Product Description

The Corsa 21317BLK is a premium valved cat-back exhaust system developed specifically for the 2022-25 Cadillac CT4-V Blackwing. Designed around Corsa's advanced RSC® technology, this system delivers a refined, aggressive tone under throttle while reducing unwanted resonance at cruising speeds.

Featuring dual-mode active valves, the exhaust allows you to switch between a quieter "Sport" mode and a louder "Xtreme" mode seamlessly - giving you control over your driving experience. The 3.0" double X-pipe optimizes flow and enhances sound sculpting, while the 4.5" black PVD slash-cut tips give the rear a sleek, performance look.

Constructed from 304 stainless steel, the system is durable, corrosion-resistant, and engineered for a clean, straight-through bolt-on fitment using the factory active exhaust module. Backed by a limited lifetime warranty, the 21317BLK is a top choice for Blackwing owners who want both style and performance from their exhaust upgrade.
