I thought I saw something from EAS at least promoting their downpipes, but not sure anyone went ahead with the install yet.
Some tuners in Europe have them installed but I am not sure anyone has posted specifics here (yet).
A local turner here is also working on exhaust/downpipes but I haven't checked with them for a while, might be time to sync up again
As for work my guess is it's not trivial / quick as you might also need some special tools for the turbos to (re)align given the location of the downpipes inside the "V" .
If I find some time this week I might have a look at the F10 shop instructions to see what they say (labor estimate, tools etc)
