CORSA Xtreme Valved 3" Cat-Back Exhaust with Polished 4.5" Slash-Cut Tips (21317) - 2022-2026 Cadillac CT4-V Blackwing 3.6L
Give your Cadillac CT4-V Blackwing the aggressive exhaust note and increased-flow exhaust path it deserves with the CORSA Xtreme Valved 3.0-Inch Cat-Back Exhaust System. Engineered specifically for the 2022-2026 Cadillac CT4-V Blackwing 3.6L Twin Turbo V6, this system integrates with the factory Cadillac Active Exhaust valve assembly to retain driver control over the exhaust experience while adding CORSA's Xtreme to Sport Active sound range.
Unlike an Axle-Back upgrade, the CORSA Cat-Back incorporates a 3.0-inch double X-pipe that eliminates the factory crushed piping near the rear axles, helping increase exhaust flow and performance. CORSA combines the freer-flowing design with its No Drone RSC® Technology, custom tuned specifically for the Cadillac 3.6L Twin Turbo V6.

Xtreme to Sport Active Sound
The CORSA 21317 combines an aggressive Xtreme sound with the versatility of the CT4-V Blackwing's factory Active Exhaust system. Simply select the preferred driving mode and the exhaust responds accordingly, allowing the system to quiet down when desired or open up to unleash a more aggressive exhaust note. This preserves the functionality that makes the Blackwing's active exhaust so versatile while giving the 3.6L Twin Turbo V6 a more commanding CORSA sound.
Factory Active Exhaust Integration
CORSA engineered this Cat-Back to integrate with the stock Cadillac Active Exhaust valve assembly rather than eliminating the factory valve functionality. The driver can continue using the vehicle's 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 the aggressive performance sound enthusiasts want while controlling unwanted exhaust drone during cruising.
3.0-Inch Double X-Pipe
A key advantage 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 characteristics.
Twin 4.5-Inch Polished Pro-Series Tips
The dual rear exit exhaust is finished with twin polished Pro-Series tips on each side, creating an aggressive quad-tip layout at the rear of the CT4-V Blackwing. Each 4.5-inch tip features CORSA's dual-wall slash-cut design and polished finish for a clean, premium appearance.
