It uses 2.75 inch tubing into the muffler with dual 2.75 inch outlets and exits through 4.25 inch intercooled T-304 stainless steel tips finished in a durable high-temperature Ceramic Black coating, with polished T-304 tips also available. ATAK (Acoustically-Tuned Applied Kinetics) tuning calibrates the internal muffler cores for an uncompromising note while limiting in-cabin resonance. It fits all C7 models except the Grand Sport with manual transmission. The system uses Borla's patented straight-through, multi-core design and is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC manufacturing for an accurate fit. Borla exhaust is handmade in the USA. The system is covered by the Borla Million-Mile Warranty for non-moving parts; the exhaust valves are warrantied for one year, and failures of original equipment AFM and NPP actuators are not covered.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSystem type: axle-back\u003c\/li\u003e\n\u003cli\u003eSound level: ATAK, Borla's most aggressive\u003c\/li\u003e\n\u003cli\u003eValves: includes AFM and NPP valves\u003c\/li\u003e\n\u003cli\u003ePiping: 2.75 in to muffler, dual 2.75 in out\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 austenitic stainless steel\u003c\/li\u003e\n\u003cli\u003eConstruction: patented straight-through multi-core, mandrel-bent, CNC manufactured\u003c\/li\u003e\n\u003cli\u003eTips: 4.25 in intercooled T-304 stainless steel, high-temperature Ceramic Black finish (polished available)\u003c\/li\u003e\n\u003cli\u003eFits all C7 models except Grand Sport with manual transmission\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 11856CB\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2014 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2015 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2016 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2017 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2018 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2019 Chevrolet Corvette\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does the Borla 11856CB fit?\u003c\/h5\u003e\u003cp\u003eIt fits the 2014 through 2019 Chevrolet Corvette C7 with the 6.2L V8, including Stingray, Grand Sport, Z06, and ZR1, except the Grand Sport with manual transmission.
