LS 1-7/8 Ceramic Coated Mid-Length Headers for G-Body
Swapping an LS powerplant into a 1978 to 1988 G-Body chassis demands headers that blend precise fitment with temperature control. These one and seven eighths inch ceramic coated mid length headers clear frame rails and steering linkages while optimizing exhaust flow for sharper throttle response. Each flange is machined from thick steel plate to maintain a leak free seal against LS cylinder heads under varying loads. Installation goes smoothly on both manual gearboxes and popular automatics such as the 4L60E and 4L80E so builders can focus on tuning rather than adapters.
Engine Bay Heat Management with Ceramic Coating
The silver ceramic finish on these headers forms a durable thermal barrier that cuts radiant heat transfer in the engine bay. By reflecting intense heat away from wiring harnesses and coolant lines, it helps prolong the life of sensitive components. This barrier also resists flaking and oxidation through repeated heat cycles, ensuring that the steel tubing maintains its structural integrity. The net effect is more consistent underhood temperatures, which supports stable engine tuning and prevents heat soak during spirited driving.
Exhaust Scavenging Optimized by Tube Diameter
One and seven eighths inch primaries are sized to enhance exhaust pulse tuning and promote efficient gas evacuation. This specific diameter accelerates the flow of spent exhaust, creating a scavenging effect that draws fresh air fuel mixture into each cylinder more quickly. Drivers will notice sharper throttle response and a wider power band as low speed torque benefits from improved exhaust flow. This balance of torque and horsepower makes the swap suitable for daily driving as well as performance applications.
Steel Flange Engineering for Durable Sealing
Each flange is machined from three eighths inch steel plate to provide a rigid mounting surface that resists warping under heavy heat and pressure. This thickness ensures that the gasket surface remains flat, preventing exhaust leaks that can reduce engine efficiency. Critical joints are TIG welded for precise fusion between flange and tubing, reinforcing the header structure at its most vulnerable points. Consistency in flange flatness and weld quality translates into long term sealing reliability across countless heat cycles.
Smoother Installation with 4L60E and 4L80E Transmissions
Designed specifically for 1978 through 1988 G-Body chassis, these headers slide into place without interfering with frame rails or steering linkages. Compatibility with popular automatic transmissions such as the 4L60E and 4L80E means builders can bolt in complete exhaust hardware without adapter kits or modifications. Included gaskets and hardware streamline the assembly process, allowing focus on tuning rather than fabrication. The result is a plug in solution that speeds up LS engine swaps and maintains factory mounting points.
