Borla ATAK Axle-Back Exhaust - Ceramic Black (11903CB) - 2015-2019 C7 Corvette Z06 & Grand Sport
The Borla ATAK Axle-Back Exhaust with Ceramic Black tips for the 2015-2019 C7 Corvette Z06 and 2017-2019 Grand Sport (manual transmission only) delivers the most aggressive, high-intensity sound available while retaining full NPP valve functionality. This system does NOT include AFM valves, making it ideal for high-performance Corvette models that do not use AFM. Designed for Z06 models (automatic or manual) and Grand Sport models with manual transmission, this system provides maximum volume with zero harsh cabin resonance.
ATAK (Acoustically-Tuned Applied Kinetics) technology uses vehicle-specific muffler core tuning to maximize volume, clarity, and character without introducing drone. The 2.75" piping produces a razor-sharp exhaust note that perfectly complements the LT4 and LT1 powerplants. Each muffler features dual 4.25" round intercooled T-304 stainless steel tips finished in a durable high-temperature Ceramic Black coating for a stealthy, motorsport-inspired appearance. A polished tip version is also available.
Constructed from premium T-304 austenitic stainless steel, this system offers superior durability and corrosion resistance compared to lower-grade materials. Ultra-smooth mandrel bends maximize flow and performance, while precision CNC manufacturing ensures a perfect fit on all compatible Z06 and Grand Sport models. Borla backs the system with a Million-Mile Warranty on non-moving components, with valves warrantied for one year.
