Give your S197 a distinctive sound with a Flowmaster American Thunder Axle Back Exhaust System for the 2005-2010 Ford Mustang GT & GT500. It features a pair of specially-designed super 44-series mufflers, which provide a deep and aggressive exterior tone. Through extensive testing, this kit has shown horsepower and torque gains, as well as weight savings over the stock mufflers. Features 4" polished stainless tips with the Flowmaster embossed logo. This aggressive-sounding system is designed to replace the original rear-mounted mufflers located behind the Mustang rear axle. With easy fit in mind, the exhaust system is mandrel-bent from 16 gauge stainless for maximum performance and includes specially selected super 44-series mufflers to support the performance image of the car.
As an American Thunder Mustang Exhaust System, it delivers an aggressive exterior tone with a moderate interior sound level that is suited to the Mustang enthusiast who wants their performance to be heard. Like all Flowmaster Exhaust Systems, the benefits include improved throttle response, power, and mileage. Designed for an easy fit, the system does not require cutting of the factory system and includes all necessary parts and hardware for easy installation.
