Corsa 20-25 Corvette C8 3in Valved Cat-Back 4.5in Pol Quad Tips Fits Factory Perf Exhaust DeletesAFM
The Corsa 21103 3-inch Valved Cat-Back Exhaust with 4.5-inch Polished Quad Tips establishes the pinnacle of tunable performance and sound control for 2020–2025 Chevrolet Corvette C8 Stingray models equipped with factory NPP, delivering dyno-proven +18 hp and +16 lb-ft torque gains through mandrel-bent 304 stainless steel construction that maximizes flow while retaining dual NPP valves for seamless volume adjustment without drone or CEL, outperforming restrictive OEM setups or non-valved aftermarket systems in throttle response and exhaust harmony. Designed to delete the stock AFM valve while preserving actuator integration, this system offers Xtreme sound levels that roar aggressively under full throttle yet whisper quietly in touring mode, with RSC No Drone Technology ensuring cabin comfort during highway cruises or city drives. The quad polished tips and cast valve assemblies handle the mid-engine layout's heat demands, providing enthusiasts a bolt-on upgrade that enhances the LT2 V8's character across rev ranges better than pieced-together components from other sources.
