Mid-Length Ceramic Coated Headers for 1991-1996 B-Body LS Swap
Tight clearances beneath the 1991-1996 B-Body chassis demand a header design that threads through the crossmember and steering shaft without interference while delivering robust exhaust flow. These 1-7/8 inch ceramic coated mid length headers trace factory frame rails and port alignment to simplify LS swap installation, while the silver ceramic finish retains heat inside the tubes to shield surrounding wiring and hoses. A 3/8 inch steel flange is machined flat for consistent gasket sealing, preventing leaks and noise across every rpm range for reliable operation on the street or track. Installation is further streamlined by including all necessary gaskets and bolts so mechanics can install these headers quickly and focus on dialing in engine performance.
Optimized Tube Routing for LS Swap Chassis Fit
Tightly packed spaces beneath the 1991 to 1996 GM full size chassis demand precise exhaust pathing, so the mid length header tubes trace factory frame rails and match cylinder head port geometry exactly. Each 1 7/8 inch diameter tube is carefully bent to maintain uniform gas velocity, balancing flow pulses from all cylinders. This approach enhances scavenging efficiency at lower rpm while ensuring clearance around steering linkages and the frame crossmember. By following OE routing cues, these headers reduce the need for modification and streamline the fitment process.
Ceramic Coating Enhances Thermal Control
A durable silver ceramic layer bonds over the steel tubes to create a thermal barrier that reflects radiant heat toward the exhaust gases and limits temperature rise in the engine bay. By retaining warmth inside the runners, the coating accelerates exhaust gas velocity, improving throttle response and torque delivery. It also resists fading, chipping, and corrosion through repeated heat cycles, offering lasting protection for nearby wiring, hoses, and firewall components.
Precision Flanges for Consistent Sealing
Each header features a 3/8 inch thick steel flange machined flat to ensure uniform gasket compression against the cylinder head surface. This rigid interface resists distortion under high heat and pressure, preventing exhaust leaks that can cause noise and sap power. Bolt holes are located to match LS head patterns exactly, eliminating stress points and ensuring a stable, maintenance free seal over thousands of driving miles.
Complete Hardware Kit for Faster Assembly
To simplify installation, the headers arrive with all required gaskets and mounting bolts in the correct sizes for common LS engine conversions. Supplying these components together cuts parts searches and reduces downtime during engine swaps. With precise tube geometry and flanges already aligned to LS mounting patterns, mechanics can install the headers quickly, focus on final tuning, and move on to performance calibration without added fabrication.
Precision fitment and durable construction make these headers the dependable choice for your LS swap.
