LS Ceramic Coated Mid-Length Headers for 1991-1996 B-Body Vehicles
The 1991 to 1996 GM B Body LS 1 7/8 inch ceramic coated headers are designed to guide exhaust through GMs full size chassis while keeping underhood temperatures in check. Each primary tube features a uniform ceramic layer that holds heat inside the exhaust flow to reduce heat soak on nearby components. With flanges machined to three eighths inch thickness the headers seal cleanly against the cylinder heads for reliable back pressure and consistent scavenging across the rpm range. Installation is simplified by matching factory frame clearances and including gaskets and bolts so builders can focus on tuning their LS powerplant rather than sourcing hardware.
Precision Alignment for LS Engine Integration in 1991 to 1996 B Body
The mid length 1 7/8 inch primary tubes are shaped to match the frame rails and engine mounts of full size GM chassis, ensuring a precise fit that eliminates common interference points. By maintaining correct geometry from the cylinder head to the collector flange, these headers preserve consistent exhaust pulse timing and back pressure across the rpm range. Machined flanges at three eighths inch thickness provide a flat sealing surface that resists warping under thermal load, avoiding exhaust leaks that can rob efficiency. This focus on accurate alignment reduces installation errors and minimizes the need for manifold spacers or custom adapters, speeding up the swap process for builders.
Advanced Ceramic Coating for Effective Heat Management
A uniform silver ceramic barrier covers each tube to trap heat within the exhaust stream and lower underhood temperatures. This thermal control not only protects nearby components such as wiring harnesses and intake manifolds but also helps maintain hotter exhaust gas velocity, which enhances scavenging at higher engine speeds. The finish is designed to resist rust and pitting in moisture prone environments, preserving its integrity over repeated heat cycles without flaking or fading. Reduced external heat radiation also gives tuners a more stable environment, simplifying the tuning of ignition timing and air fuel ratios.
Robust Steel Construction to Withstand Thermal Stress
Every header body is crafted from high quality steel that handles extreme temperature swings without cracking or losing strength. The choice of material delivers reliable performance over extended use, while the three eighths inch thick flanges resist deformation and ensure a leak free joint against the cylinder head. Mid length routing balances pipe volume with chassis clearance, allowing the tubes to clear steering linkages and frame crossmembers on the B Body platform. The welded joints undergo precision inspection to guarantee uniform wall thickness and clean transitions that maximize exhaust flow.
Comprehensive Hardware Package for Streamlined Installation
Each set includes installation gaskets and high grade bolts pre selected to match the flange bore pattern, eliminating the need to source additional parts. This complete hardware package simplifies assembly and ensures correct fastener torque from the start, reducing the risk of leaks or misalignment during break in. Builders can focus on final tuning rather than hunting for obscure components, which saves shop time and reduces project costs. Clear instructions guide the user through each bolt pattern and torque sequence, ensuring consistent results across multiple installations.
