The Flowmaster Outlaw Extreme Cat-Back Exhaust System is engineered for Jeep Gladiator JT owners who want maximum sound, increased performance, and superior off-road clearance. Designed specifically for the 2020–2025 Gladiator with the 3.6L engine, this system delivers a deep, powerful tone thanks to the Outlaw Series muffler.

Constructed from 3.0-inch mandrel-bent 409 stainless steel, the system maintains optimal exhaust flow while offering long-term durability and corrosion resistance. Its dump-style turndown exit eliminates the over-axle tailpipe, dramatically improving departure angle and ground clearance—ideal for rock crawling and off-road environments.

This exhaust system uses factory hanger locations for a straightforward installation and includes all necessary hardware for an at-home setup. Built for performance and longevity, it is backed by Flowmaster’s Lifetime Limited Warranty.
