Series 5 Turbo II Exhaust to downpipe flange
Hey all - I’ve searched high and low for a part that I just can’t seem to find. It’s a flange that attaches the downpipe to the turbo and I have an exhaust leak there. I’ve found plenty of different kinds but they don’t really match the shape of mine. I’ve attached some pictures for more clarity. I’d appreciate any help.

The turbo backing plate.
This piece was never available separately from the turbo.
I have made a stainless backing plate so I could weld an external wastegate to it.
the stock cast iron chunk is going to be the most warp resistant material.
If it really did get warped somehow, it could be surface ground.
I have made/used multi layer metal gaskets between the turbo and backing plate.
Make sure its not an under tensioned WG flapper that is tinking with exhaust pulses or the WG flapper pivot leaking when cold.
If the car is on a lift a cold start with water vapor leaking will show you whete the leak is.
Make your exhaust louder do you dont notice tiny exhaust leaks?

Just lifted up the carpet and found the hole. Thanks for the tip! Can’t wait to be able to drive this thing again. I’ve inhaled so much gasoline my hearts started to go dorito shaped.
