TIGHT TUBES have the flattest collector on the market! Exclusively from Hedman, these headers feature a unique 4-into-1 flat collector that produces the same power as a standard collector, while providing maximum clearance. Perfect for Street Rods and custom projects.

All Hedman street Hedders are MADE IN THE USA, and are backed by a lifetime warranty against manufacturing defects! HTC coated stainless models also available.

UNLESS SPECIFICALLY STATED, ALL HEADERS ARE DESIGNED FOR USE WITH FACTORY PROFILE CYLINDER HEADS!
If your engine does not have factory cylinder heads, we strongly recommend you contact the aftermarket head manufacturer to confirm that the deck angle, exhaust port height and spark plug angle/position match the factory cylinder head design, before ordering your headers. If you are still unsure, please contact the Hedman Tech lines M-F 8am-4:30PM (Pacific) @ (562) 921-0404.

IMPORTANT!: Installing coated headers on an engine during the break-in period will cause discoloration. We recommend the use of factory manifolds, or an old set of headers, during the engine break-in period.

 Designed for very restrictive space limitations, such as narrow framerails on street rods, early cars and trucks, TIGHT TUBES model hedders feature a unique 4-into-1 flat collector that produces the same power as a standard collector, while providing maximum clearance. The TIGHT TUBES collector is the flattest collector on the market today.

As with all Hedman Hedders, HEDMAN TIGHT TUBES are available with or without our HTC ceramic-metallic finish.

Built in the USA, and backed by Hedman's Limited Lifetime Warranty!
