Can anyone tell me for sure what this header is for? It has to be for a 13b FB, but is it just for the GSL-SE? I thought so, but then I saw that there are several 13b headers on the RB website.
It's definitely for a 13b motor, and it's about 34" end to end.

BTW if anyone wants it, make me an offer. I don't have a gasket for it, and it does have some discoloration, but has no damage and is in otherwise good condition

 

all 13b's are the same... a 13b header is a 13b header, unless of course you have a TII...

 

how about 100 shipped to 99224?

 

sure, but how would payment work?

 

not quite so.. the headers for 6-port motors are slightly different than those for a 4-port. they flow the same, but the bend is slightly different (to clear the six port actuators).. try putting one that was made for a 4 port motor on a six port motor (one that has the stock intake and functioning actuators) and you will see what i mean.

 

 

Note this:

would that not eliminate 4-ports?

I guess I shoulda been more clear. Whenever I think of a 13B, I just think of N/A engines...

 

When I think of 13Bs, I always think of the old 4-ports, myself. Guess that comes from driving an RX4 for a few years before I ever got an RX7.

 

That header looks "modified".

 

this is what i usually think as well, as my first rx7 was powered by a 13b from an rx4.
