Construction & Design

The JBA Cat-Back Exhaust System is crafted from premium stainless steel, ensuring excellent resistance to rust and corrosion even under harsh driving conditions. The mandrel-bent tubing preserves consistent diameter throughout bends, minimizing flow restrictions and maximizing exhaust scavenging.

Polished chrome tips add a refined finishing touch that complements the Challenger’s bold styling.
