1968-1972 A-Body LS Ceramic Coated Mid-Length Exhaust Headers
If you're fitting an LS powerplant into a 1968 to 1972 GM intermediate chassis these mid length ceramic coated headers deliver the precise mounting alignment needed for a clean installation. Each primary tube measures 1 7/8 inch to balance gas velocity and backpressure across the rpm range and improves throttle response in low and midrange rpm. Constructed from heavy gauge steel with thick flanges the silver ceramic finish reflects radiant heat back into the exhaust stream and protects critical components such as wiring and intake manifolds under the hood. With factory bolt patterns on models from Skylark to Cutlass these headers simplify installation and maintain a leak proof seal for consistent performance and durability.
Optimized Scavenging with 1 7/8 Inch Mid Length Tubes
The 1 7/8 inch primary tubes are sized to strike an ideal balance between exhaust velocity and backpressure, enhancing scavenging at low and midrange engine speeds. By using a mid length layout, this design minimizes turbulence compared to full length systems, resulting in more consistent gas flow and stronger torque delivery. Precision mandrel bends preserve tube diameter through each curve, preventing pinch points that could slow exhaust pulses. The result is improved throttle response and a noticeable uptick in drivability during everyday use. Engine dyno tests confirm that this configuration yields a smooth power curve without sacrificing low rpm punch. Overall, these headers translate raw LS potential into usable street performance.
Ceramic Coated Finish for Engine Bay Heat Control
The silver ceramic coating acts as a radiant barrier that reflects heat back into the exhaust stream, keeping temperatures under the hood in check. By containing thermal energy inside the tubes, critical elements such as wiring, hoses and intake manifolds run cooler and maintain reliability over long drives. This thermal management also preserves exhaust gas energy, helping maintain smooth pulse flow and reducing underhood heat soak during spirited driving or highway cruising. The coating resists abrasion and withstands repeated heating cycles without flaking or chipping. As a result, you get consistent performance plus easier maintenance of neighboring components. Heat control is essential for high output LS applications in vintage chassis.
Heavy Gauge Steel Structure with Thick Flanges
Constructed from robust steel, these headers endure extreme temperature swings without metal fatigue or distortion. Each flange is machined to a substantial 3/8 inch thickness, providing a flat, stable mounting surface for a leak proof seal. Precise welding at each joint reinforces structural integrity and prevents cracks under road vibration or track use. The combination of heavy gauge material and rigid flanges ensures that gasket seating remains consistent over many heat cycles. This build quality translates to reliable exhaust containment and sustained engine efficiency. You benefit from a durable assembly that resists warping and maintains performance mile after mile.
Tailored Fit for 1968 to 1972 GM A Body Platforms
These headers are engineered to match the original bolt pattern on GM intermediate chassis from 1968 to 1972, including Skylark, Cutlass and other A body models. By aligning precisely with factory mount points, the design eliminates the need for trimming or modification, streamlining installation for street rods and restorations. Perfect alignment reduces stress on fasteners and gaskets, helping prevent exhaust leaks that can rob power or damage components. The straightforward fit allows builders to retain OE frame geometry and steering clearance without interference. Installation becomes a matter of unbolt and secure, keeping swap projects on schedule. This exacting fit makes these headers an ideal choice for LS swaps in classic GM machines.
Built for a seamless fit and dependable operation, this header set delivers consistent LS performance mile after mile.
