Flowmaster Part Number: 817553

Flowmaster "American Thunder" 3" Stainless Steel Cat-Back Exhaust Kit with 4" Polished Tips for 2012 Boss 302 Mustangs.

For the serious Boss 302 enthusiast who is looking for all the performance benefits of a complete Cat-Back dual exhaust system, this is it! Designed to work specifically with and to retain the factory Boss 302 side exhaust, incorporating flanges to retain the OE side-exit pipes.

As an "American Thunder" system, it delivers an aggressive exterior sound level and a moderate interior tone that is suited to the enthusiast who wants to be heard. With maximum performance and easy fit in mind, the system is mandrel bent from 409S stainless steel and includes specially engineered 60-Series mufflers with 4" polished tips featuring "Delta Flow" technology that delivers an aggressive, powerful exterior sound and a moderate interior tone with very little resonance.

Like all Flowmaster systems, the benefits include a substantial performance gain with mid-range torque that you can feel with the Scavenger X-pipe, improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and a side pipe spacer with larger 3/4” holes, which is a popular modification in itself.
