Flowmaster's race-oriented American Thunder Extreme Cat-back system is designed to mount behind the factory catalytic converters, or most OEM style aftermarket H-pipes.

This American Thunder Extreme system delivers a super aggressive interior and exterior tone and is suited to the enthusiast who wants the most aggressive components they can purchase. Like all Flowmaster systems, the benefits include improved throttle response and power. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation.

  • Fits with most modified suspensions
  • Stainless Steel Construction
  • Patented Delta Flow technology
  • Lifetime limited warranty
