Been searching for an exhaust for my UrS4 on and off for ages now. Struggling to find anything that's not very expensive or in another country.
Came across this cheap
SS B5 dual pipe system:

Looks vaguely similar when comparing the undersides of both chassis and the pipe layout.
I doubt anyone has ever tried, but any experience on weather this system could be made to fit without too much work, or if it's not worth going down that road at all.
