Product Description

The Kooks 2160H432 is a complete long tube header and catted X-pipe kit engineered specifically for the 2009-2013 Chevrolet Corvette C6 equipped with the LS3 6.2L V8. The 1-7/8 in. primary tubes feed into 3 in. collectors, improving exhaust scavenging and reducing backpressure compared to factory manifolds. The bundled Kooks GREEN high-flow catalysts are EPA-verified and rated to handle up to 750 RWHP, making this system capable of supporting both naturally aspirated and moderately boosted LS3 builds.

Installation is bolt-on using the included gaskets, hardware, and O2 extension harnesses, connecting to the stock 2-1/2 in. OEM-style exhaust. Torca swivel-seal connections ensure a leak-free, rattle-free fit. An ECU tune is strongly recommended after installation to maximize gains and maintain proper air-fuel calibration. Handcrafted in Statesville, NC and backed by a limited lifetime warranty, the 2160H432 is one of the most complete header solutions available for the C6 LS3 platform.
