LT Ceramic Coated Long Tube Headers for 1971-1976 Impala and Caprice
For drivers completing an LT engine swap in a 1971 to 1976 Chevrolet Impala or Caprice B Body chassis, the 1971-1976 B Body LT Series 1.875-inch Ceramic Coated Long Tube Headers deliver the exact fit and heat management your project demands. Each header features 1.875 in tube primaries and 0.375 inch CNC machined flanges constructed from mild steel with a multi layer ceramic coating to contain radiant energy. Smooth MIG welds join the tubes and flanges, while included composite gaskets, high grade bolts, V band clamps and a dedicated mount kit provide all necessary components for installation. Manufactured in the USA, these headers set the foundation for a dependable exhaust system in your LT swap.
Enhanced Exhaust Flow with Precision Tubing
The 1971–1976 B-Body LT Series long tube headers feature 1 7/8 inch diameter tubes engineered for optimal exhaust scavenging and torque delivery. By extending the primary tubes beyond the factory exit, these headers promote smoother gas flow and better pulse tuning at midrange rpm. The larger tube size reduces back pressure and improves cylinder evacuation, which translates into stronger acceleration and cleaner exhaust scavenging. Every tube is formed to exact dimensions to ensure uniform length across all cylinders, delivering consistent exhaust wave timing for a balanced power band and throttle response.
Advanced Ceramic Barrier for Heat Management
Each header is finished in a multiple layer ceramic coating that reflects radiant heat away from the engine bay. This thermal barrier not only lowers underhood temperatures by up to 50 percent compared to bare steel, but also protects surrounding components such as intake manifolds, hoses and wiring looms. Cooler intake charge temperatures help the LT engine maintain optimum volumetric efficiency, while keeping ancillary systems within safe operating limits. The ceramic finish also resists chipping and abrasion, ensuring long service life in demanding street and strip environments.
CNC Formed Flanges and Solid Construction
The headers utilize 3/8 inch thick flanges machined on a five axis CNC platform to deliver perfect flatness and surface finish. This precision guarantees a leak resistant seal against the LT head exhaust ports, reducing the risk of header leaks and hot gas corrosion. Constructed from premium mild steel, the headers feature smooth MIG welds that maintain full metal penetration without burn through or undercut. Such weld integrity prevents fatigue cracking over repeated heat cycles while retaining structural strength under engine torque loads.
Factory Alignment and MuscleRods Integration
These long tube headers are engineered for direct fit installation on LT engine swaps into 1971–1976 B-Body chassis. All mounting points align with original bolt patterns for a no hassle drop in that preserves frame and steering link clearances. Integration with MuscleRods chassis mounts ensures proper engine placement and precise drivetrain angles, maintaining transmission alignment and reducing driveline vibration. Proudly made in USA, this reliable header set is a complete solution for enthusiasts seeking improved power, cooler engine bays and easy installation.
Backed by precision CNC flanges, MIG welds, and multi layer ceramic coating, these headers ensure consistent exhaust flow and lasting reliability for your LT swap.
