Flowmaster introduces our FlowFX Extreme stainless steel cat-back exhaust system for the 2020-2021 Jeep Gladiator JT with the 3.6L engine. This system uses a FlowFX series muffler for a deep powerful sound and increased performance. 3.0-inch mandrel bent 409 stainless steel tubing is used for maximum exhaust flow and durability. The system has a turndown style dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps to improve ground clearance and departure angle when you are driving in more extreme off-road situations. All of the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
