I don't want to get in match against who knows what ect.
My mechanic is one of the finest porsche mechanics in the United States. He has informed me that there is indeed a difference in the early 3.3 exhaust system vs the later cars. In fact it's the manner in which it handles the turbo gas exhaust through the exhaust system. Besides the fact this is a RoW exhaust not a U.S. spec exhaust.
