The Borla axle-back exhaust for the 2014-2019 Chevrolet Corvette C7 6.2L delivers the brand's most aggressive ATAK sound level and includes both AFM and NPP valves. 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.
