1-7/8 Ceramic Coated Mid-Length Headers for LS Engine Swaps
When installing an LS into a 1968 to 1972 A-Body classic the tight fit around the frame rails and steering assembly calls for a header set built to exacting specifications. These 1 7/8 inch ceramic coated mid length tubes use GM specific flanges and precise port alignment to clear suspension components without any trimming or bending. A ceramic finish holds radiant heat inside the exhaust stream reducing underhood temperatures and preserving nearby wiring. Optimized primary diameter and routing balance low rpm torque with strong high rpm flow for a broad power band on both street and track.
Superior Ceramic Coating for Underhood Heat Control
These headers feature a high-temperature ceramic finish that reflects radiant heat back into the exhaust stream, keeping underhood temperatures in check. By maintaining warmth inside each primary tube, exhaust gases accelerate more rapidly and face less backpressure as they exit the manifold. The coating also acts as a barrier against corrosion on the steel substrate and minimizes thermal fatigue during repeated heat cycles. Cooler bay temperatures protect nearby wiring harnesses, intake plumbing, and electronic sensors, ensuring reliable operation in all driving conditions. This thermal management strategy translates to more consistent performance on both street and strip.
Optimized 1-7/8 Inch Primaries for Broad Torque Delivery
The choice of 1-7/8 inch primary tubes strikes a deliberate balance between low-rpm grunt and high-rpm freedom, shaping a wide power band that suits daily cruising and spirited acceleration alike. At low engine speeds, the slightly smaller diameter fosters stronger scavenging, improving throttle response and torque off the line. As the engine revs climb, the same sizing still allows ample flow to support peak horsepower without choking the exhaust pulses. Cyclists will notice smoother transitions through the powerband, while combustion efficiency improves fuel economy across the entire engine speed range. This tailored geometry delivers tangible gains in both driveability and performance.
Robust Steel Construction with Precision Mandrel Bends
Constructed from thick-wall steel, these mid-length headers resist warping and cracking under extreme thermal and mechanical stress. Each bend is formed by mandrel bending, preserving a consistent internal diameter and smooth surface that prevents flow disruptions and turbulence. The 3/8 inch flanges are machined flat to ensure a leak-free seal against the cylinder head, even when subjected to high exhaust backpressure and thermal expansion. This marriage of heavy-gauge material and precise fabrication guarantees long service life and dependable sealing in demanding swap applications. Installers benefit from a worry-free fit that maintains its integrity throughout thousands of heat cycles.
Precision engineering and ceramic protection ensure these headers deliver consistent performance and durability for your LS swap.
