Anybody recognize what brand of header this is? Came with some other SA parts. Thanks in advance.

 

looks like a RB 12a header made to work on a 13b.

 

It was used on an early car for sure. Note the two round carbon spots on the flange. So we know it likely fits an early 12A. As far as a brand, I'm not sure. Rotary Engineering made some early stuff but I'm not certain this is their work.

 

i would have said Rotary Engineering too, they used that goofy 6 bolt flange too.

 

As far as I know, Racing Beat has always cut their initials into the mounting flange. Was hoping that someone might have the same piece who can verify the manufacturer. Could be a R/E part, I'll try doing a little digging in that direction to see what I can find. Thanks.

 

considering selling it?

 

There is a RE 12a header on epay right now. It has very similar flanges as yours (both ends) but not the 2-into-1 collector piece.

 

I third the Rotary Engineering- looks identical to mine. The heavy-wall steel should clean up nicely.

I used to have a RE header, looked a like this on. The 2 to one after the 6 bolt dual flange is fabricated by someone else.

 

Its definitely old and appears to be well made. I agree that the collector is home made.

 

A side note, a Rotary Engineering header will NOT bolt up to a Racing Beat long primary midpipe without a lot of work.
Thickwall tube is very hard to bend!

 

I think that is an old RB Road Race header...

 

IIRC, the 2 middle bolt holes on the outlet flange are offset opposite on RB vs RE, another reason it won't bolt to a RB mid section.
The RE tubes don't turn as sharply as the RB at the inlet.
Here's an NOS RE I sold years ago.

 

Here's the thread where I made it fit.
