Construction & Design

This exhaust system is crafted from premium stainless steel, chosen for its excellent resistance to rust and corrosion, making it ideal for the rigors of off-road use. The mandrel-bent tubing maintains a smooth internal diameter through bends, maximizing exhaust flow and minimizing backpressure. The design was refined using 3D scanning technology to ensure a perfect fit that contours closely to the Jeep’s undercarriage, reducing the risk of damage and improving clearance when navigating obstacles.

Robotic CNC manufacturing processes guarantee precise welds and consistent build quality, while the tipless turndown exit enhances departure angles, a critical feature for rock crawling and trail driving.

Performance & Sound

The MagnaFlow Rock Crawler Series exhaust system improves your Jeep’s performance by enhancing exhaust flow and reducing backpressure. This results in a more responsive throttle feel and a subtle increase in power delivery without compromising reliability. The system produces MagnaFlow’s distinctive exhaust tone—aggressive and resonant on the outside to announce your presence on the trail, yet moderate enough inside the cabin to maintain comfort during daily driving.
