X2 I was just going to ask the same question??

They look like Melrose headers to me. I could be wrong though.

Looks great so far! What rear axle/differential are you using? I'm building a very similar car right now and I'm looking at getting the 9" from Strange...

Keep the updates coming.

The headers were made by Silver Panther Performance. They cost $188.83 plus $25.00 shipping. They are a 1 3/4 tube - 67/69 Camaro Ls-1 swap. My build is a budget build and they saved me $500.00 off the price of Hooker headers. The quality is OK, they have a few flaws but nothing so bad that one can see. These headers are the exact same design as the Hooker headers. On my car they gave me 4 3/4 inches of clearance. The clearance will depend on how high your car sits off the ground. These headers fit great,,,,but a corvette body is channeled to the frame and the body hits my headers, so I am going to sell these and buy something different, like a mid length header. The rear in is a narrowed nine inch ford with a Strange center section, 4;10 gear, and strange axles.

Melrose makes really great headers if you can afford them. I know a number of people that have them on late model cars and are very pleased.

Car is coming along nicely.
