Upgrade the exhaust performance and sound of your 1994-1997 Ford Mustang GT or Cobra with the Flowmaster American Thunder Cat-Back Exhaust System, Part 17112. Designed for Mustang models equipped with a 4.6L SOHC or 5.0L engine, this emissions-legal bolt-on system delivers an aggressive exterior exhaust tone and the deep, powerful sound associated with 1990s Mustangs. It fits both coupe and convertible body styles and is engineered for a straightforward installation using the vehicle’s factory hanger locations.
The Flowmaster American Thunder system uses free-flowing 2.50-inch mandrel-bent, 16-gauge aluminized steel tubing to support improved exhaust flow and long-term durability. A pair of Super 44 Series performance mufflers provides a bold, performance-oriented sound while the dyno-tuned design helps optimize overall exhaust performance. Factory-style flanges support proper fitment and installation, making this system a practical choice for street-driven Mustang builds, restoration projects, and performance upgrades.
All required hangers and installation hardware are included, along with easy-to-follow instructions. The system is designed as a direct bolt-on replacement and uses the original mounting points to help simplify installation. Verify your vehicle’s engine, model, and body style before ordering. Flowmaster Part 17112 is intended for 1994-1997 Ford Mustang GT and Cobra applications with either the 4.6L SOHC or 5.0L engine.
