Hi guys, just tryin' to find out if a header from a B18 will fit the B16. Just wanna make sure they are interchangable before any purchases. Thanks.

bolt pattern is the same on all B series exhaust manifolds....the height of the engine from head to oil pan varies slightly so it may not fit on those conditions.....i dont know for sure what works and what doesnt though...

B16 and non-vtec B18 header are all the same, the GS-R ones are slightly shorter though.
