Description
Overview
The Flowmaster Flow FX Extreme Cat-Back Exhaust System is engineered specifically for the 2020-2026 Jeep Gladiator JT equipped with the 3.6L engine. Built to deliver a deep, powerful, aggressive tone alongside real performance gains, this stainless steel cat-back system replaces the restrictive factory setup with a free-flowing design that looks as capable as it performs. If you want your Gladiator to sound as serious as it drives, the Flow FX Extreme is built for the job.
At the heart of the system is a Flow FX series muffler, tuned to produce Flowmaster’s signature deep, powerful sound. The muffler features a center inlet and center outlet with a 3.00-inch outlet diameter and an overall length of 42.80 inches, working in concert with 3.0-inch mandrel-bent 409 stainless steel tubing for maximum exhaust flow and long-term durability.
Built for the Trail
What sets the Flow FX Extreme apart is its turndown-style dump exit positioned right after the muffler. By eliminating the over-axle tailpipe, this design improves ground clearance and departure angle — a genuine advantage when you’re tackling more extreme off-road situations. Fewer components hanging beneath your Gladiator means fewer things to snag on the trail, all while keeping that aggressive exhaust note front and center.

Easy, Bolt-On Installation
Flowmaster designed the Flow FX Extreme to make installation straightforward. The system uses factory hangers and factory mounting locations, and all of the necessary hardware is included. That means a direct, bolt-on fit with no guesswork — you can get your Gladiator back on the road or trail without fabrication or extra parts hunting.
Fitment
This cat-back system is purpose-built for the 2020-2026 Jeep Gladiator JT with the 3.6L engine. Because it’s engineered around the Gladiator’s factory hardware and mounting points, you get a precise, application-specific fit rather than a universal compromise.
The Flow FX Extreme is CARB compliant, making it a smart choice for owners in California and other emissions-regulated states who still want serious sound and improved flow. Backed by Flowmaster’s Lifetime Limited Warranty, this stainless steel cat-back delivers the confidence of a proven brand along with the durability of 409 stainless construction. For Gladiator owners who demand aggressive tone, added performance, and off-road-ready clearance, the Flow FX Extreme checks every box.
