Product Details

The Flowmaster 817507 American Thunder Cat-Back Exhaust System delivers enhanced performance and a moderate exterior exhaust tone upgrade for your vehicle. This complete bolt-on system is engineered to connect directly after the factory catalytic converter, providing improved exhaust flow while maintaining emissions compliance.

Key Features:

  • Mandrel-bent 16-gauge stainless steel tubing for maximum flow and durability
  • Dual tailpipe exit configuration for aggressive styling
  • Moderate exterior exhaust tone—deeper than stock without excessive noise
  • Designed to clear factory spare tire location
  • Utilizes factory hanger locations for secure mounting
  • Includes all necessary hangers and hardware for straightforward installation
  • Backed by Flowmaster's Lifetime Limited Warranty

This cat-back system is designed for enthusiasts seeking improved exhaust flow, a quality sound upgrade, and long-lasting stainless steel construction. The mandrel-bent tubing maintains consistent pipe diameter throughout bends, reducing backpressure and maximizing performance gains. Installation uses factory mounting points for a clean, factory-like fit.
