Exhaust rattle.

The new Boxster is excellent, however, I have a catalyitc converter rattle on the right side, It is alot louder when the car is cold. Any suggestions for a solution?

Maybe i will just redo the whole exhaust system like this haha.

Knock it with a rubber mallet when it's cold if something rattles on the inside you have to replace it. If it's one of the rear cats make sure its not just a loose heat shield.

Yeah I originally assumed heat shield myself, but yeah I sadly found thr it was inside the cars, no alternative solutions?
