Description
Overview
The Flowmaster Flow FX Cat-Back Exhaust System is engineered to transform the exhaust performance and sound of the 2020-2026 Jeep Gladiator equipped with the 3.6L engine. Built from durable stainless steel, this complete cat-back system replaces the restrictive factory piping with large 3-inch mandrel-bent tubing that promotes smoother, more efficient exhaust flow from the muffler back. Whether you’re chasing a bolder exhaust note or a more purposeful look under your Gladiator, the Flow FX delivers a proven, straight-through design from a name that has defined performance exhaust for decades.
Sound & Performance
At the heart of the system is the Flow FX “straight-through” performance muffler, designed to produce a deep, powerful sound outside the vehicle while keeping a moderate, comfortable tone inside the cab. That balance means you get an aggressive exterior presence without droning out your daily drive. The mandrel-bent tailpipe routes cleanly and exits behind the passenger side rear tire, finished with a large 4.50-inch black ceramic coated exhaust tip embossed with the Flowmaster name for a bold, factory-plus appearance.
