Ceramic Coated LT Long Tube Headers for 1971-1976 B-Body Impala/Caprice
Swapping an LT engine into a 1971 to 1976 B Body Impala or Caprice demands headers engineered for precise exhaust routing and thermal management from the moment installation begins. These 1 7/8 inch diameter tubes use CNC machined flanges cut to the LT port pattern, delivering a secure and leak resistant seal against each cylinder head. By reflecting radiant energy back into the exhaust flow, the layered ceramic coating traps heat inside the tubes, lowers underhood temperatures and protects surrounding hoses and wiring from premature wear. Complete with gaskets, mounting bolts and V band clamps, this set arrives ready to install and cuts swap time by providing every necessary component while maintaining a clean engine bay.
Advanced Ceramic Layering for Enhanced Thermal Management
The multi layer ceramic coating applied to each mild steel tube plays a crucial role in controlling underhood heat. By reflecting radiant energy back into the exhaust stream, this finish helps maintain higher gas velocity and improves scavenging efficiency as exhaust pulses exit the cylinder head. Reduced heat soak protects nearby hoses, wiring and intake components from premature aging and minimizes cabin temperature rise during extended highway runs. Over repeated heating cycles, the rigid ceramic shell resists cracking or peeling, ensuring consistent thermal performance and long term protection for critical engine bay elements.
Precision CNC Formed Flanges for Leak Resistant Sealing
CNC machining delivers flanges cut to the exact LT port pattern on 1971 to 1976 B Body Impala and Caprice heads, with a uniform thickness of 3/8 inch to prevent warpage. This level of precision guarantees full face contact between header flange and cylinder head, creating a reliable seal that minimizes exhaust leaks even under heavy load and constant vibration. When paired with the provided composite gaskets and V band clamps, installers achieve a joint that requires fewer retorque checks and delivers a stable exhaust path under all driving conditions. The result is a cleaner installation that maintains consistent backpressure for peak performance.
Mandrel Bent Tubing and MIG Weld Construction for Durability
Each long tube is crafted from domestically sourced mild steel and shaped using smooth mandrel bends that preserve a constant internal diameter, eliminating restrictions commonly found in stamped or crush bent designs. High quality MIG welds join the primary tubes to the flanges with uniform penetration, creating fatigue resistant seams capable of withstanding repeated expansion and contraction from high heat cycles. This robust construction not only prolongs the life of the headers but also maintains optimal exhaust flow over years of street and track use. The combination of material choice and fabrication technique ensures these headers deliver reliable performance under demanding operating conditions.
Comprehensive Hardware Kit Simplifying the LT Engine Swap
This complete header package arrives with composite gaskets, high grade bolts and V band clamps sized to the precise flange interface, eliminating the need for aftermarket fastener searches. By including every mounting component in one box, the kit reduces installation time and lowers the risk of mismatched parts or incorrect torque values. Installers benefit from a streamlined process that keeps the engine bay organized and tidy, allowing them to focus on wiring and accessory integration rather than scavenging hardware. With everything on hand, the swap to an LT engine in your 1971 through 1976 B Body becomes a straightforward and repeatable procedure.
Engineered for a precise fit and dependable thermal management during your LT swap.
