1977-1990 B-Body 1-7/8 Ceramic Coated Mid-Length LS Headers
When retrofitting an LS engine into a 1977-1990 GM B-Body chassis, you need headers that blend clearance and flow with precision and these 1-7/8 inch ceramic coated medium length units solve that exact challenge. Crafted from mandrel bent tubing with sturdy 3/8 inch flanges, they ensure a precise fit for your conversion project while channeling exhaust gases smoothly for increased torque and horsepower. Installation stays straightforward thanks to compatibility with direct fit LS mount kits and the ceramic coating guards against heat and corrosion over time.
Durable Steel Construction with Ceramic Barrier
These headers are built from robust steel that stands up to the extreme heat cycle of an LS powerplant and the demanding conditions under the hood of a B Body chassis. The applied ceramic barrier reduces radiant heat transfer by reflecting temperatures back into the exhaust path, which supports consistent air intake temperatures and protects surrounding components from heat soak. Over time the coating resists surface corrosion and maintains a fresh look even after repeated thermal cycling. The result is a durable assembly that combines structural integrity with thermal management in one package.
Precision Flange Fit for LS Engine Conversion
The thick 3/8 inch flanges deliver a precision mating surface that aligns exactly with LS head ports, eliminating exhaust leaks and simplifying the conversion process. Each port opening matches the factory bolt pattern so the installer can work without extensive modifications or custom adapters. When paired with the direct fit mount kit, these headers drop into place and clamp down securely, offering a steady seal under high exhaust pressures. This attention to fitment ensures you spend more time driving and less time troubleshooting gasket failures.
Flow Dynamics Boosting Output and Tone
By channeling spent gases through primary tubes with a 1.875 inch diameter, these headers optimize exhaust velocity and scavenging across the rpm range. The tuned medium length path balances low end torque with top end power, yielding strong throttle response at highway speeds and during launch off the line. As exhaust pulses exit cleanly, they merge smoothly in the collector and produce the deep rumble that B Body enthusiasts crave. This carefully engineered flow pattern not only elevates overall horsepower but also reinforces that classic muscle car soundtrack.
