How can I tell if my RB header is for a 4 port 13b or a 6 port 13b?
I am trying to sell a header and presilencer that came off a 86 13b and I have a guy with a 85 GSL-SE.
is an 85 and 86 13b the same?

It will work. They are both 6 port engines. The only later model 4 ports are all turbo models. Everything '84 and later NA (13B) are 6 ports.

I was thinking about getting your setup too for my car, but shipping that thing from Canada would be expensive.

Edit: one more thing.. this was in a '79 car, correct? Was the rest of the exhaust '79 or from a different year? The portion of the exhaust on the SAs are different, so I wonder if it will all bolt up.

I was thinking about that right after i poseted. I was just alittle mixed up as RB has two diffrent part numbers for these cars

The three parts I am selling are from the 86 and then the rest was stock after the mid pipe( It was all home made to hook up to the mid pipe)

Measure stud spacing. 12cm is for 12A, 13cm is 13B.

A header for a 2nd gen might have different degree bends than a 1st gen header. I know for a fact the REPU header has different angles than a 1st gen header.
