2" x 3" 304-stainless long-tube headers plus catalytic-converter-equipped connection pipes (EPA-compliant high-flow cats), all mounting hardware included. Kooks recommends pairing with O2 sensor spacers (PN 9003A) to avoid check-engine codes.
why this one — Same Kooks long-tube header quality as HDR-KOOKS-13722400-RAPR, but bundled with catted connection pipes so it is a complete bolt-in, street-legal system rather than requiring separately-sourced connection pipes. Confirmed live on kooksheaders.com 2026-07-23.
