Corsa Xtreme Valved 3.0" Cat-Back Exhaust with 4.5" Black Carbon Fiber Twin Tips (21326CFBLK) - 2020-2026 Cadillac CT5-V 3.0L
Give your Cadillac CT5-V a more aggressive exhaust note while retaining full factory control with the Corsa Performance Xtreme Valved 3.0-inch Cat-Back Exhaust System. Designed for 2020-2026 Cadillac CT5-V models equipped with the 3.0L Turbo engine and factory Active Valve Exhaust, this system integrates with the OEM exhaust valve assembly so the vehicle's selectable drive modes continue to control exhaust volume and character.
Corsa combines its RSC® (Reflective Sound Cancellation) technology with a 3.0-inch Double X-Pipe to create a strong performance tone while minimizing unwanted cruising drone. The Double X-Pipe replaces restrictive crushed factory piping near the rear axles, helping improve exhaust flow and performance. Twin 4.5-inch black carbon fiber tips finish the system with a dark, premium motorsport-inspired appearance.

Factory Active Exhaust Integration
The Corsa 21326CFBLK is engineered to work with the CT5-V's factory Active Valve Exhaust system. The factory Active Exhaust Module is reused during installation, allowing the exhaust valves to continue responding to the vehicle's selectable drive modes.
This gives you the flexibility to keep the car quieter and more refined when desired, then open the system up for a more aggressive exhaust character when you want the full Corsa performance experience.
Xtreme to Sport Active Sound
The active valve configuration provides a broad sound range based on valve position. With the valves opened, the system delivers Corsa's aggressive Xtreme character. In quieter drive modes, the exhaust settles into a more restrained Sport-oriented tone for everyday driving.
RSC® No-Drone Technology
Corsa's RSC® technology is tuned specifically for the Cadillac 3.0L Turbo engine to target the frequencies responsible for interior drone. This allows the exhaust to deliver a deep, aggressive tone under acceleration while maintaining a more comfortable cabin during steady-speed cruising.
3.0-Inch Double X-Pipe
The system incorporates Corsa's 3.0-inch Double X-Pipe, which crosses the exhaust streams twice to improve flow dynamics and help refine the exhaust note. It also eliminates the crushed factory piping located near the rear axles, creating a freer-flowing path designed to support improved exhaust performance.
4.5-Inch Black Carbon Fiber Twin Tips
The 21326CFBLK configuration is finished with twin 4.5-inch black carbon fiber exhaust tips. Their dual-wall, straight-cut construction provides a substantial performance appearance, while the dark carbon fiber finish gives the rear of the CT5-V a more aggressive and distinctive look.
