Construction & Design

This axle-back exhaust system is crafted from premium T409 stainless steel, chosen for its excellent resistance to rust and corrosion under typical driving conditions. The material provides robust protection against environmental factors, although exposure to heavy salt air, winter road chemicals, and extreme conditions may accelerate corrosion and are not covered under warranty unless system failure occurs.

Mandrel bending technology ensures the tubing maintains a consistent diameter through all bends, maximizing exhaust flow and minimizing turbulence. This precision engineering improves engine breathing, which can translate into enhanced power output and durability. The dual rear exit layout not only optimizes exhaust flow but also adds an aggressive, custom look to the rear of your Jeep.

Performance & Sound

The MBRP XP Series Axle-Back system is designed to elevate your Jeep Wrangler’s performance by improving exhaust flow dynamics. This results in increased torque and horsepower, along with lower exhaust gas temperatures that help maintain engine health during demanding driving conditions. The exhaust note is carefully tuned to provide a mellow yet sporty sound that enhances the driving experience without being overly loud or intrusive, making it ideal for both daily driving and off-road adventures.

Installation & Fitment

Installation is simple and hassle-free thanks to the bolt-on design that uses your Jeep’s existing OEM hangers. No cutting, welding, or modifications are necessary, allowing for a secure fit and quick upgrade. This exhaust system fits a wide range of Jeep Wrangler JK models from 2007 through 2018, including the 70th and 75th Anniversary editions, Rubicon, Sahara, Sport, Sport S, Unlimited, and X trims equipped with 3.6L or 3.8L V6 engines.
