Product Details

The Flowmaster Force II Cat-Back Exhaust System is a stainless steel performance exhaust (also called a cat-back exhaust or cat-back kit) built to give your vehicle a deeper, more aggressive tone and better exhaust flow. Flowmaster has been known for its muscle-car exhaust sound for decades. The Force II line is designed for drivers who want that sound without giving up everyday drivability.

Key Features:

  • Stainless steel construction for corrosion resistance and long service life
  • Cat-back design replaces the restrictive factory exhaust components from the catalytic converter rearward
  • Force II muffler with an aggressive, deep exhaust note under acceleration
  • Mandrel-bent tubing helps keep the pipe diameter consistent through bends for smooth exhaust flow
  • Bolt-on installation with no cutting or welding needed in most applications

Upgrading to a Flowmaster Force II cat-back system can improve exhaust flow and sound while adding a more performance-oriented look at the rear of the vehicle. Each system is engineered to Flowmaster's standards for fit and finish. Choose the system option that suits your build.
