Product Description

The Stainless Works C72CAT is a complete long tube header and catted X-pipe system for the 2014-2019 Chevrolet Corvette C7 Stingray and Grand Sport with the LT1 6.2L V8. Featuring 2" CNC mandrel-bent 304 stainless steel primaries at 31" length feeding into 3" slip-fit collectors, this system maximizes exhaust flow for significant horsepower and torque gains over the factory manifolds.

The included 3" X-pipe center section with high-flow catalytic converters connects directly to the factory axle-back, allowing you to retain your existing rear muffler section. The headers include easy access wideband O2 ports for aftermarket wideband sensor installation, and the X-pipe features additional O2 bungs for tuning. O2 sensor extension harnesses are included for proper routing. Not CARB legal. ECU tune required. Covered by Stainless Works' lifetime warranty.
