The MagnaFlow® Jeep Wrangler Rock Crawler Series™ Cat-Back Performance Exhaust System brings superior boulder-climbing capabilities to your 3.8L Jeep Wrangler with a weight-optimized, dyno-tested, corrosion resistant and durable stainless steel design engineered to closely hug the undercarriage of your rig for improved ground clearance. Exhaust kit 15239 is engineered to produce our powerful, resonant signature exhaust note at Aggressive exterior and Moderate interior sound levels. Extensive 3D scanning was used during the development of this Jeep Wrangler exhaust system to create a direct-fit design, enabling a do-it-yourself installation process. 15239's emissions-legal cat-back design replaces all your rig's exhaust components from the catalytic converter on back with its 2.5in. diameter mandrel bent main piping that passes through 1 Straight-Through mufflers before ending in a Single Straight Driver Side Rear exit. The turndown style tipless exit improves departure angles, allowing for more options when it comes to traversing tricky boulders and other off-road obstacles. Exhaust system 15239 is produced using advanced CNC precision robotic manufacturing techniques and backed by MagnaFlow®'s limited lifetime warranty.

Customer Reviews (4.8 / 5 · 5 reviews)

James ★★★★★

The low-end torque improvement on the trail is exactly what I needed for technical climbs, and the sound is deep but not obnoxious inside the cab. Installation took about an hour with basic tools, and the stainless steel tips look great sticking out from under the bumper.

Riley A. ★★★★★

The weight savings were noticeable right away, and the dyno-tested performance bump gave my Wrangler a real edge on steep climbs. It’s surprisingly quiet at cruising speed for a crawler exhaust.

Claire ★★★★★

Installed this on my rock-crawling rig and the weight savings over the stock muffler are very noticeable on the trail. The tone is deep but not obnoxious during highway cruising, and the dyno-tuned design seems to have freed up a bit of low-end torque for climbing.
