split exhaust manifold

good price

�279 to remove the manifold, weld it, replace and an oil service. didn't think that was too bad really

vrrroom vrrroommmm! chug chug vrrroom vrrroommm!

If we aren't supposed to eat animals, why are they made of meat?

just had a tlephone call from the garage. job dome!

the manifold has come of without hitch has been welded at branch 4. picking up at 6, still don't know the cost!

i've been to sacerd to find out the cost of new one. hope they can weld her up!

I think it's all stainless, but the different thinknesses and possibly grades of ss cause a huge difference in expansion coefficients.

Mike's looks pretty bad, mine was only cracked. I think a properly repaired manifold should last a long time making the repair very cost effective.

Its is nearly 100% but there is mild steel in the sandwich plates at each end.Thats where its cracked/broken off in the picture that was posted.

intresting remarks made by you both ...thanks for the answers ..there is one thing if i had hold of either in the pic i could tell .what part was S/S or M/S ..it hard to tell by the pics old and new

m/s in the sandwitch plate could errode the s/s in time and hence the fatiugue compounded with the heat would almost cause this common problem ..

but looking at the new pic ...the welds on them are two diffrent shades ..meaning one was done with a stainless welding system ..and the other with a mild steel system ..and i doubt that the metal is a composite of mild and stainless .. if that was the case it would be a "dismilar" steel or a mixture of both at there joining points .....so one would contract and expand at diffrent rates ...did bmw have a crazy day or was there method in there madness?? it has to be one or the other .cos it beats me why 2 contrasting steels should be met at such a heat sensitve point ....

just out of intrest [and to stop boring myself here. ]

how much is a new one ?????

what happens if the bolts holding the manifold on shear? would they have to be drilled out?

The manifold is a mixture of stainless and mild steel and most people reckon thats why they are prone to cracking.

mike thanks for the picky you allway come up trumps ..

do i take it the old in the pic is actually a mild steel one ??? it does look it ...are some stainless others mild steel?
