Product Details

The Flowmaster American Thunder Cat-Back Exhaust System delivers a perfect balance of aggressive sound and performance gains for your vehicle. This complete bolt-on system is engineered to enhance horsepower and torque while producing Flowmaster's signature moderately aggressive exhaust note.

Key Features:

  • 80 Series Cross-Flow Performance Muffler for improved flow and power
  • Specially tuned resonator to optimize exhaust tone and reduce drone
  • Mandrel-bent 16-gauge aluminized steel tubing maintains consistent diameter for maximum exhaust flow
  • Dual 3-inch polished stainless steel tips for a premium appearance
  • Dyno-tuned design ensures optimal performance across the RPM range
  • Utilizes factory hanger locations for straightforward installation
  • Includes all necessary hangers and hardware for a complete bolt-on installation

This American Thunder system is designed for enthusiasts seeking a noticeable performance upgrade with an aggressive yet refined exhaust tone. The cat-back configuration replaces everything from the catalytic converter back, making it a comprehensive solution that's both emissions-compliant and performance-oriented. Professional installation is recommended for best results.

very fast processing received product within a few days. fair prices. will do business with again.

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!
