Product Details

The Flowmaster Force II cat-back exhaust system pairs a Flowmaster Series muffler with mandrel-bent tubing to give a deep, aggressive exhaust tone and better exhaust flow. It replaces the factory exhaust from the catalytic converter back, so it is a bolt-on upgrade for drivers who want more sound and performance without modifying the engine.

Key Features:

  • Series muffler: Flowmaster's tuned muffler design delivers a deep, muscular exhaust note.
  • Mandrel-bent tubing: Keeps the pipe diameter consistent through the bends to reduce flow restriction.
  • Cat-back design: Replaces the stock system from the catalytic converter rearward, so the factory emissions equipment stays in place.
  • Durable construction: Built for long service life and a clean, finished look at the tailpipe.
  • Bolt-on installation: Designed to install with common hand tools and no cutting or welding in most applications.

Flowmaster has built performance mufflers and exhaust systems for decades. The Force II line is aimed at drivers who want a noticeable sound upgrade, better exhaust flow, and a sturdy, well-fitted system.
