Product Description

The CORSA 21129 Sport Cat-Back Exhaust System is engineered specifically for 2021-2025 full-size GM SUVs equipped with the 6.2L V8 engine, including the Chevrolet Tahoe and GMC Yukon (including Yukon Denali). Designed with a mandrel-bent 3.5" to 2.75" piping layout and a dual rear exit, this performance exhaust delivers a robust, aggressive sport sound under acceleration while minimizing unwanted drone at cruising speeds thanks to CORSA's patented Reflective Sound Cancellation (RSC) technology.

Constructed from premium 304 stainless steel, the 21129 system enhances exhaust flow compared to the stock system and improves overall throttle response. The polished twin 4.0" Pro-Series tips not only upgrade the rear styling but also maintain durable performance under daily driving conditions. Installation is straightforward with a bolt-on design using the vehicle's stock hangers and included hardware, making this a high-quality upgrade for owners seeking improved performance, sound, and style from their GM SUV's exhaust system.
