LS Ceramic Coated Mid-Length Headers for F-Body
Swapping an LS into a 1970 to 1981 F body calls for headers that clear the steering shaft and crossmember without hassle. These 1 7/8 inch ceramic coated mid-length headers slip into the factory location and boast a silver ceramic finish that reflects underhood heat. They feature durable heavy gauge steel tubes that resist warping under thermal stress and flanges machined to stock thickness for a true bolt on seal and straightforward installation. You get reliable exhaust flow, lower bay temperatures, and a precise fit that keeps your conversion on schedule.
Robust Steel Construction for Thermal Stability
These headers are built from heavy gauge steel that retains its shape under repeated heating and cooling cycles. The substantial wall thickness ensures each primary tube maintains its intended profile, preventing distortion when temperatures climb under load. Welded junctions at the merge collector and flange are reinforced to avoid stress fractures over time, preserving the integrity of the exhaust path. This sturdy assembly delivers consistent performance whether the vehicle sees daily driving or spirited runs. The result is a system that resists warping and cracking, extending service life without the need for periodic realignment or repair.
Ceramic Coating as Reflective Heat Shield
A silver ceramic finish applied to the tube exteriors acts as a radiant barrier that sends heat back into the exhaust flow rather than into the engine bay. By cutting underhood temperatures by up to fifty percent, this coating protects nearby wiring, hoses, and intake parts from heat soak that can degrade performance. Retaining thermal energy inside the pipes also boosts exhaust velocity, which further aids scavenging and contributes to stronger midrange power. The ceramic layer resists oxidation and surface fatigue, ensuring the headers look and perform like new even after extensive high-temperature use. Over time, the finish helps preserve the metal beneath, preventing rust and flaking.
Optimized Primary Tube Geometry for Efficient Scavenging
The one and seven eighths inch primary tubes are carefully sized to match the exhaust pulse timing of an LS V8, promoting balanced scavenging across the rpm range. Smooth mandrel bends hold a uniform diameter through each curve, reducing internal turbulence and minimizing backpressure that can dull throttle response. Equally important, consistent tube length across all cylinders aligns pressure waves to reinforce exhaust evacuation, delivering stronger torque at low and mid engine speeds. This calibrated flow behavior unlocks measurable horsepower gains without sacrificing driveability on the street. It also ensures a more linear power curve, so throttle inputs feel predictable and responsive.
Precision Machined Flanges for Leak Free Installation
Each header flange is CNC machined to a precise three eighths inch thickness, providing a flat, true surface that mates exactly with factory exhaust ports. This dimensional accuracy eliminates common issues such as gasket blow-outs or exhaust seepage that occur when flanges warp or sit unevenly. Factory-style bolt holes line up with existing head studs, and included gaskets plus corrosion-resistant hardware let installers achieve a genuine bolt on fit without cutting or welding. The result is a fast installation process that maintains steering shaft and crossmember clearances straight from the box. Users can rely on a secure seal and trouble-free operation from the moment the engine fires.
