Product Details

The Flowmaster 817748 American Thunder Axle-Back Exhaust System delivers an aggressive sound and performance upgrade for your vehicle. This complete bolt-on system features Flowmaster's legendary Super 10 Series performance mufflers, engineered to provide maximum exhaust flow and that signature deep, aggressive tone enthusiasts demand.

Key Features:

  • Super 10 Series performance mufflers for maximum flow and aggressive sound
  • 16-gauge mandrel-bent 3.00-inch stainless steel tubing for optimal exhaust velocity
  • Large 4.00-inch polished stainless steel tips for a premium finished look
  • Full stainless steel construction resists corrosion and ensures long-lasting durability
  • Utilizes factory hanger locations for straightforward bolt-on installation
  • Dyno-tuned design optimizes horsepower and torque gains
  • Backed by Flowmaster's Lifetime Limited Warranty

This American Thunder system is designed as a direct-fit axle-back replacement, allowing you to upgrade your exhaust note and performance without the complexity of a full cat-back system. The mandrel-bent tubing maintains consistent diameter throughout each bend, eliminating restrictions and maximizing exhaust flow. Installation uses your existing mounting points, making this an ideal weekend upgrade for enthusiasts seeking that distinctive Flowmaster sound.
