Description
CORSA Sport 3.5" Cat-Back Exhaust System with 4.0" Twin Pro-Series Tips | Fits 2021–2025 Chevrolet Suburban, GMC Yukon & Yukon Denali XL 6.2L V8 (Dual Rear Exit)
Experience the perfect blend of performance, sound, and comfort with the CORSA Performance 3.5" Cat-Back Exhaust System, engineered for the 2021–2025 Chevrolet Suburban, GMC Yukon XL, and Yukon Denali XL equipped with the 6.2L V8 and dual rear exit exhaust configuration.
Developed by the leaders in No Drone Exhaust Technology, this system incorporates CORSA’s exclusive Reflective Sound Cancellation® (RSC®) — delivering an aggressive exhaust note under acceleration while maintaining a drone-free cabin at cruising speeds. Designed by acoustic engineers specifically for GM’s flagship SUVs, this system transforms your driving experience without compromising comfort or refinement.
Constructed from premium 304 stainless steel, this 3.5" cat-back system features a straight-through muffler design, optimized exhaust flow, and a dual rear exit (DRE) configuration with twin 4.0" polished Pro-Series tips (available in polished or black). The result is a +20% increase in horsepower and torque under the curve*, improved throttle response, and enhanced fuel efficiency.
CORSA’s attention to detail ensures precise fitment and long-lasting durability. Vehicles originally equipped with a single-side exit exhaust will require specific OEM parts (listed below) to complete conversion to a dual rear exit configuration.
*Performance results measured under the curve. Torque may be limited by factory programming.
