1968-1972 A-Body LS Ceramic Coated Mid-Length Headers
Swapping an LS powerplant into a 1968-1972 A-Body sedan or coupe often runs into tight frame rail clearance and fitment issues that demand a tailored exhaust solution. These 1968-1972 A-Body LS 1 7/8 Ceramic Coated Mid-Length Headers precisely match LS ports and guide exhaust gasses efficiently away from the engine bay. Built from three eighths inch thick steel and finished with a high temperature ceramic coat they reflect heat back into the system to lower underhood temperatures and resist corrosion over time. Installation is straightforward with factory style flanges and included gaskets to ensure a leak free seal so throttle response and torque delivery remain consistent through the rev range.
Precision Steel Flange Ensures Leak Free Sealing
Built with a thick three eighths inch steel flange, these headers maintain an unbroken seal against the LS cylinder head for reliable exhaust containment. The robust flange resists distortion under repeated heat cycles, so gaskets remain crushed just enough to block escape paths for exhaust gases. By preserving contact between the port and header surface, the design sustains stable torque delivery and prevents the power loss that can occur when hot gases leak. This solid steel construction also stands up to vibration and thermal stress in classic A Body frames. As a result, these headers deliver consistent performance mile after mile without the need for constant retightening.
Ceramic Coating Delivers Underhood Heat Control
A durable silver ceramic coating covers each primary tube and flange to reflect radiant heat back into the exhaust stream and accelerate gas flow. This thermal barrier dramatically reduces underhood temperatures, safeguarding wiring, hoses, and other components from heat soak. The coating also forms a corrosion resistant layer that resists pitting and rust when exposed to moisture and road debris. Over time, this finish preserves both appearance and structural integrity, so the headers continue to perform and look good season after season. The result is a cooler engine bay that supports accessory longevity and easier tuning.
1 7/8 Inch Primary Tubes for Improved Scavenging
Each primary tube measures a carefully chosen 1 7/8 inches in diameter to strike the right balance between exhaust velocity and volume across the rpm range. At low engine speeds, the diameter promotes efficient scavenging, improving cylinder evacuation for crisper throttle response around town. As rpm climbs, the primaries avoid excessive backpressure that can sap top end power, allowing the LS engine to breathe freely. This calibration ensures a broad and usable torque curve ideal for daily driving, spirited cruising, or light towing. Drivers enjoy a more responsive feel under acceleration without sacrificing highway performance.
Custom Fit for 1968 to 1972 A Body Frame Clearance
Specifically engineered for 1968 to 1972 A Body sedans and coupes, these mid length headers clear tight frame rails and guide exhaust gases cleanly away from the engine bay. Precise alignment with LS port locations means factory style flanges and included gaskets drop in without modification or guesswork. Installers benefit from plug and play fitment that avoids contact with steering components or suspension brackets. This tailored approach reduces installation time and eliminates the need for custom heat shields. Owners gain both hassle free assembly and a system that works seamlessly with existing undercarriage geometry.
Engineered for precise fit and consistent performance in your 1968 to 1972 A Body LS swap.
