Product Details

The Flowmaster FlowFX Cat-Back Exhaust System delivers enhanced performance and an aggressive sound upgrade with straight-through muffler technology. This complete bolt-on system is engineered for enthusiasts seeking improved exhaust flow and a deep, powerful tone without excessive volume.

Key Features:

  • FlowFX straight-through performance muffler for optimal sound and horsepower gains
  • Dual 2.50-inch mandrel-bent 16-gauge tubing maximizes exhaust flow and reduces backpressure
  • 100% stainless steel construction ensures corrosion resistance and long-lasting durability
  • Large 4.50-inch black ceramic coated stainless steel tips for an aggressive appearance
  • Utilizes factory hanger locations for straightforward bolt-on installation
  • Clears factory spare tire location with no modifications required
  • Backed by Flowmaster's Lifetime Limited Warranty

This cat-back system provides the perfect balance between performance enhancement and refined exhaust tone. The mandrel-bent tubing maintains consistent diameter throughout each bend, eliminating restrictions and turbulence for improved exhaust velocity. The result is measurable power gains across the RPM range while delivering Flowmaster's signature deep, performance sound.
