Product Description

The Borla 11816 ATAK Axle-Back Exhaust System is engineered specifically for 2005-2008 Chevrolet Corvette C6 models equipped with the 6.0L or 6.2L V8 engine. This performance exhaust delivers one of the most aggressive and track-inspired sound profiles in Borla's lineup thanks to ATAK (Acoustically-Tuned Applied Kinetics) technology, which calibrates internal muffler cores for maximum exterior sound without harsh cabin resonance. Constructed from premium T-304 stainless steel with mandrel-bent tubing and a straight-through muffler design, this system enhances exhaust flow to improve throttle response and overall performance while resisting corrosion for long-term durability.

Installation is straightforward with a direct bolt-on design that uses factory mounting points, making it suitable for both experienced DIY enthusiasts and professional installers. The dual split rear exit with polished stainless steel tips not only improves exhaust efficiency but also gives the rear of your Corvette a bold motorsport appearance. This Borla system fits Corvettes with or without NPP (active exhaust valves), although the system itself does not include NPP valves. Backed by Borla's Million-Mile Warranty, the 11816 ATAK Axle-Back Exhaust is ideal for drivers seeking uncompromising sound, improved flow, and enhanced performance over the stock exhaust.
