Description
Overview
The Flowmaster American Thunder® Exhaust System Kit is engineered specifically for the 1998 Ford Mustang GT and Cobra equipped with the 4.6L engine. This complete bolt-on catback exhaust system is emissions legal and CARB (California) compliant, delivering the free-flowing performance and unmistakable Flowmaster tone that fans of a true performance exhaust demand. Every component is designed to work together, so you get a cohesive car exhaust upgrade rather than a mismatched collection of parts.
At the heart of this exhaust system are a pair of Super 44™ Series mufflers, known for their deep, powerful, and iconic voice. Flowmaster rates the sound level as aggressive to moderate, giving your 4.6L Mustang serious presence without being one-dimensional. From the free-flowing 2.50-inch mandrel-bent inlet pipes to the dual aluminized steel tailpipes, this borla exhaust and corsa exhaust alternative is built to breathe and built to be heard.
Key Benefits
Because this system uses the factory hanger locations, installation is quick and straightforward. The included U-bolt clamping hardware and easy-to-follow instructions mean you can bolt on this exhaust system kit at home without cutting or fabricating custom exhaust pipe sections. The result is a clean, professional fit that looks as good as it sounds.
The system is finished with a pair of long 2.50-inch 304 stainless steel tips for a genuine show-car look. That stainless steel exhaust exhaust pipe styling pairs perfectly with the silver-finish aluminized steel piping, so the visual upgrade matches the performance gains. Whether you’re comparing magnaflow exhaust, walker exhaust, or pe exhaust options, this Flowmaster catback delivers a purpose-built package for your Mustang.
