1-7/8 Ceramic Coated Long Tube LT Headers for 1971-1976 B-Body Impala Caprice
Swapping an LT motor into your 1971 through 1976 Impala or Caprice B-Body demands headers that match the factory port layout while streamlining exhaust flow from the cylinder heads. These 1 7/8 inch ceramic coated long tubes feature a durable layered ceramic finish that keeps heat within the exhaust path and reduces underhood temperatures in tight engine bays. Each header is built with precision CNC formed 3/8 inch flanges that seal against factory ports to eliminate leaks and simplify LT engine installation with gaskets, bolts, and V-band clamps provided.
Multi-Layer Ceramic Finish for Heat Retention and Protection
The 1 7/8 inch tubes are coated in multiple layers of ceramic that reflect radiant heat back into the exhaust stream, improving scavenging and boosting cylinder efficiency. By trapping thermal energy within the tubes rather than letting it radiate underhood, the headers reduce ambient bay temperatures and protect vulnerable wiring and hoses from heat damage. The layered finish also forms a rigid shell that resists abrasion and thermal cycling over repeated use. Enthusiasts benefit from more consistent performance and a cooler engine bay environment.
Precision CNC Flanges for Factory Port Fit
Each flange is CNC formed to 3/8 inch thickness and machine cut to exactly match the LT port pattern on 1971 through 76 Impala and Caprice B Body heads. This precision ensures uniform contact with the cylinder head face, eliminating warping and gasket blowouts even under high torque. Paired with composite gaskets and secure V band clamps, the design delivers a leak free seal that holds through vibration and thermal expansion. Installers appreciate fewer retorquing cycles and reliable exhaust integrity.
Mild Steel Tubing and MIG Welds Built for Durability
Constructed from premium mild steel, the tubes offer an ideal balance of strength and formability for smooth flow while resisting deformation at high temperatures. The smooth MIG welds create uniform joints that resist fatigue and cracking over continuous thermal cycles. Mandrel bends preserve consistent diameter through each curve, reducing flow disruptions and back pressure. These choices combine to deliver a header set that endures the demands of both street cruising and track use.
Complete Hardware Pack for Simplified LT Swap
This header set comes with all required composite gaskets, high grade bolts and V band clamps in one package to streamline installation and remove guesswork. By providing properly sized hardware from the start, the kit ensures correct torque application and reduces the risk of leaks or damage from mismatched parts. The inclusive approach cuts installation time and maintains clean engine bay packaging for a factory style appearance. Whether in a home garage or professional shop, installers gain confidence from a ready to use solution.
Engineered for precise fitment and reliable performance in your LT swap project.
