Description
Overview
The Flowmaster Flow FX Cat-back Exhaust System is a complete bolt-on upgrade engineered to deliver a deeper, more aggressive exhaust note alongside real performance gains. Built around Flowmaster’s Flow FX “straight-through” muffler design, this cat-back system replaces your restrictive factory piping with free-flowing components that let your engine breathe while giving your truck a bold, custom presence.
Every part of the system is manufactured from durable 409S stainless steel throughout, so it stands up to the heat, road spray, and everyday abuse that comes with driving and towing. A 3.00-inch inlet pipe feeds a single inlet/dual outlet Flow FX muffler, and dual 2.50-inch mandrel-bent stainless tailpipes carry the flow to the rear for maximum performance and that signature straight-through sound.
Sound & Performance
The Flow FX muffler is tuned for an aggressive-yet-moderate tone — deep and purposeful under throttle without being unbearable on the highway. The dual tailpipes exit out the sides at an angle behind the rear wheels, a smart design that directs exhaust away from your boat or travel trailer when towing. The system is finished with a pair of large 4.50-inch diameter black ceramic-coated 304S stainless steel tips featuring an embossed logo, adding a custom look that pairs perfectly with the deep Flow FX sound.
Key Highlights

- Dual 2.50-inch mandrel-bent stainless tailpipes for smooth, unrestricted flow
- Side-exit angled tailpipes route exhaust away from your boat or trailer when towing

- CARB (California) compliant — Emission Code 5
Easy Installation & Fitment
Designed as a true home-installable upgrade, the system uses all the existing factory hanger locations and includes an additional hanger to mount the new left-side tailpipe. Everything you need comes in the box, including installation instructions and all necessary hardware, so you can complete the job in your own garage. The muffler and dual tailpipes are all included in the kit.
Fitment note: this system fits both 2- and 4-Wheel Drive applications. Please note this product carries a California Proposition 65 warning. If you’re after the combination of a great straight-through sound, maximum flow, and a custom finished look with ceramic-coated tips, the Flowmaster Flow FX cat-back delivers on every front.
