The MagnaFlow Rock Crawler Series Cat-Back Performance Exhaust System #15238 is engineered to give your 2007–2011 Jeep Wrangler 3.8L superior boulder-climbing capability and off-road performance. Featuring a weight-optimized, dyno-tested, corrosion-resistant stainless steel construction, this system is designed to closely hug the undercarriage for improved ground clearance and obstacle clearance in extreme terrain.
Exhaust system #15238 delivers MagnaFlow’s powerful, resonant signature exhaust tone, producing aggressive exterior sound levels with moderate interior sound levels. Its emissions-legal cat-back design replaces factory exhaust components from the catalytic converter back and utilizes 2.5-inch mandrel-bent main piping flowing through one straight-through muffler.
The system terminates in a single straight driver-side rear exit featuring a tipless turndown design, which improves departure angles and reduces the risk of exhaust damage when navigating rocks, ledges, and other off-road obstacles.
Developed using extensive 3D scanning, this exhaust offers a precise direct-fit design for easy do-it-yourself installation. Manufactured using advanced CNC precision robotic techniques, the system is built from durable stainless steel and backed by MagnaFlow’s limited lifetime warranty.
