1-7/8 Ceramic Coated LS Mid-Length Headers for A-Body
Tackling tight clearance between frame rails and floor pan in a 1968 through 1972 A Body LS conversion these 1 7/8 inch ceramic coated mid length headers deliver precise routing and consistent exhaust evacuation across the rpm range. By using smooth mandrel bent steel tubes and machined three eighth inch flanges they match the LS head pattern without adjustment shims and lock in a leakproof seal. A ceramic barrier coating retains heat inside the primaries to lower underhood temperature and preserve intake charge density for stronger low rpm torque. Installers will value direct bolt up to popular LS swap mount kits so no bracket fabrication or grinding is required.
Ceramic Coating and Steel Construction for Enduring Performance
These mid length headers use heavy wall steel tubing selected for its ability to withstand high temperatures and resist warping during repeated heat cycles. Each bend is formed by a mandrel process that maintains a smooth inner surface to minimize flow restrictions and support consistent pulse scavenging. The silver ceramic coating applied to the exterior of the primary tubes acts as a thermal barrier that retains heat in the exhaust stream, reducing underhood temperature and preserving intake charge density. In addition to improving torque output at low rpm, this coating provides corrosion resistance and protects against road debris, ensuring the headers retain their finish over many seasons.
Machined Flanges Delivering Reliable Exhaust Sealing
Precision machined three eighth inch flanges ensure an exact match to the LS cylinder head bolt pattern, eliminating the need for adjustment shims and speeding up installation. The rigidity of a thick flange surface resists deformation under thermal expansion and exhaust backpressure, providing a consistent seal across the gasket. This reliable interface prevents exhaust leaks that can rob power and introduce unwanted noise under the hood. With included gaskets and hardware that meet factory torque specifications, installers can achieve a leakproof connection in classic GM B body engine bays with confidence.
Optimized Primary Tubing for Power and Tone
A one point eight seven five inch tube diameter was chosen to balance the velocity and volume of exhaust gases, improving scavenging and boosting torque across the mid rpm range. Smooth transitions into the merge collector help eliminate turbulence and pressure spikes, delivering a steady flow profile for both street driving and performance applications. The specific routing of each tube was engineered to navigate the frame rails and floor pan clearances of 1977 to 1990 GM B body chassis without modification. Drivers will notice a deep muscular exhaust note that enhances the character of an LS engine in a classic coupe or sedan.
Direct Bolt Up Compatibility with LS Swap Mount Kits
These headers are designed to mate directly with popular LS swap mount kits, aligning with existing frame brackets to eliminate the need for fabrication or grinding. Critical attachment points correspond precisely to industry standard for swap components, allowing technicians and home builders alike to focus on tuning rather than fitment challenges. Included grade specific bolts and OEM style gaskets ensure factory level performance from the moment of installation. The straightforward bolt up approach preserves undercarriage integrity and delivers a clean engine bay layout that simplifies future maintenance.
Engineered for a precise fit and reliable performance in your LS engine swap.
