This CORSA Performance cat-back exhaust gives the Cadillac CT5-V the sound it deserves while integrating flawlessly with the factory Active Exhaust valve assembly for full control over the driving experience. Tuned with CORSA's No Drone RSC Technology, it creates an aggressive note that runs over 5dB louder than stock yet stays drone free at cruise regardless of valve position. The system features a 3.0in double X-pipe that replaces the restrictive stock crushed piping near the rear axles to increase flow, flowing 10% better than stock. It is constructed from 304 stainless steel with dual-wall 4.5in carbon fiber tips. Engineered and manufactured in the USA and backed by a Limited Lifetime Warranty.
