This system delivers a measured 47 percent increase in exhaust flow over the factory system and is dyno-proven to add 17 horsepower and 16 lb-ft of torque at the rear wheels. Corsa RSC (Reflective Sound Cancellation) technology targets and eliminates the drone frequencies that plague V8 trucks at cruise while delivering an aggressive, authoritative exhaust note at full throttle. The 21033-1 reuses the factory tip bezels for a clean, OEM-look exit, and includes a valve simulator module to maintain proper signal to the factory active exhaust controller. This system is also confirmed compatible with the Max Tow Package. Engineered and manufactured in the USA, backed by Corsa's Lifetime Warranty.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCorsa 21033-1 Sport 3.0-inch

21033-1?\u003c\/strong\u003e\n\u003cp\u003eThe Corsa 21033-1 fits 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 (including Sierra Denali) trucks equipped with the 6.2L V8, in either Double Cab Standard Bed or Crew Cab Short Bed configuration at 147.5-inch wheelbase. Verify your wheelbase and cab\/bed combination before ordering, as Corsa offers separate part numbers for other configurations.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the Corsa 21033-1 work with the factory active exhaust system?\u003c\/strong\u003e\n\u003cp\u003eYes. The 21033-1 includes a valve simulator module that sends the correct signal to the factory active exhaust controller, maintaining full OEM driving mode functionality. No warning lights or error codes result from removing the factory exhaust valve assembly.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat dyno gains can I expect from the Corsa 21033-1?\u003c\/strong\u003e\n\u003cp\u003eCorsa dyno testing shows gains of 17 horsepower and 16 lb-ft of torque at the rear wheels on the 6.2L V8 Silverado\/Sierra. These gains result from the 47 percent flow increase over the stock system, which reduces backpressure and improves exhaust scavenging at higher RPM.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the Corsa 21033-1 come with aftermarket tips?\u003c\/strong\u003e\n\u003cp\u003eNo. The 21033-1 is designed to reuse the factory OEM tip bezels for a clean, integrated appearance that blends with the stock rear bumper cutouts. If you prefer aftermarket tips, Corsa offers other 21033 variants with tip upgrades.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the Corsa 21033-1 compatible with the Max Tow Package?\u003c\/strong\u003e\n\u003cp\u003eYes. As of September 14, 2022, Corsa confirmed that the 21033-1 fits Silverado and Sierra 1500 trucks equipped with the Max Tow Package without modification.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is Corsa RSC technology?\u003c\/strong\u003e\n\u003cp\u003eRSC stands for Reflective Sound Cancellation. Corsa engineers tune each system to identify and cancel the specific frequencies that cause interior drone at highway cruise, without restricting flow or reducing exhaust note under power. The 21033-1 Sport system produces an aggressive V8 rumble under acceleration while staying completely drone-free at steady highway speeds.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the Corsa 21033-1 fit 2024 and 2025 Silverado or Sierra trucks?\u003c\/strong\u003e\n\u003cp\u003eYes. Corsa lists the 21033-1 as compatible with the 2019-2025 model year Silverado 1500 and Sierra 1500 in the specified cab, bed, wheelbase, and engine configuration. Always verify fitment on Corsa's website for the most current model year coverage.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the Corsa 21033-1 require any cutting or modification?\u003c\/strong\u003e\n\u003cp\u003eNo. The 21033-1 is a direct bolt-on replacement for the factory cat-back system. All required hardware is included. The system uses the factory tip bezel openings without any bumper modification.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is Corsa's Lifetime Warranty on the 21033-1?\u003c\/strong\u003e\n\u003cp\u003eCorsa backs all exhaust components with a Lifetime Warranty against defects in materials and workmanship, provided the system is installed per the included instructions and not used in racing or competition applications.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eAllow the factory exhaust to cool completely before beginning.
