Can anyone help or have any ideas???

996 Turbo with left hand exhaust rattle. It sounds like a pennie is trapped or something linked to engine revs as increases when more rpm is added.

Very tinny type of sound, link an automatic gearbox being put into park while still moving slightly?

Many thanks as usual.

I am guessing a 996 Turbo exhaust might be quite a bit different to my measly little 986 2.5 system, however I had a similar issue when I bought mine. For me it turned out to be a heat shield that was mounted to one of the CAT's. One of the mounting clips had all but perished. Replaced mine with one I had from my old BMW which was identical, so they may be pretty common. If you can get under the back of the car with it lifted (Jacked up safely of course!) then have a look, try and rattle any heat shields on or around the system about. May be a few quid and a simple fix.

Could this be the baffle inside the box? That's not uncommon either = New box or get it opened up and re-welded

Sounds like it's coming from the turbo.
