Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is a bolt-on, emissions-legal upgrade engineered specifically for 1994-1997 Ford Mustang GT and Cobra models equipped with the 4.6L SOHC or 5.0L engine. Built to recapture the iconic deep and powerful Mustang sound of the 90s, this complete cat-back package pairs free-flowing tubing with proven muffler technology to deliver an aggressive tone and improved exhaust flow without the guesswork of a custom build.
At the heart of the system are 2.50-inch aluminized steel mandrel-bent pipes. The mandrel bends preserve inside diameter through every curve, promoting smooth, unrestricted flow, while the aluminized steel construction stands up to the heat and demands of daily driving. Factory-style flanges and factory hanger locations mean the system lines up right where your Mustang expects it, making installation quick and straightforward.
Key Benefits
This American Thunder setup uses a pair of Super 44 Series mufflers to produce an aggressive sound level that complements the classic Mustang character. The dual tailpipe configuration finishes the look with a silver pipe color and the purposeful, muscular exhaust note enthusiasts expect from a performance cat-back. Because it’s designed as a true bolt-on, you get maximum performance with a clean, factory-fit appearance.
