1-7/8 Ceramic Coated Mid-Length LS Headers for 1991-1996 B-Body
When installing an LS engine into a 1991 to 1996 B Body, these one and seven eighths inch ceramic coated mid-length headers ensure precise alignment with factory port spacing to eliminate fitment issues and maintain ground clearance. Engineers have machined three eighths inch flanges to match LS mounting points and deliver a leak proof seal without the need for extra sealant. The durable ceramic layer reflects radiant heat away from components in the engine bay while guarding against corrosion during spirited street runs or daily driving. Technicians benefit from straightforward installation with a complete hardware kit that reduces setup time and preserves the integrity of wires, hoses and header surfaces.
Exact Flange Machining for Factory Port Alignment
These headers feature three eighth inch thick flanges that are precision machined to match the LS engine's factory port spacing. By guaranteeing an exact fit against the cylinder heads, the design eliminates common alignment issues and reduces the risk of exhaust leaks without relying on extra sealant. The rigid flange thickness maintains a uniform seal under thermal cycling, preventing warping and preserving torque on the fasteners. Installers benefit from a straightforward bolt-up procedure that cuts down setup time and avoids interference with nearby wiring and hoses. Precise flange engineering ensures the performance gains you expect from an LS swap are delivered from the moment the engine fires.
Optimized 1 7/8 Inch Tubes for Exhaust Scavenging
The one and seven eighth inch primary tubes are engineered to boost exhaust gas velocity and enhance scavenging efficiency across the rev range. This careful sizing creates a stronger midrange torque curve and helps free up horsepower by minimizing residual backpressure in the headers. Drivers notice sharper throttle response and a livelier sound character when accelerating through city streets or open highways. The consistent tube diameter also maintains balanced pulse tuning, which is critical for smooth engine operation and consistent cylinder evacuation. Together, these factors contribute to improved fuel efficiency and a more engaging driving experience without sacrificing low speed drivability.
Mid-length Header Architecture for Balanced Clearance
The mid-length design positions primary tubes above the frame rails, preserving ground clearance for uneven roads and speed bumps while retaining pulse tuning benefits. This layout offers a middle ground between short headers that struggle at low rpm and long runners that can scrape on obstacles. The ceramic coated surface reflects radiant heat back into the exhaust stream, lowering engine bay temperatures and protecting nearby components from heat soak. By routing tubes in a compact footprint, the system fits cleanly in the 1991–1996 B-Body engine bay and avoids interference with steering shafts and brake lines. Combined with the included gaskets and bolts, this header profile makes it easy to achieve both performance gains and practical daily drivability.
