For owners of Ford’s amazing 2012 Mustang Boss 302, the puzzle of finding the ideal performance exhaust has just been solved.
Flowmaster proudly introduces our new 817553 American Thunder Cat-back exhaust, engineered specifically for the Boss 302. A full 3.00” diameter throughout, this all-409S stainless steel true Cat-back system features our patented Scavenger X pipe, and incorporates flanges to retain the OE side-exit pipes, as well as custom-engineered 60 Series Delta Flow mufflers for an aggressive, powerful exterior sound, and a moderate interior tone, with very little resonance. 4.00” diameter polished tips provide the finishing touch to the back of the car.
The bolt-on exhaust comes with all necessary installation hardware, and even includes side-pipe spacer plates with larger .75” holes- a popular modification in itself. The system provides a substantial performance gain, and with the detailed instructions is easily installed at home, or by a professional. Like all Flowmaster stainless steel systems, our Limited Lifetime Warranty means you’ll never need to buy another exhaust for your Boss.
