1-7/8 Inch Ceramic LT Headers for 1973-1977 A-Body Swaps

Optimized 1-7/8 inch primaries and a layered ceramic coating enable lower underhood temperatures while unlocking stronger horsepower and torque for your 1973-1977 A-Body LT swap. CNC formed 3/8 inch flanges and premium mild steel tubing with MIG welded joints ensure a leak resistant seal under vibration while the tubular layout enhances exhaust scavenging for crisp throttle response and lasting durability.

1973-1977 A-Body LT Ceramic Coated Long Tube Headers for Buick Chevrolet Oldsmobile Pontiac

When fitting an LT engine into a 1973-1977 A-Body chassis, tight clearance and thermal management around the exhaust ports demand a precise header solution. The 1973-1977 A-Body 1-7/8 LT Ceramic Coated Long Tube Headers offer CNC formed 3/8 inch flanges that match factory ports and a durable multi layer ceramic coating to reflect radiant heat back through the primaries. Included V band clamps with composite gaskets secure a leak resistant joint that stands up to constant vibration and heat cycling. Beyond protecting wiring and hoses under the hood, this design promotes stronger torque response by optimizing exhaust scavenging through smooth 1 7/8 inch tubes.

Precision Engineered Flanges for Reliable Exhaust Seal

The flanges on these headers are CNC formed to millimeter accuracy, matching factory LT engine ports without gaps or uneven surfaces. This precision mating surface, when paired with included V band clamps and composite gaskets, creates a leak resistant joint that holds firm under constant vibration and heat expansion. Installers experience fewer retorque cycles and maintain consistent exhaust backpressure for smooth throttle response. By eliminating exhaust leaks, this design also reduces noise and helps preserve tune stability throughout every mile.

Advanced Ceramic Coating for Efficient Thermal Management

A multilayer ceramic finish bonds tightly to mild steel tubing and forms a hard shell that reflects radiant heat back into the exhaust stream. This retained heat increases gas velocity inside each primary, improving scavenging while sharply reducing underhood temperatures. Lower ambient heat levels protect nearby wiring, fuel lines and sensors from premature aging. The coating resists abrasion and repeated heating without flaking, ensuring lasting performance and consistent thermal control in demanding LT engine swap applications.

Tubular Primary Design for Enhanced Scavenging and Torque Response

Each primary tube features a smooth one and seven eighths inch bore and carefully engineered bends that promote uninterrupted exhaust flow. By minimizing sharp turns and diameter changes, the design sustains high gas velocity and creates a scavenging effect that draws fresh intake charge more efficiently. Drivers feel stronger low end torque and crisper midrange power delivery as backpressure remains balanced. This consistent flow behavior across the rpm band contributes directly to improved throttle response and overall engine efficiency.

Robust Mild Steel Construction for Thermal Stress Resistance

Built from premium mild steel, these headers combine strength and ductility for crack resistant durability under constant heating and cooling cycles. High integrity MIG welded joints deliver uniform weld beads that resist fatigue and maintain structural integrity over thousands of miles. The material tolerates thermal expansion without developing stress fractures, making it ideal for both street driving and track use. By focusing on durable steel and reliable weld quality, the headers provide long service life and dependable performance in every LT swap.

Engineered for a precise fit and reliable performance in your LT swap project, these headers ensure consistent exhaust flow and thermal control.
