Product Description

The Corsa 21199 Sport Cat-Back Exhaust System is engineered for 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 5.3L V8 and a 147.5" wheelbase. This performance cat-back replaces the factory rear exhaust section with a 3.0" mandrel-bent design that transitions to 2.5" in the tail sections to maximize flow and sound characteristics. Featuring CORSA's patented Reflective Sound Cancellation (RSC®) technology, the 21199 delivers a deep, aggressive exhaust note under acceleration while minimizing annoying in-cab drone at cruising speeds.

Constructed from premium 304 stainless steel with polished twin 4.0" Pro-Series exhaust tips, this Sport Series system adds both performance and visual appeal to your GM truck's rear end. The straight-through muffler design enhances throttle response and promotes improved exhaust flow compared to stock. Installation is straightforward with a direct bolt-on design and included hardware - no cutting or welding needed. Ideal for owners seeking a bold yet refined exhaust upgrade with dependable durability and strong sound presence.
