Ceramic Coated 1-7/8in Mid-Length Headers for LS Engines
Facing tight frame rail and steering link clearances in 1968-1972 A-Body LS swaps, the 1968-1972 A-Body LS 1-7/8 Ceramic Coated Mid-Length Headers deliver a precise routing path that clears suspension components without sacrificing exhaust flow. Built with GM specific flanges and smooth mandrel bends, the headers achieve precision port alignment for a leak-free seal and offer bolt on installation with the included gaskets to avoid trimming. By capturing radiant heat inside the 1 7/8 inch primaries, the ceramic finish cuts underhood temperature, shields wiring and sensors from heat soak, and encourages consistent scavenging across the rev range.
Durable Ceramic Coating Controls Radiant Heat
The ceramic finish applied to each tube serves as a thermal barrier by reflecting radiant heat inward toward the exhaust stream. This retention of heat promotes faster gas exit and improved scavenging, reducing backpressure and smoothing power delivery across the rev range. By containing surface temperatures, the coating guards wiring, sensors and intake parts from heat soak in the engine bay. Over repeated heating cycles the protective layer also inhibits surface corrosion on the steel substrate and resists cracking during expansion and contraction, delivering reliable performance over time.
Precision Routing for A Body Frame Rail Fitment
Designed specifically for 1968 through 1972 A Body chassis, these mid length headers follow a carefully mapped path to clear frame rails and steering linkage without trimming or bending. GM specific flanges and precision port alignment ensure a leak free seal against factory cylinder heads, so installers can rely on factory bolt patterns and eliminate custom flange work. The mid length layout also balances collector placement with suspension geometry, preserving ground clearance and steering travel. This tailored routing cuts installation time while maintaining optimal exhaust flow.
Optimized 1 7/8 inch Primaries for Wide Power Band
Each primary tube measures 1 7/8 inch in diameter, a choice that balances low rpm torque with high rpm volume capacity. At low engine speeds the tube size supports strong momentum in the exhaust stream, sharpening throttle response and enhancing launch acceleration. As rpm climbs the same geometry supplies ample exhaust volume to sustain peak horsepower without excessive backpressure. The result is a consistent and broad power band that adapts equally well to street cruising and track demands.
Robust Steel Construction with Mandrel Bends and Thick Flanges
Fabricated from thick wall steel tubing, these headers employ mandrel bending techniques to maintain a constant internal diameter through each curve, eliminating turbulence and flow restriction. Precision machined 3/8 inch flanges provide a perfectly flat mounting surface for a secure, leak free connection to the head. Sturdy welds reinforce critical junctions and help prevent warping or fatigue under continual temperature cycling. Together, these elements form a durable foundation that withstands the rigors of daily driving and high load applications.
These headers deliver precise fitment and consistent exhaust flow for dependable performance in your LS swap.
