1-7/8 Ceramic Coated Long Tube Headers for LT Engines on 1971-1976 Impala/Caprice B-Body
When tackling an LT engine swap in a 1971 to 1976 Impala or Caprice B Body chassis these 1 7/8 inch diameter long tubes deliver precise routing and consistent heat containment for a smooth fit. Featuring CNC cut flanges that match the LT port pattern they create a leak resistant seal against the cylinder head surface. By trapping radiant energy inside the primaries the multi layer ceramic coating lowers underhood temperatures and shields adjacent wiring and hoses from premature aging. Included composite gaskets bolts and V band clamps simplify installation so you spend less time hunting hardware and more time fine tuning engine accessories.
Advanced Ceramic Coating for Effective Heat Shielding
The multi layer ceramic finish applied to every mild steel tube reflects radiant heat back into the exhaust flow, preserving thermal energy within the primaries and boosting gas velocity for superior scavenging. By containing high temperatures inside the headers, underhood heat levels drop significantly, reducing stress on nearby wiring, hoses and intake components. This rigid coating resists cracking or flaking through repeated heating cycles, ensuring consistent performance over thousands of miles. The result is a stable thermal envelope that prolongs component life and supports reliable function in both street and track conditions.
Mandrel Bent Tubing for Smooth Exhaust Flow
Each primary tube is formed with precision mandrel bends that maintain a constant internal diameter through every curve, eliminating the turbulence and flow restrictions common in stamped or crush bent designs. Combined with premium MIG welds that fuse the tubes to the flanges with even penetration, this construction resists fatigue from continual thermal expansion and contraction. The welded seams remain robust under high heat cycles, delivering unrestricted exhaust flow that translates into improved torque and horsepower output. Drivers will notice crisper throttle response and a more energetic powerband across the RPM range.
CNC Machined Flanges Ensuring Leak Free Sealing
CNC precision cutting produces flanges that match the LT port pattern on 1971–1976 Impala and Caprice B Body heads with exacting uniform thickness to prevent warping under extreme temperatures. This tight tolerance fit ensures full surface contact against the cylinder head, eliminating exhaust leaks and the need for frequent retorquing. When paired with the included composite gaskets and V band clamps, installers achieve a reliable seal that maintains optimal backpressure and steady performance in all driving scenarios. Crafted in the USA, these headers deliver consistent quality you can count on.
Complete Hardware Package for Streamlined LT Installation
The kit arrives fully equipped with composite gaskets, high grade bolts and precision V band clamps to eliminate part hunting during your LT swap. Every fastener and seal is sized specifically for the 1971–1976 B Body chassis, ensuring a tidy engine bay and avoiding mismatched components. By providing all necessary mounting hardware, the package reduces install time and simplifies fitment, allowing builders to focus on accessory integration and tuning rather than sourcing bolts. This all-inclusive approach ensures a hassle free swap and a professional finish.
Engineered for a precise fit and reliable performance in your LT swap project, these headers provide the confidence you need for every mile.
