Hawks Motorsports is pleased to offer our clients the following 1982-1992 Camaro/Firebird LSX Conversion 1-7/8" x 3" Stainless Steel Mid-Length Headers by Kooks, part number 22311400.

An LS swap in a third-gen deserves an exhaust setup built around the swap instead of a collection of parts that almost fit. These Kooks mid-length headers give your 1982-1992 F-body 1-7/8-inch primaries feeding into 3-inch collectors, providing a serious foundation for getting the exhaust out of a round-port LS combination. When you're stuffing modern LS power into a classic third-gen engine bay, having headers designed specifically for the conversion makes the build a whole lot cleaner.

Kooks part number 22311400 is built from 304 stainless steel and is designed specifically for 1982-1992 Chevrolet Camaro and Pontiac Firebird LSX engine swaps using round-port LS-style cylinder heads, including LS1, LS2, LS3, and LS6-style applications. These mid-length headers feature 1.875-inch primary tubes and require the specified Spohn 4th Gen adapter motor mount configuration for installation. The current Kooks part number replaces older part number 292140.
