1-7/8 Ceramic Coated LS Mid-Length Headers for 1991-1996 B-Body
Fitting an LS engine into a 1991 to 1996 B Body often uncovers tight exhaust clearance and high underhood temperature and these 1 7/8 inch ceramic coated mid length headers are designed to solve both. Each tube is mandrel bent to route exhaust gases smoothly through the frame rails while the silver coating reflects heat back into the exhaust stream to protect wiring harnesses and intake runners. Precision machined three eighth inch flanges match the LS head bolt pattern and the included gasket and bolt kit delivers a leak free seal for reliable performance on every swap.
Ceramic Coated Finish for Effective Heat Control
The silver ceramic coated surface on these LS headers acts as a radiant barrier that reflects heat back into the exhaust flow, reducing the amount of thermal energy transferred into the engine bay. By lowering temperatures around wiring harnesses, intake runners and fuel lines the finish prevents premature degradation of heat sensitive components. The coating bonds permanently to the steel substrate and resists corrosion from road salt or moisture while maintaining its barrier properties after thousands of heat cycles. This stable thermal barrier helps preserve consistent air charge density and reduces the risk of heat related detonation under heavy load. Over time the finish also protects the tubes from oxidation and keeps the headers looking as fresh as the day they were installed.
Mandrel Bent Tubes for Optimized Exhaust Flow
Each primary tube measures 1.875 inch in diameter and is mandrel bent to a smooth radius that maintains constant cross sectional area and minimizes turbulence. The precise length matching of each runner synchronizes the pulsed pressure waves that extract spent gases from the combustion chamber, a process known as scavenging. Enhanced scavenging directly translates to measurable gains in torque at low rpm and horsepower at high rpm by improving cylinder filling on the intake stroke. The routing is carefully designed to clear the 1991 to 1996 B Body frame rails without sharp turns or flattening that can disrupt flow. Consistent pulse timing also smooths out torque dips for a more linear power delivery when accelerating through the midrange.
Precision Steel Flanges Ensuring Leak Free Joints
The flanges on this header set are CNC machined from high quality steel plate to a uniform thickness of three eighth inch, providing a flat mating surface that exactly fits the LS head bolt pattern. By eliminating warpage the sturdy steel resists distortion under repeated thermal cycles and maintains a reliable seal without the need for constant retightening. When used with the supplied multi layer gaskets the precision flange geometry prevents exhaust gas leaks that can sap power and generate excessive under chassis noise. Consistent clamping force also keeps combustion pressure contained in the proper channels, reducing the risk of manifold cracks and cylinder head damage. This level of mechanical accuracy contributes to longer header life and uninterrupted engine performance.
Complete Installation Hardware Kit for Streamlined Assembly
Every header set includes the exact gaskets and grade specific bolts required for a 1991 to 1996 B Body LS swap, removing the need to source parts separately. The gaskets use a high temperature composite core that conforms perfectly to flange surfaces for an immediate seal upon installation. Grade eight mounting bolts are matched to engine block threads to ensure proper torque values and resist shearing under vibration. By providing a one package solution installers can save time and avoid common fitment issues related to mismatched hardware. This streamlined approach not only speeds up the assembly process but also minimizes error points, allowing you to focus on tuning the engine instead of troubleshooting leaks.
This header set ensures a precise fit and dependable performance throughout your LS swap.
