LT Ceramic Coated Mid-Length Headers for 1968-1972 A-Body Chevelle/GTO/Cutlass/Skylark
When you bolt an LT small block into a 1968 to 1972 A-body Chevelle, GTO, Cutlass or Skylark these ceramic coated mid-length headers ensure exhaust flow is routed cleanly while matching factory port spacing to prevent leaks and misalignments. Precision CNC formed tubes and machined flanges provide a snug fit that holds steady under vibration without extra shims or torque. The dense ceramic finish reflects heat back into the exhaust stream to sustain hotter gas temperatures and enhance scavenging across the rpm band. Under repeated thermal cycles the mild steel construction and tight weld beads resist fatigue for reliable performance on street and track alike.
Multi Layer Ceramic Coating for Enhanced Heat Management
The multi layer ceramic finish on these 1 7/8 inch long tubes creates a dense thermal barrier that reflects heat back into the exhaust stream. By maintaining hotter gas temperatures, scavenging is improved across the engine rpm range which helps sustain torque and overall power output. At the same time, the coating keeps underhood temperatures lower to protect wiring, hoses and other sensitive components from heat soak. Over repeated thermal cycles the ceramic layers resist chipping and abrasion, ensuring consistent performance without fading or peeling. This controlled heat retention also aids exhaust velocity for a more responsive throttle feel.
Precision CNC Machined Flanges for Leak Free Sealing
Each flange is CNC formed and milled to a precise 3/8 inch thickness to match factory port dimensions exactly. This level of accuracy eliminates misalignment and prevents exhaust leaks under both vibration and thermal expansion. When installed with the composite gaskets and V band clamps provided, the headers achieve a secure seal without the need for shims or excessive torque. The consistency of these machined flanges ensures repeatable fitment during routine maintenance or engine swaps. As a result, the joint integrity remains intact through street driving and demanding track environments.
Robust Mild Steel Tubing and MIG Welded Joint Strength
Constructed from premium mild steel, the tubing offers an ideal balance of strength and malleability for complex bends within the tight engine bay of a B body installation. Mandrel bending preserves a consistent internal diameter, reducing turbulence and promoting smooth exhaust flow. Precision MIG welded beads join each section with uniform weld profiles that resist fatigue through countless heat up and cool down cycles. This combination of material and welding technique delivers a header assembly capable of withstanding high exhaust pressure and extreme temperature swings. The overall design ensures lasting durability and reliable performance on both street and race applications.
These headers offer reliable leak free sealing and robust durability for your LT engine swap project.
