Tight Tubes

Specifications:
Big power Hedman offers two header styles for street rods. Low-profile Block Huggers are great for accommodating narrow framerails to help eliminate many fit problems you might otherwise encounter with standard headers. The design of Tight Tubes is also for space-limited street rod applications but with Hedman's exclusive 4-into-1 Flat Collector that produces the same horsepower as standard headers.
