Mid-Length Ceramic Coated LS Headers for 1991-1996 B-Body
Swapping an LS motor into a 1991 to 1996 B Body chassis requires carefully packaged exhaust runners that control underhood heat and maintain gas flow, and these mid length headers deliver on those demands. Engineered with 1-7/8 inch primary tubes to optimize scavenging and 3/8 inch thick flanges for a durable leak free seal they match LS small block ports without modification while promoting increased horsepower and low end torque for a more responsive driving feel. The silver ceramic finish traps heat inside the tubes to keep intake temperatures stable under load and also resists moisture and road salt to help preserve the steel surface in demanding conditions. Precision laser cut flanges and CNC formed bends simplify installation by preserving steering and brake line clearance.
Engineered 1 and 7/8 Inch Primaries for Optimized Exhaust Scavenging
The 1 and 7/8 inch primary tubes are sized to generate ideal pulse overlap, boosting exhaust scavenging and maintaining high gas velocity across the LS rev range. By fine tuning this diameter, back pressure is minimized, which translates into noticeable gains in both horsepower and torque from idle through redline. This precise tube sizing enhances low end response, giving drivers a more immediate throttle reaction in the 1991–1996 B Body chassis. The consistent flow under load also helps maintain exhaust gas temperature balance, contributing to overall engine efficiency. In addition, the uniform tube length and gentle bends preserve equal runner lengths, ensuring each cylinder contributes evenly to the power curve.
Ceramic Coating for Heat Control and Corrosion Protection
The high-temperature silver ceramic finish serves as an effective thermal barrier, keeping radiant heat inside the tubing and away from critical underhood components. This containment of heat helps preserve intake charge density, reducing the chance of heat soak under sustained operation. Beyond temperature management, the coating repels moisture and road salt, thwarting rust formation on the steel substrate in humid or coastal environments. A smooth, hard surface also makes routine cleaning easier by preventing grime adhesion. Overall this treatment extends header service life and maintains a clean appearance over multiple seasons of driving.
3/8 Inch Thick Steel Flanges Ensure Reliable Sealing
Flanges cut from 3/8 inch thick steel plate provide a stable, flat mating surface that resists distortion under high temperature cycling. This flange thickness supports consistent gasket compression, greatly reducing the risk of exhaust leaks during sustained highway runs or spirited acceleration. The robust steel construction withstands the vibration and chassis flex typical of the B Body platform, ensuring the mating surface remains true without the need for frequent retorque. In practical terms, this means fewer maintenance stops and a leak free seal that holds up under stress. The thickness also adds rigidity to the header assembly, preventing flange warpage even after repeated heat soak events.
Precision Laser Cut and CNC Formed Fit for Simplified Installation
Each header component is manufactured using laser cutting and CNC bending techniques to match LS small block exhaust ports with millimeter accuracy. This level of precision eliminates the need for grinding or port modification, resulting in a bolt on installation that aligns perfectly with factory mounting points. The routing of the tubes is optimized to clear steering shafts and brake lines, preserving safe hardware distances without additional adjustment. As a result, installation time is reduced and the potential for exhaust leaks from misalignment is virtually eliminated. Builders can proceed with confidence, knowing the headers will integrate seamlessly into the B Body engine bay and maintain factory driving geometry.
