Construction & Design

The MBRP S7103AL exhaust system is expertly crafted from aluminized steel, which offers excellent resistance to rust and corrosion while providing a cost-effective alternative to stainless steel. The use of mandrel bending technology ensures smooth, consistent bends that preserve the diameter of the tubing throughout the system. This design minimizes flow restrictions and optimizes exhaust gas evacuation, contributing to improved engine efficiency and throttle response.

Every component is manufactured using precise jig fixtures, guaranteeing that each pipe and weld aligns perfectly with the factory mounting points. This attention to detail results in a seamless fitment that integrates flawlessly with your Challenger’s existing exhaust layout. The dual split rear exit not only enhances the visual appeal but also improves exhaust flow dynamics, delivering a deep, aggressive tone that is unmistakably MBRP.

Performance & Sound

The MBRP cat-back system is engineered to unlock your Dodge Challenger’s true potential by improving exhaust flow and reducing backpressure. Removing the factory exhaust valves allows for a freer-flowing exhaust path, which can contribute to a more responsive throttle and a slight performance gain. The 3-inch tubing diameter and dual split design create a bold, deep muscle car exhaust note that commands attention without being overly loud or droning during highway cruising.

This exhaust system strikes the perfect balance between aggressive sound and daily drivability, making it suitable for street use while delivering the iconic MBRP Street Profile tone that muscle car enthusiasts desire.

Installation & Fitment

Installation of the MBRP S7103AL cat-back exhaust system is straightforward thanks to its bolt-on design. The system is engineered to fit directly onto the factory exhaust hangers and flanges without the need for cutting, welding, or additional modifications. This allows for a quick and clean installation process that can typically be completed with basic hand tools.

The system is specifically designed to fit 2015–2023 Dodge Challenger models equipped with 5.7L HEMI, 6.2L Hellcat, and 6.4L 392 engines, ensuring a perfect match and reliable performance. Retaining the factory exhaust tips means the exterior appearance remains OEM, preserving the classic Challenger look while upgrading the sound and performance behind the scenes.
