LT Ceramic Coated Long Tube Headers for 1968-1972 Chevelle, GTO, Cutlass, Skylark
When installing an LT engine into a 1968 to 1972 A body Chevelle, GTO, Cutlass, or Skylark, these LT Ceramic Coated Long Tube Headers address the need for direct exhaust flow and precise port alignment. Each tube is crafted from premium mild steel and finished with a multi layer ceramic coating to retain heat within the stream, while the precision CNC formed flanges are machined to a 3/8 inch thickness to match factory exhaust ports exactly. Mandrel bending preserves a smooth internal profile through all 1 7/8 inch tubes for improved exhaust scavenging and reduced turbulence. Supplied hardware includes V band clamps, composite gaskets, and high grade bolts for a secure, leak resistant seal on any A body chassis with an LT series engine.
Design and Fitment
These LT Ceramic Coated Long Tube Headers are engineered specifically for 1968 to 1972 A body LT series engine installations. Each tube measures 1 7/8 inch in diameter to optimize exhaust scavenging and pulse tuning for this family of engines. Integration with factory A body mounts ensures correct engine placement and maintains precise drivetrain angles, preserving alignment and reducing stress on powertrain components. This tailored fitment eliminates guesswork during installation and delivers a seamless marriage of engine and chassis.
Manufacturing Quality
Precision is built into every component of these headers. The flanges are formed on CNC equipment to a thickness of 3/8 inch, providing a surface that mates perfectly with cylinder head ports and resists warping under repeated heat cycles. Premium mild steel tubing is selected for its ability to withstand high temperature and internal pressure without cracking or deforming over time. Smooth bead joints are MIG welded using expert technique, resulting in consistent weld profiles that resist fatigue and maintain structural integrity after thousands of heat up and cool down sequences.
Thermal Management and Flow
A proprietary multi layer ceramic coating is applied to the exterior of each tube and merge collector to reduce underhood temperature and protect surrounding components. By forming an insulating barrier the coating keeps critical sensors and fuel lines at safer operating temperatures. It also promotes exhaust gas velocity, improving scavenging at low and midrange engine speeds. Drivers will notice crisper throttle response and a broader torque curve as hot gases exit smoothly and quickly from the cylinders.
With precise CNC formed flanges, premium mild steel construction, and ceramic coated tubes, these headers ensure leak-resistant installation and consistent exhaust flow for your LT swap.
