Well you should certainly see your doctor for that condition. :rolleyes:

As for the mufller I presume (side of engine)? Or perhaps catalytic converter (rear or car/front of engine)... yes they are known to eventually "go bad" or just "go bad" on their own. In order to diagnose the rattle you can remove one of them and shake it around in your hands... if you hear the same ratlle.

But I think more commonly it is probably just a lose bolt. If you do poke around near them and do any sort of bolt tightening be sure to have let the exhaust cool down sufficiently first.

Might be the PSE valve is broken and loose.

Does your PSE still function correctly (ie. quiet & loud)?

Yes when I switch PSE to quiet mode, the rattle goes away. Is the valve replaceable or is a new tail box required?

Thanks

I don't think the internal' valve can easily be replaced. You'd have to open up the muffler to do that. I suspect you'll need to replace the muffler and I'll bet Porsche wants a small fortune for it.

If you can't live w/ it you just might be better off replacing the mufflers (right & left) w/ some good (non-PSE) aftermarket setup.
