I'm just about to replace my entire exhaust system as i have just messed mine up. I am looking at different headers and such for a replacement for my current stock one. I have found a slightly used Spoon header but i am not sure if it will fit my B18B. I have heard that the bolt pattern is universal on some headers (Spoon, Toda, T1R, Fujitsubo, JUN, AN-R). I have never seen any of these headers in person and I'm not sure this is truly the case or not. On the sites that sell these products, none of them refer to the header being specific for a B18C or B18A...

Can anyone give me a straight answer?

 

I believe that any b-series header will bolt up to any b-series head. The problem arises when you attempt to put a B16 header on a B18 motor because of the difference in deck heights; however, I've heard of a couple people who have made that work as well.

How much you want for your stock header?

 

yeah header bolt patterns are the same.....the only thing i see gettin in the way is that some headers are longer then others. so i guess you would have to have a exhaust made custom for you....

 

hopefully sk8rmike can hook that up

thanks for the input guys

 

fuck a header...u dont need that shit...

 

let me guess turbo manifold?

 

haha i wish, im JDM so i dont roll with a header...

 

yeah swing by

 

WTF!?!

Anyway, you should be able to use any header but you do have to watch out for what it is made for b/c of the Deck Height! B18a/b/c1/c5 are all the same deck height.

I have a JDM ITR 4 to 1, but had to modify my oilpan to make it fit, but never had that problem before. Im about to go with an AN-R standard header(same as RMF).

BTW, I have a B18b
