Construction & Design

The MagnaFlow Rock Crawler Series exhaust system is crafted from premium stainless steel, providing superior resistance to rust and corrosion even under the harshest off-road conditions. Mandrel bent piping maintains a consistent diameter throughout bends, reducing turbulence and enhancing exhaust gas flow for improved engine efficiency and throttle response.

Each component is CNC-machined to exact specifications, ensuring a perfect fit on your Jeep Wrangler Rubicon 392. The dual exit design not only adds an aggressive visual element but also improves ground clearance and departure angles, critical for serious off-road excursions.

Performance & Sound

Dyno-proven to deliver performance gains, this exhaust system reduces backpressure and improves exhaust scavenging. The straight-through mufflers and 3-inch piping optimize flow, allowing your 6.4L HEMI V8 to breathe more freely. This results in a more responsive throttle and enhanced engine efficiency.

The exhaust note is carefully tuned to provide a deep, throaty growl that commands attention without excessive cabin drone. Thanks to the integrated No Drone Technology resonator, long highway drives remain comfortable without fatigue caused by constant exhaust noise.
