Are E36 exhaust manifolds prone to breaking

[jetpacman]

I have been told that the exhaust manifolds all have a weakness where they break right by the flange that bolts onto the engine. Is this true for all the different engines, or is it only for certain engines.

I have a 318i with an M42 motor and my manifold broke. When I bought the car a couple of years ago I noticed a hissing sound and had the manifold repaired after it completely broke off and the car started to sound like a Beetle. I have noticed the hissing sound again now only a week after having it repaired and I fear that it has broken again. Possibly poor workmanship, I hope not though. It goes "sssssssssss" when I put my foot down.

This is the first time I hear about an E36 exhaust manifold breaking

Perhaps its limited to my region...

those exhaust manifolds are cast iron mo-fo's, i highly highly doubt that its cracked, maybe its around the downpipe.

The exhaust manifold on my E36 M3 cracked just above the flange where it attached to the exhaust pipe. No cracks where it attached to the engine, though.

OBD 2 manifolds are different on I-6 e36's at least
