Construction & Design

The MBRP Cat Back Exhaust System is crafted from T304 stainless steel, the industry’s leading material for exhaust applications. This grade of stainless steel offers superior resistance to rust and corrosion, making it ideal for vehicles exposed to harsh environments such as winter salt or off-road debris. The 3-inch tubing diameter is carefully selected to optimize exhaust gas flow, reducing backpressure and enhancing engine efficiency.

Each component is precision-engineered and mandrel-bent to maintain smooth airflow and ensure a perfect fit. The dual rear exit design not only improves exhaust scavenging but also adds a visually aggressive stance to the rear of your vehicle. The welds are clean and robust, reflecting MBRP’s commitment to quality craftsmanship.

The Street Profile sound tuning strikes a perfect balance between performance and comfort. When accelerating, the exhaust produces a rich, aggressive tone that enhances the driving experience without becoming intrusive during cruising or highway driving. This makes it an excellent choice for daily drivers who want a performance edge without sacrificing refinement.

By improving exhaust flow, this system can help your 5.7L Hemi breathe more efficiently, potentially aiding throttle response and overall engine performance. The dual rear exit layout also contributes to a more balanced and fuller exhaust note.
