Construction & Design

This axle-back exhaust system is constructed from heavy-gauge aluminized steel tubing, chosen for its excellent resistance to heat and corrosion. The main tubing features a mill-finish steel surface designed to withstand undercarriage impacts, while the tailpipes and tips are finished with a high-heat black powder coat that resists fading, chipping, and rust.

Mandrel bending technology is applied throughout the tubing to maintain a consistent diameter and smooth airflow, eliminating ripples or sharp bends that can restrict exhaust gases. The dual rear exit layout not only enhances the Jeep’s aggressive stance but also optimizes exhaust scavenging, improving engine efficiency and performance. Fully sealed seams protect against moisture intrusion, ensuring long-term durability.

Performance & Sound

The MBRP Black Series Axle-Back Exhaust is designed to improve your Jeep Wrangler’s performance by increasing exhaust flow and reducing backpressure. This results in noticeable gains in torque and horsepower, along with a more responsive throttle. Additionally, the system helps lower exhaust gas temperatures, which can contribute to improved engine longevity.

The exhaust note is carefully tuned to deliver a mellow yet commanding sound that enhances the driving experience without being overly loud or intrusive. This makes it an excellent choice for daily drivers who want a performance upgrade that remains comfortable on and off the road.

Installation & Fitment

Installation is straightforward and hassle-free, utilizing your Jeep’s existing OEM hangers and mounting points. No cutting, welding, or modifications are necessary, making this axle-back exhaust a true bolt-on upgrade. It fits a wide range of Jeep Wrangler JK models from 2007 to 2018, including popular trims such as the 70th and 75th Anniversary editions, Rubicon, Sahara, Sport, Sport S, and Unlimited variants.
