Product Details

The Flowmaster Force II Cat-Back Exhaust System delivers enhanced performance and aggressive sound for enthusiasts seeking a complete bolt-on exhaust upgrade. Engineered with all stainless steel construction, this system is built to withstand the elements while providing years of reliable service.

Key Features:

  • Super 50 Series performance muffler for powerful exterior sound with minimal interior drone
  • Mandrel-bent tubing maximizes exhaust flow and horsepower gains
  • All stainless steel construction ensures corrosion resistance and durability
  • Large 3.50-inch polished stainless steel tips for an aggressive appearance
  • Multiple exit styles included in kit for customizable installation
  • Uses factory hanger locations for straightforward, bolt-on installation
  • Easy installation with all necessary hardware included
  • Backed by Flowmaster's lifetime limited warranty

This complete cat-back system replaces your factory exhaust from the catalytic converter back, delivering improved flow, performance gains, and the distinctive Flowmaster sound. The mandrel-bent tubing maintains consistent diameter throughout each bend, eliminating restrictions found in crushed-pipe factory exhaust systems. The Super 50 Series muffler is specifically designed to produce an aggressive exterior exhaust note while keeping interior cabin noise to a comfortable level for daily driving.
