Xtreme to Sport Active Sound
The CORSA 21317CF combines the aggressive sound of an Xtreme system with the versatility of the CT4-V Blackwing's factory Active Exhaust. Select the preferred driving mode and the exhaust responds accordingly, allowing the system to quiet down when desired or open up for a more aggressive performance sound. This preserves the Blackwing's factory-controlled exhaust functionality while giving the 3.6L Twin Turbo V6 a more commanding CORSA exhaust note.
Factory Active Exhaust Integration
CORSA engineered the 21317CF Cat-Back to integrate with the stock Cadillac Active Exhaust valve assembly and retain the vehicle's Dual Mode NPP functionality. The driver can continue using the factory driving modes to control the exhaust experience while benefiting from the upgraded CORSA Cat-Back system.
The factory Active Exhaust Module is required for installation and must be retained for proper operation.
No Drone RSC® Technology
CORSA's No Drone RSC® Technology has been custom tuned specifically around the Cadillac CT4-V Blackwing's 3.6L Twin Turbo V6. The system is engineered to deliver an aggressive performance tone when desired while controlling unwanted exhaust drone during cruising.
3.0-Inch Double X-Pipe
A key feature of the CORSA Cat-Back system is its 3.0-inch double X-pipe. This design eliminates the stock crushed piping found near the rear axles, creating a less restrictive exhaust path that helps increase exhaust flow and performance while contributing to the system's distinctive sound.
4.5-Inch Polished Carbon Fiber Twin Tips
The dual rear exit system is finished with twin carbon fiber tips on each side for an aggressive four-tip layout. Each 4.5-inch tip features a dual-wall straight-cut design with a polished finish, combining carbon fiber styling with premium detailing that complements the performance-focused appearance of the CT4-V Blackwing.
