Hello, I 'm writing this in Englisch because in Deutsch it is making to much time for me
But I found out that my Mittelschalldämpfer is leaking. So I went to the Stainless steel exhaust manufacturer and he is saying only the Endschalldämpfer and the cats are made from stainless steel...
I thought the whole exhaust was made from stainless steel?
Now I get a new custom made stainless steel MSD with the connection pipes to the cats and ESD. He is making it for about 350-375euro.
We measured that the diameter was about 55mm each pipe, and we are thinking to replace it with 63,5mm... would that be a problem for the engine performance?
