Product Details

The Flowmaster Flow FX Extreme Cat-Back Exhaust System is a performance stainless steel cat-back exhaust built to improve exhaust flow, deepen your truck or SUV's sound, and hold up to hard use. Each system replaces the factory exhaust from the catalytic converter back. It is a bolt-on upgrade for trucks and SUVs, and it is also sold as a muffler and exhaust kit.

Key Features:

  • Flow FX series performance muffler: a straight-through design that improves exhaust flow and gives a deep, aggressive to moderate tone.
  • 409 stainless steel construction: durable, with good long-term corrosion resistance.
  • Mandrel-bent tubing: keeps the pipe diameter consistent through the bends so exhaust gases flow freely and power improves over stock.
  • Turndown dump-style exit: sits right after the muffler and eliminates the over-axle tailpipe. This improves ground clearance and departure angle off-road.
  • Easy installation: uses factory-style hangers in the stock mounting locations, and complete installation hardware is included.
  • Lifetime Limited Warranty: backed by Flowmaster.

Flowmaster has built performance mufflers and exhaust systems for decades. The Flow FX Extreme line is aimed at truck and SUV owners who want a stronger exhaust note, better flow, and more off-road clearance. Select the specific part number below to get the right system for your application.

Great

Long and not effective

Good shops and the best..

A dealership broke one of the parts of a rim I have on a car and needed a part in a pinch! Price was great and shipping was incredibly fast! Really happy with the selection and listing such a specific part, other sites just listed part numbers without pictures so THmotorsports made it easy to trust.
