Description of Dougs Headers D334 Metallic Chevrolet
Thick flanges (3/8 inch to 5/8 inch) with no warping. CNC mandrel bent tubes for an accurate fit and a better flow. Precision formed long transition collectors that reduces backpressure. Heavy gauge tubing (16 and 14G) for longer life. Header tubes are pre-polished for a better appearance.
fit perfectly they work on my Brodix Track One thanks for a great product. thanks dougs! I've been looking for a head to match this combo for a long time and was told I would have to custom make it for around 2500.00.
