Product Description

The Kooks 21606750 is a 3 in. shotgun-style valved axle-back exhaust engineered specifically for the 2006-2013 Chevrolet Corvette C6 Z06 and ZR1. The vacuum-operated valve system gives drivers on-the-fly control over exhaust tone - from a refined rumble in the closed position to a thunderous, open-exhaust roar when fully opened. Built from T304 stainless steel with carbon fiber tips, this system delivers both performance gains and a premium visual upgrade over the stock exhaust.

Installation is straightforward - the system connects directly to the OEM mid-section or drops in behind Kooks headers and an X-pipe for a full-system build. Note that vacuum line extensions for the valves are not included and may be needed depending on routing. Handcrafted in Statesville, NC and built to order, the 21606750 is the ideal finishing piece for any C6 Z06 or ZR1 performance build.
