1977-1990 B-Body LS 1-7/8-Inch Ceramic Coated Mid-Length Headers
Tackling an LS swap on a GM B-Body often means balancing exhaust clearance and flow, and these ceramic coated mid-length headers with 1.875 inch primaries deliver the tailored solution your project demands. They use mandrel bent tubing and sturdy three eighths inch flanges to create a precise seal at the cylinder head, cutting out exhaust leaks that slow down your build. Installation stays straightforward thanks to direct fit mount kit compatibility and the ceramic barrier coating keeps heat in the pipes and out of the engine bay. The result is stronger torque delivery across the rpm range and the deep rumble B-Body enthusiasts look for.
Steel Construction with Ceramic Barrier Management
These headers use durable steel tubing that withstands repeated heat cycles typical of LS applications. The ceramic coating reflects thermal energy back into the exhaust stream to support stable intake air temperatures and reduce heat soak in the engine bay. Over time this treatment also prevents surface corrosion to maintain a clean appearance. Combined, the material and coating deliver a robust assembly that balances structural strength with effective heat management.
Precision Flanges Ensuring Leakproof Seal
The three eighth inch flanges match LS cylinder head bolt patterns to align port openings exactly and eliminate exhaust leaks at the source. This precise fit means installers face fewer adjustments or gasket issues during a conversion project. When paired with compatible mount kits the headers clamp securely under high exhaust pressure, ensuring consistent performance and less time spent on troubleshooting. As a result, you gain a reliable seal that holds under torque pulses throughout the rpm range.
Optimized Exhaust Flow for Torque and Tone
Featuring 1.875 inch primary tubes, these mid length headers balance exhaust velocity and scavenging for stronger low RPM torque and stable high RPM power. As exhaust pulses exit the collector smoothly they reinforce a deep rumble that complements the B body acoustic character. This design not only elevates engine output but also preserves that classic muscle car soundtrack drivers expect. The tuned path delivers both functional gains and a signature sound experience.
These ceramic coated headers deliver reliable fitment and stronger torque for your LS swap on classic GM coupes.
