Product Description:
Hawks Motorsports offers our clients this 11856 2014-2019 Chevrolet Corvette Stingray C7 ATAK Axle-Back Exhaust System with AFM & NPP Valves, Borla. This axle-back system is built for C7 Corvette Stingray models equipped with factory AFM and NPP dual-mode exhaust. It uses 2.75-inch tubing, T-304 stainless steel construction, and quad 4.25-inch polished intercooled tips.
The ATAK system is for the C7 owner who wants the car to sound like it means business. It replaces the factory rear muffler and exhaust sections while keeping the active exhaust hardware in the system. You get the aggressive ATAK sound when you're in the throttle, while the NPP valves retain the car's dual-mode exhaust operation. Borla also uses its straight-through and multi-core muffler design for a high-flow rear section without giving up street-driving manners.
This system includes both AFM and NPP valves and is not compatible with Grand Sport models equipped with a manual transmission. Borla's X-Pipe 60548 can be added if you want to turn the axle-back into a complete cat-back system.
