Construction & Design

Crafted from premium stainless steel, the JBA Cat-Back Exhaust System is built to withstand the rigors of daily driving and high-performance use. The mandrel-bent tubing ensures smooth bends that maintain consistent diameter throughout the system, minimizing flow restrictions and turbulence. This design maximizes exhaust scavenging and efficiency, which can contribute to improved engine performance.

The system’s mufflers are engineered to balance sound quality with performance gains, providing a deep, aggressive tone without excessive drone inside the cabin. Polished stainless steel tips not only enhance the visual appeal but also resist discoloration and corrosion over time. Factory-style hangers and included hardware make installation straightforward while ensuring a secure, factory-like fit.
