Nothing about the rear of the car is left the way it arrived. For an owner who was going to change the tips anyway, doing it in the same part number saves buying a tip kit twice.\u003c\/p\u003e\n\u003cp\u003eBlack chrome sits over T-304 stainless, so the finish is on the same steel the rest of the system is built from and it is not paint on a plated tip. Behind those tips the \u003cstrong\u003e140839BC replaces the exhaust from the catalytic converters back\u003c\/strong\u003e, moving the gas out through 3-inch piping in place of the factory routing, which is a longer run of the car than an axle-back reaches. Committing to the aggressive setting does not cost you the mornings you need the car quiet, because \u003cstrong\u003eAFM\/DFM valves and NPP valves included\u003c\/strong\u003e in the kit connect to the factory actuators. The heat shielding ships with it, so the system arrives complete.\u003c\/p\u003e\n\u003ch3\u003eBorla 140839BC Product Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Borla\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 140839BC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem type:\u003c\/strong\u003e Cat-Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound level:\u003c\/strong\u003e ATAK, Borla's aggressive setting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e C8 Corvette Grand Sport, 6.7L LS6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTips:\u003c\/strong\u003e Four inch round, black chrome on T-304 stainless steel, dual round rolled angle cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExit style:\u003c\/strong\u003e Dual split rear exit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain piping:\u003c\/strong\u003e 3-inch, with 2-inch and 2.75-inch sections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e T-304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValves:\u003c\/strong\u003e AFM\/DFM valves and NPP valves included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping:\u003c\/strong\u003e Two boxes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Borla Million Mile Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAn aggressive exhaust note on a naturally aspirated 6.7-liter V8\u003c\/li\u003e\n\u003cli\u003eCat-back coverage: everything from the catalytic converters back, not only the section behind the axle\u003c\/li\u003e\n\u003cli\u003e3-inch main piping in place of the factory routing\u003c\/li\u003e\n\u003cli\u003eFactory valve behavior kept intact, so aggressive does not mean loud all the time\u003c\/li\u003e\n\u003cli\u003eFour inch black chrome tips across the wide-body rear, dark where the factory outlets sit bright\u003c\/li\u003e\n\u003cli\u003eBlack chrome is applied over T-304 stainless, not over a painted or plated substrate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat to Expect After Installation\u003c\/h3\u003e\n\u003cp\u003eTwo things change and both are immediate. Behind the car the tips read dark where the factory outlets read bright, across a fascia wider than any other C8 wears. At throttle the tone is harder-edged than stock, and with the valves closed the car still behaves the way it did the day you picked it up. There is no published decibel figure for this system and we do not estimate one. Owners who have heard the car both ways are the only real source on that, so if the exact sound is what you are deciding on, call us before you order. A warning light after the install is the valve relearn, and the recalibration step is covered below.\u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eImportant Exhaust Notes\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThis fits the Grand Sport built with the factory NPP valved performance exhaust.\u003c\/strong\u003e Do not install it on a car without O.E.
