Well, 2 located in Switzerland:
http://www.daehler.com/
http://homepage.hispeed.ch/R-S-K-Tech/ - they provide great quality AND pricing.
Basicly every good exhaust shop should be able to do this, just make sure they use good metallic catalysts.
However, the modification will be detected and so there is no reason to perform this kind of DP upgrade. There are better solutions around, even catted, which would be my choice.
