Ceramic Coated 1-7/8 Long Tube Headers for LT Engine Swaps in 1970-1981 F-Body Camaro Firebird
Swapping an LT powerplant into a 1970 to 1981 Camaro or Firebird chassis often exposes weak exhaust flow and excess underhood heat; these F Body 1 7/8 LT Ceramic Coated Long Tube Headers address both challenges with targeted design. By reflecting radiant energy back into the exhaust stream the ceramic barrier keeps tube walls hot and lowers surrounding temperatures while sharpening scavenging pulses across the rpm range. With precision mandrel bent 304 stainless steel tubes and CNC formed flanges including gaskets and sensor bungs this assembly delivers reliable fit and leak free joints under repeated heat cycles.
Advanced Ceramic Coating for Efficient Heat Control
The multi layer ceramic barrier applied to each 1 7/8 inch primary tube acts as a thermal insulator that reflects radiant energy back into the exhaust stream. By keeping tube walls hotter, it sustains faster gas velocities that sharpen scavenging pulses throughout the rpm band. Beneath the finish, adjacent wiring looms, intake tracts, and sensors remain protected from excessive underhood heat, reducing the chance of heat soak and component fatigue. Unlike conventional paint options that crack or flake under high temperatures, this ceramic layer resists abrasion and chemical attack from road debris and moisture. Technicians will note that the consistent surface integrity maintains thermal performance even after repeated heat cycles, contributing to both power gains and longer service life.
Mandrel Bent 304 Stainless Steel for Uninterrupted Gas Flow
Each primary runner is formed from 304 stainless steel tubing using a mandrel bending process that preserves a uniform 1 7/8 inch diameter through every curve. This approach prevents the inner wall from collapsing or creating flow restrictions, resulting in minimal turbulence and back pressure. The inherent corrosion resistance of 304 steel ensures that humidity, salt spray, and repeated temperature changes will not compromise the header's strength or appearance. Because there are no weld seams in critical flow zones, stress cracks are far less likely to develop during extended hot and cold cycles. Enthusiasts benefit from reliable, consistent performance as exhaust gases exit freely and maintain steady scavenging that supports strong torque delivery at low and midrange engine speeds.
Precision CNC Flanges for Exact Port Alignment and Reliable Seals
The 3/8 inch thick stainless flanges are CNC machined to mirror the factory exhaust port geometry on first generation F-Body LT installations. Accurate port matching eliminates gaps that might otherwise lead to exhaust leaks or noise and preserves the scavenging effect critical to improved performance. When used with the supplied composite gaskets and high grade bolts, these flanges maintain a tight seal through repeated thermal expansion and chassis vibration. The uniform flange thickness and true bolt pattern keep torque application even, reducing installer guesswork and minimizing the need for follow-up retorques. This level of precision not only speeds up the swap process but also ensures long term sealing integrity under demanding driving conditions.
Engineered for precise fit and consistent exhaust flow this header ensures reliable sealing even under repeated heat cycles.
