The Corsa Performance COR21070BLK delivers the full active valve Xtreme experience for the 2015-2021 Dodge Challenger SRT and Hellcat variants with a bold blacked-out finish. The valve opens for unbridled, roaring V8 sound at wide-open throttle, while the refined mode keeps the Challenger comfortable at cruise. Corsa's patented RSC Technology manages drone in both positions. The system routes through 2.75-inch mandrel-bent T304 stainless steel and exits through twin black PVD 3.5-inch Pro-Series tips for a stealthy, aggressive rear appearance. Like all Corsa systems, COR21070BLK is bolt-on with no tune required and carries a limited lifetime warranty made in the USA.

Frequently Asked Questions
Will this CORSA product fit my 2015-2018 Dodge Challenger?
That vehicle range is listed, but confirm the exact manufacturer part number, trim, cab or body style, factory exhaust or intake configuration, and every application note before ordering.
How should I choose the correct CORSA exhaust configuration?
Compare sound level, pipe diameter, exit location, tip finish, factory valve or active-exhaust requirements, cab and bed or body configuration, and the exact part number.
Does this CORSA exhaust require professional installation?
Vehicle-specific systems are generally bolt-on when the exact application matches. Universal components can require cutting and welding. Professional installation helps ensure alignment, clearance, sealing, and correct clamp torque.
Installation Instructions
Follow CORSA and vehicle service instructions. Support the vehicle safely, allow the exhaust to cool, verify all hangers and clearances, align the system before final tightening, check for leaks, and recheck clamp torque after the first heat cycle.
