CORSA Sport 3.0" Cat-Back Exhaust with Polished 4.0" Twin Tips (21126) - 2021-2026 Chevrolet Suburban 5.3L V8
Upgrade your 2021-2026 Chevrolet Suburban 5.3L V8 with the CORSA Performance Sport Cat-Back Exhaust System. Featuring 3.0" 304 stainless steel construction, a straight-through muffler design, and twin polished 4.0" Pro-Series exhaust tips, this system delivers an aggressive exhaust note under acceleration while maintaining a quiet, drone-free cabin at cruising speeds.
Developed by the originators of No Drone Exhaust Technology, this system incorporates CORSA's exclusive Reflective Sound Cancellation (RSC) Technology. CORSA's acoustic engineers use this technology to eliminate unwanted drone-inducing frequencies while producing an aggressive exhaust sound tailored to GM SUVs.
By eliminating the restrictive flow-operated valves found in the factory exhaust system, CORSA allows exhaust gases to flow more freely. CORSA reports horsepower and torque improvements of up to 20% under the curve, along with improved fuel economy. These performance results were recorded on a torque-limited vehicle and do not represent peak horsepower or torque gains.
This Sport cat-back exhaust features polished stainless steel Pro-Series tips with a dual-wall slash-cut design. CORSA's exhaust lineup for GM SUVs also offers multiple exhaust tip and exit configurations.
