1978-1988 G-Body Ceramic Coated 1-7/8in Long Tube Headers
When you swap an LS engine into a 1978 to 1988 G body, selecting a header that endures extreme temperatures and aligns precisely with factory exhaust ports is essential. These 1.875 inch long tubes promote smooth scavenging across the rpm band while lowering back pressure for a sharper throttle response. The ceramic coated mild steel construction helps contain radiant heat and reduces underhood temperatures to protect wiring and plastic components. Their precision fit design uses a 3/8 inch thick flange matched to LS cylinder heads for a leak free seal and straightforward installation.
Precision Flange Design for Accurate LS Alignment
The 3/8 inch thick flange is CNC machined to match LS cylinder head port spacing, ensuring a perfect seal without the need for manifold spacers or custom adapters. This precision fit reduces exhaust leaks by maintaining exact port-to-flange registration, which smooths gas flow and preserves peak torque output. Installers benefit from minimized interference with steering shafts and factory crossmembers, streamlining the swap process. Consistent alignment also helps maintain original chassis geometry and prevents exhaust turbulence that can sap performance.
Optimized 1 7/8 Inch Tubing for Enhanced Scavenging
With a 1.875 inch primary tube diameter, these headers strike the ideal balance between gas velocity and volume to promote efficient scavenging across the RPM range. By tuning the tube size to an LS engine's torque curve, back pressure is reduced and exhaust pulses merge smoothly for sharper throttle response. This optimized flow characteristic unlocks trapped energy in the headers and delivers stronger low-end torque and midrange power. Drivers will notice a more responsive engine feel whether cruising on the street or launching off the line.
Ceramic Coating Thermal Management
The ceramic coating serves as a thermal barrier, reflecting radiant heat away from the engine bay and lowering underhood temperatures to protect wiring bundles and plastic components. Internally, the finish retains heat within the exhaust gases, increasing flow velocity as they exit the primaries and reducing condensation that can lead to corrosion. This dual action of external cooling and internal heat retention extends the service life of the headers while maintaining consistent performance over extended mileage.
Durable Mild Steel Construction for Reliable Service
Constructed from premium mild steel tubing, these headers deliver strength and ductility to withstand repeated heat cycles without cracking. The robust material resists warping and holds flange flatness under extreme thermal stress, ensuring a leak-proof connection when paired with quality gaskets and V-band clamps. This combination of toughness and precise sealing provides long lasting durability, allowing enthusiasts to push their LS swap to higher power levels with confidence.
