Product Details

The Flowmaster American Thunder Axle-Back Exhaust System delivers aggressive sound and performance gains for enthusiasts seeking a bold exhaust upgrade. This cat-back replacement system features Flowmaster's race-proven Outlaw Series mufflers, engineered to produce a deep, powerful exhaust tone while improving exhaust flow for enhanced horsepower and torque.

Key Features:

  • Race-proven Outlaw Series mufflers for aggressive sound and maximum flow
  • Full mandrel-bent tubing maintains consistent diameter for optimized exhaust velocity
  • Stainless steel construction resists corrosion and ensures long-term durability
  • Large 4.00-inch polished stainless steel tips for an aggressive appearance
  • Dyno-tuned design for proven performance gains
  • Bolt-on installation replaces factory axle-back section
  • Backed by Flowmaster's Lifetime Limited Warranty

This American Thunder system combines Flowmaster's decades of exhaust engineering expertise with premium materials and precision manufacturing. The mandrel-bent tubing eliminates restrictive crush bends found in factory exhausts, while the Outlaw Series mufflers provide an unmistakable muscle car sound that turns heads. Perfect for drivers who want professional-grade performance and sound without a full cat-back system replacement.

paypal would of been easier but all of my payment options were not available through the link.

Google search found the item I was looking for on the Autoplicity website. Item was cheaper than anyplace else. Ordering was easy using Amazon ID.
