Product details
Flowmaster introduces our new Flow FX Extreme stainless steel cat-back exhaust system for the 2018-2026 Jeep Wrangler JL with the 3.6L engine. This system uses a Flow FX 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. Gain up to 12 hp and 13 lbs-ft of torque at the rear wheels. 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.
