Product Details

The Flowmaster American Thunder Cat-Back Exhaust System delivers aggressive performance sound and proven power gains for your truck. This direct-fit system is engineered to maximize exhaust flow while providing the deep, throaty tone Flowmaster is famous for.

Performance Benefits:

  • Dyno-tested gains of up to 13 horsepower and 12 lb-ft of torque over stock exhaust
  • Features Flowmaster's legendary Super 10 series chambered muffler for deep, aggressive exhaust note
  • Mandrel-bent 3.0-inch and 2.5-inch diameter tubing eliminates restrictive crush bends
  • Constructed from durable 16-gauge 409 stainless steel for corrosion resistance

Installation:

  • Direct-fit design uses factory mounting locations for bolt-on installation
  • Complete hardware kit and factory-styled hangers included
  • No cutting or welding required

Tuned to deliver quality sound both inside the cabin and outside, this American Thunder system provides the perfect balance of performance and acoustics. Backed by Flowmaster's Lifetime Limited Warranty for confidence in long-term durability.
