Anyone recognize this header? Trying to determine if I fix the crack and put it up for super cheap, or take it to the landfill.

Doesn't look exactly like either of those. Maybe it is an early RB? Do they gusset the collection now?

I don't think ebay uses a 1/2" thick flange like this one has. Also, the flange looks like it's cast? The little studs that the primaries are welded to.

 

ebay header for sure.

 

Why do you think this? It looks nothing like my Raceland I have in the basement. It also has a matching catalytic converter. All stainless. Also Raceland uses 3/8 flanges. This is all 1/2"

 

Raceland is only one manufacturer of 4-1 miata header. This is a generic ebay unit and how i know is that it matches the one i have in the garage exactly. One thing to notice is the multi piece welded together collector.

 

also, the weld there on the pipe for cylinder 4 just a couple inches past the flange.

 

Trash can it it then.
