Hi, i've currently got a '94' civic VTi, and want to get a 4 branch manifold for it, i've got one in mind, but i heard a rumour that you might have to take the engine out to fit it??? i found that hard to believe but could someone shed some light?? also could someone explain what the headers are i get confused really easily,
cheers Ben

 

four branch intake manifold?? If you're talking about the GSR IM, it won't fit.

as for what a header is It's the piece that connects to the engine block up front that routes the exhaust.

 

it brings it from 4 (cylinders) down to 1 for the exhaust prior to hitting th cat and muffler

 

yeah, sorry we call it the same thing header/manifold, sorry i got a bit confused[&:]
thanks for your help
