Connector hose for Rossier Engineering Exhaust

[Sdahlheimer]

I cannot locate a source for the connection hose for the Rossier Exhaust system. I called Rossier and the new owner and has no idea or source. Does anyone have suggestions?
it is for a 2001 GTS.

Google turbo hose coupling. Measure the pipe as find the closest size. I think you'd like a 4 ply hose.
