LS Swap Exhaust Headers Fit for Chevy S10 Blazer GMC Sonoma Jimmy 1982-2005 2WD

Performance exhaust headers designed for compatible Chevrolet S10, GMC Sonoma, Chevrolet S10 Blazer, GMC Jimmy, and Oldsmobile Bravada applications undergoing an LS-series V8 engine swap. Featuring 1-5/8 in primary tubes, 2-1/2 in collectors, 3/8 in thick head flanges, and supplied exhaust starter tubes with O2 sensor bungs, this header set is designed around the tight chassis clearance found in these older truck and SUV platforms. These headers are intended for LS-series engine swaps only and are not compatible with standard SBC or BBC engines or 4WD applications.
