LS 1-7/8 Inch Ceramic Coated Mid-Length Headers for X-Body Models
When fitting an LS series engine into a 1968 to 1974 GM X Body chassis, precise tube routing and flange alignment ensure reliable exhaust flow and adequate clearance. These 1 7/8 inch ceramic coated mid length headers are made of steel and custom engineered for integration with MuscleRods engine mount kits. Three eighth inch thick flanges mirror LS port spacing for a leak proof seal, and the silver ceramic finish resists heat and corrosion. Tubes clear frame rails to preserve ground clearance, and included gaskets and bolts make installation straightforward. Optimized exhaust flow across the rev band supports a balanced torque curve for spirited runs and daily driving.
Engine Integration and Performance Gain
The 1.875 inch primary tubes are sized to improve exhaust flow velocity, reducing backpressure and enabling faster scavenging of burnt gases. This results in cleaner air intake and a more efficient combustion cycle, offering measurable gains in both low-end grunt and top-end horsepower. Pairing with MuscleRods mount kits ensures the engine sits at the correct height and angle, maintaining proper driveline alignment and reducing stress on transmission bellhousing and universal joints.
Material and Coating Advantages
Each header is finished in a silver ceramic coat that blocks radiated heat and shields against corrosion on the tube exterior. By keeping underhood temperatures lower, you protect sensitive wiring, fuel lines, and intake components from heat soak. Inside, the ceramic layer prevents surface oxidation under thermal cycling, preserving smooth exhaust passage over repeated use. The 0.375 inch thick flanges are precision machined flat to guarantee a leak-free seal when torqued, resisting distortion under extreme thermal load.
Balanced Design and Installation
The mid length configuration strikes a balance between full-length tube performance and ground clearance found in short styles. It provides increased torque below 4,000 RPM without risk of scraping on lowered suspensions or damaged crossmembers. All necessary hardware - gaskets and bolts - is provided in the box for a bolt-on assembly that aligns perfectly with factory and aftermarket mid-pipe systems. This makes it ideal for enthusiasts seeking a reliable, bolt-in solution that enhances exhaust efficiency and preserves underbody clearance.
With precision fitment and a ceramic finish that resists heat and corrosion, these headers deliver reliable exhaust flow and straightforward installation confidence.
