Product Description:
Hawks Motorsports offers our clients this 11863 2014-2019 Chevrolet Corvette Stingray C7 ATAK Axle-Back Exhaust System with AFM Valves, Borla. This 2.75-inch axle-back system is built from T-304 stainless steel and is designed for C7 Corvettes equipped with AFM valves but without factory NPP valves. It features Borla's ATAK sound, quad center-rear exhaust outlets, and four 4.25-inch polished intercooled tips.
For a C7 that needs more attitude out back, the ATAK system brings a noticeably more aggressive exhaust character without replacing the entire exhaust. It bolts into the rear section of the factory system and keeps the AFM hardware in the mix. The big thing to get right before ordering is the valve configuration—11863 is specifically for cars without NPP.
If you're building a C7 around an axle-back setup and want to go further later, Borla lists X-Pipe 60548 as the companion component for converting the setup to a complete cat-back system.
