It keeps your drive-mode sound control rather than replacing it. It runs \u003cstrong\u003e9 decibels\u003c\/strong\u003e louder than stock at full throttle and 1 decibel quieter with the valves closed.\u003c\/p\u003e\n\n\u003cp\u003eThe tips are Black PVD, the same Pro-Series tip as the polished version in a dark finish. On a C8 that changes how the back of the car reads. A polished tip catches light and pulls your eye straight to the fascia cutouts; a dark tip sits back into them and lets the diffuser be the shape you notice. Nothing ahead of the tips changes, so the quiet start and the drive-mode control are untouched, and the 1 decibel below stock is still there on a cold morning.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e CORSA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 21100BLK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem type:\u003c\/strong\u003e Cat-back, valved, mufflers retained\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe diameter:\u003c\/strong\u003e 3.0 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTips:\u003c\/strong\u003e Quad, 4.5 inch, two per side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip series:\u003c\/strong\u003e Pro-Series, dual wall slash cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip finish:\u003c\/strong\u003e Black PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound vs stock:\u003c\/strong\u003e 9 decibels louder, 1 decibel quieter, per CORSA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower:\u003c\/strong\u003e 18 hp, per CORSA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque:\u003c\/strong\u003e 16 lb-ft, per CORSA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory NPP:\u003c\/strong\u003e Required.

Four of them, two per side. The finish is in the tip as it is built rather than painted or wrapped over a polished one, and the durability claim attached to it is the manufacturer's and not ours: per CORSA the Black PVD finish enhances the tip's durability and longevity. What you can judge for yourself is what a dark tip does to the back of a C8. A polished mouth catches light and pulls your eye to the fascia cutouts; a black one sits into them. The set is also sold on its own as the CORSA 21109BLK quad tip kit, four tips in one assembly, fitting CORSA exhaust systems only.\u003c\/p\u003e\n\n\u003ch3\u003eImportant Exhaust Notes\u003c\/h3\u003e\n\n\u003cp\u003eA Check Engine Light is the thing C8 owners ask about most before they buy an exhaust, so here is the direct answer. These valve assemblies mate to your factory actuator motors, and that is what keeps the Check Engine Light off when the valves move. Some C8 installs still want the GM valve relearn afterward because of factory build tolerances, and that procedure is GM Document ID 5406413. Your installer will know it. This system is for a Stingray that came with NPP; if your car does not have it, you want a different CORSA part number and we will point you at it.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cspan style=\"color: #ff2a00;\"\u003eCORVETTE COMPATIBILITY\u003c\/span\u003e\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeneration:\u003c\/strong\u003e C8 Corvette\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Stingray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Years:\u003c\/strong\u003e 2020 - 2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e 6.2L LT2 V8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Styles:\u003c\/strong\u003e Coupe and HTC convertible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired Equipment:\u003c\/strong\u003e Factory NPP exhaust\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eUse Overview\u003c\/h3\u003e\n\n\u003cp\u003eUse the CORSA 21100BLK when your Stingray has factory NPP, you want the darker tip against the rear fascia, and you are not willing to trade away the quiet start to get a louder car.
