Will it fit? I'm pretty sure I saw a topic before on here but at the time I wasn't concerned about headers. I tried searching but had no result.

 

b18c from a type-r or a gs-r? And what year?

 

I'm thinking he means a GSR?

 

I think he means ITR. And I have no clue.

 

if it's a type-r, yes it will fit. GS-R, it depends on the year.

 

All of the exhaust manifold studs/bolts will line up with any B series head, except for the prelude. The problem is bolting the header to the cat, this seems to be the difference. I have a B18B and am building and LS/VTEC with CTR head, Im gonna use a DC header for the B18B.

 

Alright thanks for the help. I was thinking of getting the DC JDM 4-1 which I have only found for VTEC models of the engine. I would go with something else but DC is in my price range at the moment and it has the 2.5 collector.
