Corsa Xtreme Valved 3.0-Inch Cat-Back Exhaust System with Double X-Pipe and Twin 4.5-Inch Carbon Fiber Tips for 2022-2025 Cadillac CT5-V Blackwing
The Corsa Xtreme Valved 3.0-Inch Cat-Back Exhaust System. This bolt-on upgrade replaces the factory cat-back section from the catalytic converters rearward, delivering a deep, aggressive rumble that matches the 6.2L LT4 V8's 668 horsepower and 659 lb-ft of torque. Designed exclusively for the Cadillac CT5-V Blackwing, it connects directly to the stock active exhaust valves for seamless control via the vehicle's drive modes switch from refined touring to full-throttle roar without compromise.
Vehicle Fitment Details
- Make: Cadillac
- Model: CT5-V Blackwing
- Years: 2022, 2023, 2024, 2025
- Engine: 6.2L LT4 Supercharged V8
- Body Style: Sedan (RWD/AWD configurations supported)
Notes: Direct fit no modifications required. Retains factory active exhaust functionality and OBD-II compliance. Not compatible with aftermarket cats or non-Blackwing CT5-V models.
This system stands out among exhaust options for the CT5-V Blackwing by addressing common limitations in competitors: it eliminates the stock crushed piping near the rear axles with a patented double X-pipe design that boosts exhaust scavenging for better mid-range torque and throttle response. Dyno testing shows gains of up to 12 horsepower and 15 lb-ft of torque at the wheels compared to stock, while maintaining even backpressure for consistent power delivery across the rev range.
Users report a 15+ dB increase in volume over OEM in Xtreme mode, creating a signature LT4 growl without cabin drone on highways thanks to Corsa's Reflective Sound Cancellation (RSC) Technology that targets and cancels frequencies between 200-700 Hz.
