Unleash the most aggressive sound Borla offers for the C7 Stingray with the Borla ATAK Axle-Back Exhaust System (Part #11881). Engineered specifically for 2014–2019 Corvette Stingray models without the factory NPP performance exhaust, the ATAK (Acoustically-Tuned Applied Kinetics) system delivers an unmistakable, race-inspired exhaust note while utilizing Borla's patented straight-through muffler technology to eliminate the drone commonly associated with aggressive aftermarket exhausts.
Constructed from premium T-304 austenitic stainless steel, the system features mandrel-bent 2.75-inch tubing for maximum exhaust flow and quad 4.25-inch polished stainless steel tips that perfectly fill the factory rear valance. The result is improved exhaust tone, enhanced throttle response, and the legendary Borla Sound of Power backed by the company's renowned Million-Mile Warranty. If you're looking for maximum volume and an aggressive muscle car sound without sacrificing highway comfort, the ATAK is the ultimate axle-back upgrade.

Why Upgrade?
If your C7 Stingray is equipped with the standard exhaust system, the Borla ATAK is one of the most dramatic upgrades you can make. It transforms the factory-muted LT1 into an aggressive, high-performance V8 while maintaining Borla's signature drone-free cruising characteristics. For even greater performance and sound, pair the ATAK axle-back with the Borla 60548 X-Pipe to create a full cat-back system with increased exhaust flow and an even more exhilarating exhaust note.
