82-87 S10 V6 4wd

The Hedman 82-87 S10 V6 4wd headers (Model 69370) are purpose-built performance exhaust manifolds designed for first-generation Chevrolet S-10 trucks equipped with V6 engines and four-wheel-drive configurations. These headers represent a critical upgrade for mechanics and enthusiasts who recognize that factory cast-iron manifolds restrict exhaust scavenging, reduce horsepower, and generate excessive underhood heat. By replacing restrictive OEM components with tuned tube geometry, the 82-87 S10 V6 4wd headers unlock measurable gains in both power delivery and engine efficiency while improving thermal management in the engine bay.

Manufactured by Hedman—a trusted name in aftermarket exhaust engineering—these headers feature mandrel-bent primary tubes sized to match the V6's optimal scavenging frequency, promoting cylinder evacuation and low-end torque response. The multi-tube design reduces backpressure while maintaining ideal exhaust velocity, critical factors in a naturally aspirated V6 platform. Constructed from heavy-gauge steel with a durable finish, the headers are engineered to withstand the rigors of both street and off-road duty without warping or cracking. Precise fitment is ensured for the 1982–1987 model year S-10 V6 4wd platform, accounting for engine bay clearances specific to four-wheel-drive frame geometry, suspension components, and steering linkage.

This upgrade is ideal for S-10 V6 4wd owners pursuing comprehensive powertrain modifications, from mild street builds to serious off-road performers seeking improved throttle response and reduced heat soak during towing or trail work. Installation pairs seamlessly with a quality cat-back exhaust system to maximize gains; standalone header installation alone provides noticeable improvement in mid-range power and engine longevity by lowering peak temperatures. Weighing 25.3 lbs and dimensioned at 16.5 x 8.5 x 39.1 inches, the headers fit within the tight confines of first-gen S-10 engine bays without interference with air conditioning, power steering, or four-wheel-drive transfer case components. Professional installation is recommended to ensure proper gasket sealing and correct collector alignment.
