Product Details

The Flowmaster 817784 American Thunder Cat-Back Exhaust System delivers a perfect balance of performance and sound for enthusiasts seeking an aggressive exhaust note without excessive drone. This complete bolt-on system is engineered to replace your factory exhaust from the catalytic converter back, providing noticeable power gains and a distinctive muscle car tone.

Key Features:

  • 2.50-inch mandrel-bent stainless steel tubing for maximum exhaust flow and durability
  • Dyno-tuned configuration optimized for horsepower and torque gains
  • Moderate to aggressive sound level—perfect street performance tone
  • Specially designed high-flow muffler and resonator for optimal sound control
  • Dual 3.00-inch polished 304 stainless steel tips for a premium appearance
  • Utilizes factory hanger locations for direct bolt-on installation
  • Premium stainless steel construction resists corrosion and discoloration
  • Backed by Flowmaster's Lifetime Limited Warranty

The American Thunder series represents Flowmaster's most popular cat-back system line, combining their legendary performance engineering with straightforward installation. Mandrel-bent tubing maintains consistent diameter throughout each bend, eliminating turbulence and restrictions found in crush-bent systems. The result is improved throttle response, enhanced exhaust scavenging, and that unmistakable Flowmaster sound that turns heads at every stoplight.
