1-7/8 Ceramic Coated Mid-Length Headers for 1991-1996 B-Body LS Swaps
If youre swapping an LS powerplant into a 1991 to 1996 B body chassis and find standard manifolds run into the crossmember or steering column, these one and seven eighths inch ceramic coated midlength headers provide the clearance you need while keeping exhaust gases flowing efficiently. Beneath the hood space is conserved by routing runners along the frame rails for precise port alignment and uniform exhaust velocity across all cylinders. Silver ceramic finish retains heat in the tubes to reduce underhood temperatures and shield wiring hoses from thermal damage. Installation is straightforward with precision flanges three eighths inch thick plus matching gaskets and bolts for a leak free seal right out of the box.
Precision Engineered Mid Length Tube Routing
The 1 7/8 inch diameter primary tubes are meticulously bent to follow the factory frame rails on 1991–1996 GM B-Body chassis, ensuring exact port alignment with LS cylinder heads. This close tolerance routing maintains uniform exhaust velocity across all cylinders, which enhances scavenging at low to mid engine speeds and avoids pressure spikes. By clearing the crossmember and steering shaft without cutting or grinding, these headers offer a direct bolt-in solution that preserves chassis integrity. The smooth mandrel bends support consistent flow dynamics, delivering responsive torque delivery under street or track use.
Advanced Ceramic Coating for Thermal Management
A robust silver ceramic layer bonds to each steel runner, acting as a thermal barrier that reflects radiant heat back into the exhaust stream. This trapped heat accelerates gas pulse velocity, improving throttle response and boosting low rpm torque while reducing underhood temperatures. The finish resists chipping, corrosion, and fading through countless heat cycles, protecting wiring, hoses, and firewall components from thermal damage. By keeping heat inside the tubes, this coating also minimizes heat soak during idling or heavy load driving, preserving both performance and component life.
Solid Steel Flanges and Complete Installation Hardware
Each header features a 3/8 inch thick steel flange that is precision machined flat to eliminate warping under thermal stress and ensure a reliable seal against LS cylinder heads. Exact bolt‐hole alignment prevents binding and simplifies installation, while the included gaskets and mounting bolts provide everything needed for a leak-free fit. This comprehensive kit approach reduces downtime and eliminates extra parts searches, letting builders focus on tuning performance. The rigid flange interface also prevents exhaust leaks that can sap power, ensuring smooth, quiet operation mile after mile.
These headers are precision built for a leak-free fit and reliable performance on your LS swap.
