1 7/8 Inch Ceramic Coated Long Tube Headers for 1977-1990 B-Body
When rebuilding the exhaust system on a B-Body from 1977 to 1990, installers face the challenge of aligning header flanges and managing underhood heat. The CLEARANCE-1 7/8 long tube ceramic coated headers address both needs with flanges cut to factory dimensions and a ceramic barrier that holds exhaust heat within the tubes. Each stainless steel primary tube is engineered for precise fit, reducing installation time and preventing leaks. As exhaust pulses merge in the 1 7/8 inch primaries, drivers will notice improved midrange torque and crisper throttle response on both street and track.
Precision Fitment Tailored to 1977 to 1990 B Body Applications
Every primary tube and flange is machined to match the exact contours and mounting points found on 1977 to 1990 B Body frames. This precision geometry reduces the need for trimming or grinding and eliminates common misalignment issues that lead to leaks. Installers benefit from a streamlined process that aligns seamlessly with factory hardware, cutting installation time. The result is a reliable seal and consistent performance without the trial and error of custom fitting.
Advanced Ceramic Coating for Heat Management
The ceramic coating provides a robust barrier that retains exhaust heat within the 1 7/8 inch tubes, increasing gas velocity as it exits the engine. By keeping higher temperatures inside the tubes, the coating also lowers underhood heat, protecting wiring and intake components. This heat control extends the service life of the headers and surrounding parts while preserving performance consistency under stress. The result is optimal thermal management in both street and track scenarios.
Extended Primaries Designed for Superior Exhaust Flow
With 1 7/8 inch diameter tubes that extend beyond the header flange, these long primaries improve exhaust scavenging and minimize backpressure. The design encourages smoother pulse merging, unlocking additional torque in the midrange power band where B Body engines spend most of their time on the road. Drivers will notice a crisper throttle response and more immediate acceleration whether merging onto a highway or accelerating out of a corner. Dyno testing confirms measurable gains and a more engaging driving experience.
Corrosion Resistant Stainless Steel for Lasting Durability
Constructed from premium stainless steel, these headers resist rust and corrosion even under constant heat cycling and exposure to road elements. The metal maintains its structural integrity and resists warping, ensuring that gasket surfaces remain true over thousands of miles. Combined with the protective coating, this material choice delivers extended service life and consistent performance. The headers stand up to harsh environments without adding unnecessary weight to the chassis.
Built from stainless steel with a ceramic coat these headers offer a precise fit and dependable performance.
