Increase the performance in your 2012-2013 Mustang Boss 302 with a Flowmaster American Thunder cat back exhaust system.Flowmaster proudly introduces our new 817553 American Thunder Cat-back exhaust, engineered specifically for the 2012-2013 Boss 302 Mustang. 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. The custom-engineered 60 Series Delta Flow mufflers deliver an aggressive, powerful exterior sound and a moderate interior tone with very little resonance. The 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 Mustang Boss 302.

Flowmaster - The Exhaust Technology Company Flowmaster operates the only exhaust Research & Design facilities of its kind in the world, centered around the SuperFlow SF-7100 engine dynamometer complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dyno's.
Through use of these dyno's, Flowmaster's engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers "to the ground."
Flowmaster also utilizes Spectrum Analyzers to fine "tune" the sound of each of the eleven different series of mufflers that Flowmaster currently offers, both for peak performance and just the right sound levels and tones. Flowmaster's dedication to quality is what makes them the exhaust industry leader for Latemodel Mustangs and SVT Lightnings!
This is by far the best experience I have ever had buying parts for my mustang. There is no other place for me, then LatemodelResto. I have bought multiple parts over multiple orders and have had nothing but a smile from ear to ear. Aaron Westerman was my contact person from LatemodelResto. I could not ask for a better customer service representative than him! He went above and beyond multiple times for me and made my experience with Latemodel the reason I keep coming back. LatemodelResto will continue being my #1 stop for my Mustang parts.
