Corsa Xtreme Valved Catback Cadillac CT5-V Blackwing

Unleash the sound of the Cadillac CT5-V Blackwing's supercharged 6.2L LT4 with the CORSA Xtreme Valved 3.0" Cat-Back Exhaust System. Engineered specifically for the Blackwing, this complete cat-back combines CORSA's aggressive Xtreme-to-Sport Active sound profile, factory Active Exhaust integration, No Drone RSC® technology, and a high-flow 3.0-inch Double X-Pipe.

The system integrates with the factory Cadillac Active Exhaust valve assembly, allowing the vehicle's drive modes to continue controlling exhaust volume. Keep the Blackwing more refined when cruising or open the valves and let the LT4 deliver the aggressive V8 sound it deserves.

CORSA's 3.0-inch Double X-Pipe replaces the restrictive factory piping near the rear axles while improving exhaust flow and scavenging. CORSA reports a 12% increase in exhaust flow and sound levels up to 15 dB louder than stock.

Complete the system with your choice of four distinct 4.5-inch tip configurations: Polished Stainless Steel, Black PVD, Polished Carbon Fiber, or Black Carbon Fiber.

Why Upgrade?

The CT5-V Blackwing combines a 668-horsepower supercharged LT4 with the refinement of a luxury sport sedan, and its factory Active Exhaust system is a major part of that versatility. A performance exhaust shouldn't force you to give that up.

The CORSA Xtreme Valved Cat-Back retains the factory valve functionality while dramatically expanding the aggressive side of the Blackwing's personality. When you want a more restrained exhaust note, the valves allow the system to quiet down. Switch to a more aggressive setting and the CORSA system lets the supercharged V8 come alive.

CORSA also addresses more than sound. The complete cat-back incorporates a full 3.0-inch Double X-Pipe that eliminates the factory crushed sections near the rear axle, providing a less restrictive exhaust path and improved scavenging. The result is a system CORSA rates at 12% more flow than stock.

The four available tip configurations make it easy to tailor the appearance to the car. Polished Stainless Steel provides a classic performance look, Black PVD delivers a stealthier OEM+ appearance, Polished Carbon Fiber adds a premium motorsport aesthetic, and Black Carbon Fiber provides the darkest and most aggressive finish.

For Blackwing owners who want the complete package rather than simply an axle-back, the CORSA Xtreme Valved Cat-Back combines more sound, improved flow, a Double X-Pipe, factory valve integration, No Drone technology, and four premium tip choices in one system.

Let the Blackwing's supercharged LT4 sound the way it should without sacrificing factory Active Exhaust control—CORSA Xtreme when you want it, refined when you don't.
