Advanced Tri-Y Header Technology for Dirt Late Models

Take your Small Block Chevy Dirt Late Model to the next level with these Beyea Tri-Y headers. Engineered for engines equipped with 23-degree heads, this Tri-Y design utilizes a sophisticated stepped primary configuration—transitioning from 1-3/4 to 1-7/8 to 2 inches—to significantly enhance exhaust scavenging across the entire RPM range. This results in a broader, more usable power band that is essential for dirt track racing.

Technical Specifications

  • Application: Small Block Chevy with 23-degree heads
  • Design: Tri-Y configuration for improved torque and power
  • Primary Sizes: Stepped 1.75 to 1.875 to 2 inch
  • Collector: 3.5-inch collector for maximum flow
  • Finish: Durable black paint
  • Includes: Gaskets and mounting hardware

The Tri-Y design is renowned in racing circles for its ability to increase low-end torque and mid-range power, making it the ideal choice for tracks that require frequent acceleration out of corners. By pairing the cylinders in a specific sequence, these headers minimize exhaust pulse interference, allowing the engine to evacuate cylinders more efficiently. The large 3.5-inch collector ensures that even at high RPM, there is no restriction to exhaust flow. Built with high-quality steel and finished in a protective black paint, these headers are designed to handle the harsh conditions of the dirt track while providing consistent, reliable performance. Upgrade your race car's exhaust system with the precision engineering of Beyea, available at GGCRACING.
