Description
Upgrade your 2024–2025 Chevrolet Silverado 1500 or GMC Sierra 1500/Denali 6.2L with this CORSA Sport 3.0" Cat-Back Dual-Rear-Exit (DRE) exhaust system. Engineered for drivers who want aggressive exterior sound, improved performance, and factory-integrated appearance, this Cat-Back delivers a throaty, sport-oriented note while retaining excellent on-road refinement.
The system uses mandrel-bent 3.0" main tubing that steps down to 2.5" where required, a straight-through muffler design and precision welds for maximum flow and durability. It includes twin 4.0" polished Pro-Series dual-wall slash-cut tips for a clean OEM-style finish. For vehicles equipped with active valve exhaust systems, a Valve Simulator is included to prevent Check Engine Lights when deleting the factory flow-valve — enabling proper operation and reliable diagnostics after installation.
This Cat-Back is engineered for direct bolt-on installation, provides measurable gains in throttle response and midrange power, and is built from corrosion-resistant stainless steel for long life.
