DDK - Die Deutschen Klassiker

Managed to fire up my 912 recently. Have a blow in the exhaust muffler. Where the manifold pipe enters the can. Not sure if it’s twin walled there. Might have a go at welding.
If that fails, anyone have a good one for sale or can recommend the best type/place to get one?
Cheers

Is a Euro exhaust, with the heat exchangers, or the J pipe one, as there are two different back boxes dependant on the heating system.

Euro. It has heat exchangers.

Best deal I could find on a new one was a Dansk, fit is OK, needs a bit of juggling but lined up (almost)

Thanks. Ordered
