Construction & Design

Crafted from premium stainless steel, the JBA Axle-Back Exhaust System is built to withstand the rigors of daily driving and harsh weather conditions. The mandrel-bent tubing ensures smooth bends that preserve exhaust gas velocity and minimize turbulence, which contributes to improved engine performance. The high-flow mufflers are engineered to provide an aggressive yet refined exhaust note, avoiding the harshness or drone often associated with aftermarket systems.

The polished chrome tips not only enhance the visual appeal of your Durango but also resist discoloration and corrosion. Factory-style hangers and mounting points ensure that the system fits precisely without the need for modifications, preserving the integrity of your vehicle’s undercarriage.
