1977-1990 B-body LS 1-7/8 Ceramic Coated Long Tube Headers
When swapping an LS motor into a 1977 to 1990 GM B body the factory exhaust manifolds can choke flow and rub against frame rails. These 1.875 inch ceramic coated long tube headers replace restrictive stock manifolds with uniform primary tubes that clear crossmembers and balance exhaust pulses for better torque delivery. A reflective ceramic finish cuts radiant heat in the engine bay while thick flanges milled flat secure a reliable seal at the head and a V band style collector prevents leaks under load. All gaskets and mounting hardware are included for a plug and play installation that saves time on your LS swap.
Uniform Runner Diameter for Optimized Scavenging
The straight 1-7/8 inch primary tubes maintain a consistent flow path that balances exhaust pulses across all cylinders. By equalizing pressure waves, this design enhances scavenging efficiency and minimizes backpressure, delivering smoother torque rise throughout the rev range. This careful tube sizing directly translates to sharper throttle response and broader power delivery, especially noticeable during midrange acceleration. The uniform geometry also simplifies tuning, allowing you to dial in the ideal air-fuel ratio without fighting uneven exhaust flow.
Ceramic Coating for Effective Heat Management
The reflective ceramic finish on each mild steel header dramatically reduces radiant heat transfer in the engine bay, keeping intake and ignition components cooler. By reflecting thermal energy back into the exhaust stream, the coating preserves gas velocity, which is critical for scavenging and overall efficiency. This surface treatment also resists oxidation and corrosion, ensuring the headers maintain their performance and appearance over thousands of miles. Cooler underhood temperatures mean more stable ignition timing and reduced risk of heat soak in demanding driving conditions.
Precision Machined Flanges for Leak Free Sealing
Each flange is a full 3/8 inch thick and is machined flat to guarantee uniform contact with the cylinder head. This robust sealing surface minimizes the chance of exhaust leaks under heavy load, maintaining consistent backpressure control for better fuel economy and performance. The precise fit reduces the need for excessive gasket compression and preserves torque readings during installation. Strong metal-to-metal contact extends gasket life, cutting down on maintenance and ensuring long-term reliability.
Integrated V Band Collector Ensuring Airtight Connection
The V band clamp style collector creates a secure, leak-proof joint that prevents exhaust gases from escaping under high boost or aggressive rpm. This design simplifies disassembly for service or further modifications, as the collector can be separated without removing the entire header assembly. The clamp system also maintains uniform clamping force around the flange, eliminating hotspots and ensuring a consistent seal. As a result, you'll enjoy reliable operation and reduced exhaust noise without the hassle of retorquing or gasket failures.
