Hi guys, I just recently picked up this rare Tanabe limit ax 4-2-1 headers for b series. I'm just wondering if anyone knew what the outlet size was? I've searched all of google but couldn't get anything.

I was pretty confident that it'll fit my b16 with stock cat. but then the seller told me that if they didn't fit, to return them and he'll give me his dc headers. So now I can't really try them on because its winter and its really cold even in my garage.

 

You picked them up, so I'd assume you have them in hand. Get a tape measure and measure it?

 

Fair enough, just been lazy in this freezing weather and its in the garage. the flanges should line up to the flanges from the cat though right?

 

Why dont you put on some warm clothes and go find out? if it matches up...cool. If it doesnt...you already know it will be cut and weld time. Not that big of a deal.
