Corsa Sport Valved Axleback Cadillac CT5-V Blackwing

Give your Cadillac CT5-V or CT5-V Blackwing a deeper, more aggressive exhaust note while retaining full control of the factory Active Exhaust system with the CORSA Sport Valved 3.0" Axle-Back Exhaust.

Rather than eliminating the factory valve functionality, CORSA designed this system to integrate with the OEM Cadillac Active Exhaust valve assembly. Select your preferred factory driving mode and the exhaust responds accordingly, transitioning from a more refined cruising tone to a significantly more aggressive performance sound.

CORSA's signature No Drone RSC® Technology is tuned specifically for the Cadillac application to control unwanted cabin resonance while allowing the engine to deliver a stronger exhaust note under acceleration. CORSA reports a 10% increase in exhaust flow and sound levels up to 12 dB louder than stock.

The system features 3.0-inch tubing and quad 4.5-inch dual-wall Pro-Series slash-cut tips, available in your choice of Polished Stainless Steel or Black PVD.

Product Features

• 10% Increased Exhaust Flow – CORSA reports improved exhaust flow compared with the factory system, reducing restriction while maintaining the functionality expected from a luxury performance sedan.

• Up to 12 dB Louder Than Stock – Provides a noticeable increase in exhaust volume and character when the system is opened up.

• Polished or Black PVD Tips – Choose Polished Stainless Steel for a clean OEM+ appearance or Black PVD for a darker, more aggressive look.

Why Upgrade?

The CT5-V—and especially the 668-horsepower supercharged CT5-V Blackwing—deserves more exhaust presence than the factory system provides. At the same time, one of the advantages of Cadillac's Active Exhaust system is the ability to change the character of the car depending on how you're driving.

The CORSA Sport Valved Axle-Back preserves that flexibility. It integrates with the factory valve assembly instead of replacing it, so you don't have to choose between a quiet luxury sedan and an aggressive performance exhaust. Your factory drive modes continue to control the system.

For the CT5-V Blackwing's supercharged LT4, the Sport Valved system brings considerably more V8 character into the driving experience while CORSA's RSC® technology addresses the unwanted resonance that can make a louder exhaust tiring on longer drives. For the 3.0L twin-turbo CT5-V, it provides the same combination of additional sound and factory valve integration.

Finish the system with Polished Stainless Steel 4.5" tips for a clean factory-performance appearance or Black PVD tips for a stealthier look that pairs particularly well with black trim, wheels, and carbon-fiber exterior components.

Give your CT5-V or CT5-V Blackwing the sound it deserves without giving up the factory Active Exhaust functionality that makes it such a versatile performance sedan.
