This is the header im looking at, the owner doesnt know the brand but it came off a 1984 633csi, do they look familiar to anyone?
m30 e30 header question
Moderator: martauto
Can or has anyone measured how much room you have for the exhaust header with a m30 when put in a e30?

Im using the e30.de ones and mostly likely engine position 3 or maybe 2.5
i'm not too sure on this.
there's surprisingly little room between exhaust manifold and chassis rail on an e28 and i'd guess an e24 is similar. remember on a RHD car there's a whacking great steering box in the way
having owned an m535i and a 335i at the same time i'd say working on the exhaust mani is def easier in the '3.
i had a set of alpina B10 equal length manifolds from an e34/32 which *might* have fitted if the steering shaft hadn't been so terminally in the way lol
those headers are more compact than the ones i have. they might clear the chassis rail, but as for the e30.de mounts... you'll have to trial fit them...

I doubt that would fit but it certainly looks very nice.
