Exhaust Header Set Mopar Gen III Hemi Dodge Truck

The HOOKER Exhaust Header Set for Mopar Gen III Hemi Dodge trucks is a stainless steel performance upgrade designed to maximize exhaust scavenging and engine efficiency on 2WD Ram full-size trucks. With 1.875-inch primary tubes flowing into a 3-inch collector, this header set replaces restrictive factory manifolds and unlocks measurable gains in horsepower and torque across the RPM band.

The 1.875-inch primary diameter is engineered for Gen III Hemi displacement and airflow characteristics, optimizing scavenging without over-sizing tube diameter—which would kill low-end velocity. The 3-inch collector consolidates exhaust flow smoothly into your existing exhaust system, reducing backpressure and thermal stress on the engine bay. Stainless steel construction resists corrosion from combustion byproducts and moisture, critical for trucks operating in varied climates or near saltwater environments. The pair includes all necessary mounting hardware, and the natural finish allows direct powder coating or ceramic coating if desired.

This header set is engineered for serious enthusiasts building or upgrading Gen III Hemi power. Whether you're tuning a street truck for improved throttle response and fuel economy, or preparing a Ram for higher-output applications, proper exhaust scavenging is foundational. The HOOKER headers work with most aftermarket exhaust systems and are compatible with 2WD chassis geometry without additional fabrication. Installation requires standard hand tools and basic mechanical knowledge.

Gen III Hemi trucks benefit from headers more than factory vehicles because the engine platform responds well to improved exhaust flow—gains are additive when combined with intake and tuning modifications. The stainless construction and complete hardware package justify the investment compared to raw cast-iron alternatives that require regular maintenance and offer limited durability in high-heat or corrosive environments.
