Product Description

Transform the sound and exhaust flow of your Cadillac CT4-V Blackwing with the CORSA Xtreme Valved 3.0" Cat-Back Exhaust System. Engineered specifically around the Blackwing's 3.6L twin-turbo V6, 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 directly with the factory Cadillac Active Exhaust valve assembly, allowing the vehicle's drive modes to continue controlling exhaust volume. Keep the car more refined when cruising, then select a more aggressive drive mode to open the valves and unleash considerably more sound.

CORSA's 3.0-inch Double X-Pipe also eliminates the crushed factory piping near the rear axles, providing a less restrictive exhaust path. CORSA reports a 10% increase in exhaust flow and sound levels up to 7 dB louder than stock.

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

Product Features

  • 3.0" Double X-Pipe – Replaces the crushed factory piping near the rear axles and improves exhaust-gas crossover and flow.

  • 10% Increased Exhaust Flow – CORSA reports a 10% improvement in flow compared with the stock exhaust system.

  • Up to 7 dB Louder Than Stock – Provides a noticeable increase in exhaust volume while the active-valve design retains the ability to quiet the system when desired.

  • Four Premium Tip Options – Choose from Polished Stainless Steel, Black PVD, Polished Carbon Fiber, or Black Carbon Fiber to tailor the exhaust to the appearance of your Blackwing.

Why Upgrade?

The CT4-V Blackwing is an exceptionally capable performance sedan, but its factory exhaust leaves room for considerably more sound and character from the 3.6L twin-turbo V6. At the same time, completely eliminating the factory valves would sacrifice one of the car's best features: the ability to change its personality depending on how and where you're driving.

The CORSA Xtreme Valved Cat-Back gives you both.

CORSA retains the factory Active Exhaust controls while expanding the aggressive end of the system's sound range. Select a quieter drive mode for commuting or highway driving, then switch modes and open the valves when you want to hear substantially more of the twin-turbo V6.

The upgrade goes beyond sound. CORSA's complete cat-back incorporates a 3.0-inch Double X-Pipe that eliminates the factory crushed piping near the rear axle, creating a less restrictive exhaust path. CORSA reports a 10% increase in exhaust flow over the stock system.

You can also tailor the appearance to the car. Polished Stainless Steel provides the classic performance look, Black PVD creates a darker OEM+ appearance, Polished Carbon Fiber adds an exotic motorsport-inspired finish, and Black Carbon Fiber provides the stealthiest option.

For CT4-V Blackwing owners who want more than an axle-back, this complete system combines more sound, improved flow, factory valve integration, No Drone technology, a Double X-Pipe, and four premium tip choices in one package.

Give your CT4-V Blackwing the aggressive sound it deserves without sacrificing the factory Active Exhaust control that makes it such a versatile performance sedan.
