Review & Installation

    Hey everyone I’m Justin with AmericanMuscle.com and I’m taking a look at Flowmaster’s Pro Series axle-back exhaust for your 2011 and up Mustang GT. The Pro Series designed to give you that classic Flowmaster sound yet it’s slightly less aggressive than some of their other options. The exhaust features Flowmaster’s perforated tube style mufflers, which exit through dual 4 inch polished tips. The install should only take you about an hour using standard hand tools. Now that’s take a listen to how Flowmaster’s Pro Series sounds compared to your factory exhaust.
