I have a metallic rattle noise that only happens in certain RPMs when the engine is warmed up, coming from one side of the engine (passenger side), it sounds like up near the engine somewhere. It sounds just like a rattling heat shield but I've checked the obvious heat shields and for exhaust component contacts with frame, etc, and so far can't locate the source of the rattling noise.
I have no check engine light problem nor performance problems (at least that I've been able to notice - car has been like this for about a bit over the year since I've bought it, and it's my first boxster.) 2001 base 2.7. Thanks!

Surprisingly, in my case I did not hear any rattle from my faulty CAT.
I have read that the rattling could be due to the need of a new engine mount rubber as the play in a worn one seems to cause pipe rattles as the engine moves around excessively.
