Ceramic Coated 1-7/8in LS Mid-Length Headers for B-Body
When you swap an LS powerplant into a 1991 to 1996 GM full size chassis, underhood space leaves little room for traditional exhaust manifolds. These ceramic coated 1-7/8 inch headers follow the factory frame rails to clear the crossmember and steering shaft while preserving exhaust velocity through uniform tube bends. Installation comes complete with precision flanges, gaskets, and hardware so you can secure a leak free seal quickly and focus on tuning engine performance. By retaining heat within the runners, the silver ceramic finish limits underhood temperatures and protects wiring, hoses, and firewall components from thermal damage.
Optimized Tube Geometry for LS and B-Body Fitment
The 1 7/8 inch diameter primary tubes are bent to trace the factory frame rails beneath the 1991–1996 B-Body chassis, ensuring exact port alignment with LS cylinder heads. This precise tube routing maintains uniform gas velocity, enhancing exhaust scavenging at low to mid engine speeds while preventing back pressure spikes. Careful clearance around the steering shaft and crossmember means minimal modification is required, so fabricators can install these headers without trimming rails or relocating linkages. By following OE paths and matching head exit angles, the design delivers smooth torque delivery and helps maintain factory fitment tolerances for reliable operation under street or track conditions.
Ceramic Coating as a High Temperature Barrier
A durable silver ceramic layer bonds to each steel runner, creating a thermal barrier that reflects radiant heat toward exhaust gases and keeps underhood temperatures in check. Trapping heat inside the tubes accelerates exhaust pulse velocity, improving throttle response and low rpm torque. The finish also resists chipping, corrosion, and surface fading after repeated temperature cycles, protecting nearby wiring, hoses, and firewall components from heat damage. This protective shield helps maintain clean engine bay conditions and reduces the risk of heat soak when idling or during high load driving.
Precision Machined Flanges and Comprehensive Hardware
Each header flange is crafted from 3/8 inch thick steel and machined perfectly flat to ensure uniform gasket compression against the LS head surface. This rigid interface prevents warping under thermal stress, eliminating exhaust leaks that can cause noise and power loss. Bolt holes are drilled to match LS head patterns exactly, allowing bolts to sit without binding or stress. The headers come complete with matching gaskets and mounting bolts, so installers have all required components on hand. This comprehensive kit cuts downtime, avoids parts searches, and lets technicians focus on tuning rather than tracking down fasteners.
