Delta Flow
This American Thunder cat-back exhaust system delivers a moderate to aggressive exterior sound with a mild to moderate interior tone and is best suited for the enthusiast who wants their performance to be heard. The system features a Super 50 Series performance muffler with a built-in resonator keeping the interior drone down so you can carry on a conversation without having to raise your voice. The 2.50-inch mandrel-bent aluminized steel tailpipe uses the factory hanger locations for an easy installation and exits out behind the right rear wheel. The system includes all necessary parts, hardware and installation instructions making this an easy install that you can do at home with basic hand tools. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage.

  • Mandrel-bent 16-gauge Aluminized Steel Tubing
