2: UK

Scroll down to exhaust section for all the part numbers to compare, there isn't a Swiss link, only German, but I chose Uk as its english.
Hope this helps as both parts numbers are listed with the same number I think they are identical!



If there are any differences in the cars to allow for differing legal requirements (exhaust gas emissions) then they would most likely be in the catalytic converter spec or engine control software.
I think your safest course of action would be to check with Swiss authorities responsible for "approving" your car for road use, and ask them for their specific criteria and requirements. Get it in writing, preferably.
