No one, no one dares doing it here. It's ridiculous! From normal garage to exhaust specialists.
There is a guy in Hamburg, Germany, who I could hook you up with, if interested.
Shipping will be more than inside Germany but I reckon not much.
I had it done by him, great work, good price (~350€ if I remember correctly) and I am absolutely happy. And you can even chose how much louder you want to have the exhaust to be.
