Corsa Xtreme Valved 3.0" Cat-Back Exhaust with 4.5" Polished Tips (21326) - 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 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 deliver a powerful performance tone while minimizing unwanted cabin drone. The Double X-Pipe also replaces restrictive crushed sections of the factory exhaust near the rear axles, helping improve exhaust flow and overall performance. Twin 4.5-inch polished tips complete the system with a premium performance appearance.

Factory Active Exhaust Integration
The Corsa 21326 is engineered to work with the CT5-V's factory Active Valve Exhaust system. The factory Active Exhaust Module is required for installation, allowing the exhaust valves to continue responding to the vehicle's drive modes.
This means you can retain a quieter, more refined exhaust setting when desired and open the valves for a more aggressive Xtreme sound when you want the full performance experience.
Xtreme to Sport Active Sound
With the valves open, the system delivers Corsa's aggressive Xtreme exhaust character. In quieter drive settings, the active valves reduce exhaust volume for a more refined tone. This gives the CT5-V a broad range of sound without sacrificing the flexibility of the factory active exhaust system.
RSC® No-Drone Technology
Corsa's RSC® technology is tuned specifically for the Cadillac 3.0L Turbo engine to target undesirable frequencies responsible for interior drone. The result is a strong performance exhaust note under acceleration while maintaining a comfortable cabin during steady-speed cruising.
3.0-Inch Double X-Pipe
The Cat-Back system incorporates Corsa's 3.0-inch Double X-Pipe, which crosses the exhaust streams twice to improve exhaust flow dynamics and refine the overall sound. It also eliminates the crushed factory piping located near the rear axles, creating a freer-flowing exhaust path designed to support improved performance.
4.5-Inch Polished Tips
The 21326 configuration is finished with twin 4.5-inch polished exhaust tips. Their dual-wall, straight-cut construction provides a clean, premium appearance that complements the performance-focused design of the CT5-V.
