Corsa Sport 3.0" Cat-Back Dual Rear Exit Exhaust (21033-1) - 2024-2026 Silverado / Sierra / Sierra Denali 6.2L V8
Upgrade the exhaust sound of your 2024-2026 Chevrolet Silverado, GMC Sierra, or GMC Sierra Denali 6.2L V8 with the Corsa Sport 3.0" Cat-Back Exhaust System. Designed for compatible 147.5" wheelbase trucks, the 21033-1 delivers Corsa's Sport sound through a dual rear exit configuration while retaining the clean, integrated appearance of the factory exhaust bezels.
This updated configuration also includes a valve simulator module for the applicable factory exhaust electronics. The result is a complete Cat-Back upgrade engineered around the newer 6.2L GM truck platform while maintaining the factory-style rear bumper appearance.
Corsa Sport Sound
The Corsa 21033-1 is configured with the Sport sound level, giving the 6.2L V8 a more aggressive exhaust character. It is a performance-focused option for Silverado, Sierra, and Sierra Denali owners who want to enhance the sound of their truck while retaining the factory-integrated exhaust outlets.
3.0" Cat-Back Exhaust System
The 21033-1 is a complete Cat-Back exhaust system featuring a 3.0" pipe diameter configuration that transitions from 3.0" to 2.5". The system replaces the applicable exhaust components behind the catalytic converters and is engineered specifically around compatible 6.2L V8 GM truck applications.
Dual Rear Exit Configuration
Corsa uses a dual rear exit layout that routes the exhaust through the factory locations at the rear of the truck. This configuration preserves the integrated exhaust appearance of properly equipped Silverado, Sierra, and Sierra Denali models while providing the sound upgrade of a Corsa Sport Cat-Back system.
Reuses Factory Exhaust Bezels
The Corsa 21033-1 does not use conventional aftermarket exhaust tips. Instead, it is designed to reuse the factory exhaust bezels incorporated into the truck's rear bumper.
Retaining the factory bezels keeps the exterior appearance clean and OEM-inspired while upgrading the exhaust components behind them. No separate Corsa exhaust tips are included with this system.
Includes Valve Simulator Module
The 21033-1 includes a valve simulator module as part of the exhaust package. This module is supplied for the applicable factory exhaust valve electronics, making it an important component of this updated system for 2024-2026 applications.
Designed for 147.5" Wheelbase GM Trucks
The Corsa 21033-1 is designed around compatible GM trucks with the 147.5" wheelbase. Listed configurations include Crew Cab Short Bed and Double Cab Standard Bed applications depending on the specific Chevrolet Silverado, GMC Sierra, or GMC Sierra Denali model.
Because cab, bed, engine, and wheelbase configurations directly affect exhaust fitment, verify that the vehicle has the required 6.2L V8 and 147.5" wheelbase before ordering.
Max Tow Package Compatible
Corsa states that this exhaust configuration fits compatible vehicles equipped with the Max Tow Package. This fitment information was confirmed by Corsa as of September 14, 2022.
