Buick Nailhead 364-425 Exhaust Flange Straight Lake Header Kit

$150.00

Includes One Straight Lake Header Kit for the Buick Nailhead hot rod motor (see motor applications below).  These flanges are cut with a CNC HD (High Definition) Plasma cutter out of 3/8” Pickled and Oiled (P&O) steel.  P&O material is hot rolled steel that has been dipped in acid to remove the mill scale and then a light coated lightly with oil to prevent rusting.  The end result is less work to clean off the mill scale as needed with hot rolled mild steel.

 

Kit includes: 

1 pair – 30″ long steel megaphones (1-5/8″ inlet & 3-1/2″ outlet) – 4″ outlet available upon request

    I really didn’t know what to expect since the price was so awesome. The quality, craftsmanship and customer service is truly top notch. Saying outstanding is not saying enough. I have 4 more hot rods and they will all have exhaust from Hell’ Gate! Thank you!

    Oh and if you guys could make a flange for an Olds 394 i’d Make it 5 cars with your exhaust
