Doug's Headers D3348 LS Swap Full-Length Exhaust Headers for GM C10 Trucks

Transform your classic GM C10 truck's LS swap with these high-performance full-length exhaust headers from Doug's Headers. Specifically designed for LS-series engine conversions in 1963-1972 C10 and compatible GM full-size trucks, these headers are engineered to unlock significant power gains and improve exhaust flow.

Engineered for Performance:

  • Vehicle Fitment: Perfectly suited for 1963-1972 GM C10 and other full-size trucks undergoing an LS engine swap.
  • Primary Tube Size: 1.875-inch diameter primaries promote excellent exhaust velocity for increased horsepower and torque across the RPM range.
  • Collector Size: A 3-inch collector diameter ensures efficient exhaust gas evacuation, further enhancing engine performance.
  • Construction: Built from durable steel, these headers are designed to withstand the rigors of daily driving and performance use.
  • Coating: Finished with a Silver Ceramic coating that provides excellent heat management and a sleek, lasting appearance.
  • Design: Full-length design optimizes exhaust scavenging for maximum power output, especially in swapped applications.
  • Package: Comes as a complete pair for a straightforward installation.

By optimizing exhaust flow, these Doug's Headers headers allow your LS engine to perform at its peak. The full-length design helps to create a scavenging effect that pulls exhaust gases out of the cylinders more efficiently, resulting in more power and a more aggressive exhaust note. The silver ceramic finish not only looks great but also helps to insulate the engine bay by reflecting heat away. Elevate your C10's performance with the quality and engineering of Doug's Headers.
