Product Description

The Borla 11863 ATAK Axle-Back Exhaust System is engineered specifically for 2014-2019 Chevrolet Corvette C7 models equipped with the 6.2L V8 engine and rear-wheel drive, designed to deliver a bold and commanding exhaust tone. Utilizing Borla's ATAK (Acoustically-Tuned Applied Kinetics) technology, this exhaust produces one of the most aggressive sound profiles in the Borla lineup while maintaining quality and durability. Constructed from high-grade T-304 stainless steel with mandrel-bent tubing and a straight-through muffler design, the system enhances exhaust flow to improve throttle response and overall performance compared to the stock system.

The quad center rear exit with polished intercooled stainless steel tips not only improves rear styling but also contributes to improved exhaust velocity and performance. Installation is a direct bolt-on process using factory mounting points, and the system includes all necessary hardware for a professional-grade fitment. Specifically targeted for C7 Corvettes equipped with AFM valves and without NPP valves, this system is **not compatible** with Grand Sport models fitted with manual transmissions. Backed by Borla's Million-Mile Warranty, the 11863 ATAK Axle-Back Exhaust is ideal for enthusiasts who want enhanced sound, improved exhaust flow, and a performance-oriented upgrade over the factory exhaust.
