LS Swap Exhaust Header for 1963-1982 Chevy Corvette
Connecting an LS engine to a 1963 to 1982 Corvette frame demands careful header selection to control bay temperatures and keep exhaust gases flowing with minimal restriction. These ceramic coated headers feature 1.875 inch primary tubes that act as a thermal barrier to reduce heat soak and use tuned collector geometry to smooth pulse overlap for midrange torque and the classic Corvette growl. Machined 0.375 inch flanges align with GM mounting points and include all necessary gaskets and hardware so you can avoid custom fabrication and seal the system leak-free from the start. By lowering underhood heat, preserving exhaust flow consistency and eliminating leaks, this assembly supports reliable performance whether you are cruising city streets or pushing your Corvette on track.
Precision 1.875 Inch Tube Design Enhances Flow and Torque
The headers feature 1.875 inch primary tubes that strike a balance between gas velocity and volume. This diameter ensures exhaust pulses merge smoothly in the collectors, boosting midrange torque without sacrificing top-end response. Tuned collectors use specific angles to reduce pulse interference and maintain a strong note that echoes the Corvette heritage. By optimizing tube length and bore, these headers deliver a refined power curve for both street use and spirited driving.
Rigid Steel Construction with Machined 0.375 Inch Flanges
Made from robust steel, each header tube and flange remains stable under intense heat cycles and constant vibration. The 0.375 inch thick flanges are machined flat to match GM mounting surfaces, preventing warping that can cause exhaust leaks and power loss. A precise seal across the cylinder head ports preserves uninterrupted exhaust flow, which supports consistent horsepower delivery. The sturdy build withstands repeated stress and helps maintain performance over years of use.
Ceramic Coating Delivers Underhood Heat Management
A ceramic barrier finish on the tubes reduces radiant heat by acting as an insulator between the exhaust path and the engine bay. Lower bay temperatures protect critical components such as intake runners, wiring looms and rubber hoses from heat related wear. This thermal control also helps maintain denser intake charge temperatures for improved combustion efficiency. The abrasion resistant surface retains coating integrity through repeated thermal cycles, ensuring long term durability.
Direct Fit GM Mounting for Streamlined LS Integration
These headers align perfectly with GM mounting bosses on Corvette frames from 1963 through 1982, eliminating the need for adapters or custom fabrication. Included gaskets and hardware allow a straightforward installation process that reduces downtime and labor. Exact port alignment ensures a tight contact surface and instant leak free operation from first startup. This direct fit approach simplifies LS engine swaps and supports reliable exhaust flow across builds.
