Give Your CT5-V a Voice That Matches Its Power
The factory active exhaust on the CT5-V is tuned for quiet compliance, leaving the twin turbo V6 sounding muted even in Sport mode. This CORSA Xtreme cat back exhaust replaces the restrictive factory piping with a free flowing 3 inch double X-pipe system and twin 4.5 inch black carbon fiber tips, working directly with the factory active exhaust valve so tone still follows drive mode selection.
Key Features
- 3 inch cat back system with a double X-pipe that eliminates the crushed factory piping sections near the rear axle
- Integrates with the factory Active Exhaust valve module, so drive mode still controls tone
- Patented No Drone Reflective Sound Cancellation technology removes the resonant frequencies that cause interior drone
- Twin 4.5 inch black carbon fiber tips for a finished, aggressive rear appearance
- Constructed from 304 stainless steel for long term corrosion resistance
- Flows up to 10 percent better than the factory system for improved throttle response
- Engineered and manufactured in the USA

FAQ
What is the 21326CFBLK?
The 21326CFBLK is a CORSA Xtreme 3 inch cat back exhaust system for the 2020 and newer Cadillac CT5-V, featuring a double X-pipe and twin 4.5 inch black carbon fiber tips. It works with the factory Active Exhaust valve to preserve drive mode tone control.
Does this fit the Cadillac CT5-V Blackwing?
No. This system is designed for the standard CT5-V and is not the same part used on the CT5-V Blackwing, which uses its own dedicated CORSA part number.
Does this exhaust require the factory Active Exhaust valve module?
Yes. The 21326CFBLK is built to work with the factory Active Exhaust module, so the vehicle retains drive mode based tone control after installation.
Will installing this exhaust cause any cabin drone?
CORSA's No Drone Reflective Sound Cancellation technology is engineered specifically to remove the resonant frequencies that typically cause interior drone at highway cruising speeds.
What modifications are needed to install this system?
Installation requires removing the OEM exhaust tip bezel and trimming a small section of the rear underpaneling to clear the new carbon fiber tips.
What is the warranty on this exhaust system?
The system carries a limited lifetime warranty against manufacturing defects, with the active exhaust valve components covered for 5 years.
How much of a performance gain does this exhaust provide?
CORSA reports up to a 10 percent flow improvement over the restrictive factory system, which helps improve throttle response.

The system is constructed from 304 stainless steel for long term durability and corrosion resistance in all climates.
