72-93 SBM Truck Headers

The 72-93 SBM Truck Headers by FLOWTECH are specifically designed for small-block Chevrolet engines in full-size trucks from the 1972 to 1993 model years. These headers are ideal for builders looking to enhance performance by replacing restrictive factory cast-iron manifolds that limit exhaust flow and reduce horsepower.

Featuring a tuned four-into-one design, these headers improve exhaust gas evacuation by minimizing back-pressure and enhancing scavenging. The stepped primary tubes are engineered to optimize flow characteristics across various RPM ranges, reducing turbulence and maximizing energy efficiency. Weighing 37 lbs, these headers provide robust construction while ensuring that engines can breathe freely.

Mechanics and enthusiasts appreciate the FLOWTECH headers for their compatibility with standard engine bay dimensions, making them suitable for both stock and modified exhaust systems. While installation typically requires basic hand tools and some mechanical skill, it is advisable to mock-up the headers before final tightening to ensure a proper fit.
