Product Details

The Flowmaster American Thunder Cat-Back Exhaust System delivers aggressive exterior sound and moderately aggressive interior tones while maximizing performance. This emissions-legal bolt-on system is engineered specifically for trucks with coil spring rear suspension, featuring a stainless steel 50 Series HD muffler with large 4.00-inch internals for optimal flow and the distinctive Flowmaster sound.

Key Features:

  • Mandrel-bent 3.00-inch stainless steel tubing reduces restrictions and maximizes exhaust gas flow
  • Dual exit configuration offers two options: side exits behind rear wheels for towing or rear exits under the bumper
  • Includes pair of 4.00-inch polished stainless steel tips for a premium finish
  • 50 Series HD performance muffler with 4.00-inch internals for aggressive sound
  • Dyno-tuned for maximum performance gains in acceleration, passing power, and fuel efficiency
  • Uses factory hanger locations for straightforward installation
  • Clears factory spare tire without modifications
  • Complete kit includes all necessary hardware, hangers, and detailed installation instructions

This American Thunder system is backed by Flowmaster's Lifetime Limited Warranty and is manufactured in the USA. The DOR/DOS (Dual Out Rear/Dual Out Side) configuration provides flexibility for different driving needs while maintaining optimal performance. Note: Not compatible with optional air bag suspension.
