1-7/8 Ceramic Coated Mid-Length Headers for LS Swaps on 1991-1996 B-Body
When fitting an LS powertrain into a 1991 to 1996 B Body the tight space around the crossmember and steering shaft demands precision; these ceramic coated mid length headers address that by tracing the factory frame rails and aligning ports for smooth exhaust pulses. By matching the common LS mounting bolt pattern the headers install in minutes with minimal clearance checks. The ceramic finish holds heat within the tubes and shields wiring and hoses from underhood temperatures. Each 3/8 inch flange is machined flat to hold gaskets firmly in place and stop leaks for quiet, consistent operation across every rpm range.
Advanced Ceramic Coating for Thermal Isolation
The silver ceramic layer applied to each header tube creates a thermal barrier that reflects radiant heat inward toward the exhaust stream while isolating engine bay components from extreme temperatures. By retaining heat inside the tubes scavenging pulses remain strong which improves low end torque and throttle response. This finish also resists rust and abrasion to extend service life under repeated heat cycles and helps protect wiring and hoses from heat damage.
Precision Engineered Mid-Length Tube Layout
Each header uses 1 7/8 inch diameter tubes precisely contoured to match LS cylinder head ports and maintain uniform gas velocity across all cylinders. The mid length design positions collectors close to the factory frame rails and guides exhaust pulses for efficient scavenging. This configuration yields smoother flow transitions, reduced back pressure at higher engine speeds, and a noticeable improvement in engine efficiency throughout the rpm range.
Robust Steel Flange Construction for Seal Integrity
A 3/8 inch thick steel flange is machined flat to ensure a consistent gasket seal against the cylinder head. By resisting warping during heat cycles these flanges prevent leaks that lead to noise, power loss, and exhaust intrusion into the engine bay. The sturdy steel construction adds durability and strength for long term use, and precision drilled bolt holes align perfectly with LS mounting patterns for a reliable seal.
Direct Fit Integration with LS Mount Kits
These headers are optimized for direct fit installation on a 1991 to 1996 B Body chassis when used with common LS mounting kits. The included gaskets and bolts simplify assembly and reduce the need for aftermarket parts, cutting labor time. Carefully designed routing provides clearance around the crossmember, frame rails, and steering components so no grinding or rerouting is required, making the swap process fast and straightforward.
