are the bolt patterns of the exhuast manifold the same on a b18c as they are on a b20b?

 

I believe they are, but i'm not 100%, I think the only difference is overall length of the manifold

 

b series exhaust bolt patterns are the same

 

when you say the overall length of the manifold what do you mean by this? like the length or how far out it sticks out back by the cat? because my problem is my car is a theft recovery and i am putting in a b20 but the entire exhaust system is gone and i was told when i replace the components i need to replace them from the same year integra as the cats are diff lengths. i was just thinking about ordering my stuff fro a 94 gsr because that is what it is but i didn't want the bolt pattern to be different on the head.

 

A complete '94 GS-R exhaust setup will fit just fine.

 

ok thanks alot. the help is much appreciated.
