997 with PSE. Exhaust seems to rattles at idle when hot ....

[MadMark911]

... but is quiet when it's cold! Are the exhaust valves on the way out? Anyone had problems with them sticking?

Looks like it will be one of weldings inside the exhaust that broke causing a pipe and/or plate to come loose.
Replacing a PSE exhaust is expensive.
Best is to look for a shop that can open and repair this.

Thanks M030 - I'm going to get it looked at, but any idea on the replacement costs of each box(just in case)?

It could be one of the valves themself. Does it rattle when switched on and off?

could be the cats, mine had both changed due to them rattling at idle!

All useful thoughts! In normal mode it's quiet - just rattles when in sport mode! Sounds like it could be the valves themselves (which were sticking closed a couple of weeks ago)!

Sounds like your answer. And the remedy is to use it more often so they don't stick

you can rule out the cats then as mine rattled in either mode.. which you'll be pleased about as they cost £2500 plus fitting from an OPC

Sheet! Even better - when you "pull the (orange) plug" in the engine bay - they don't rattle at all .......

Problem solved - the exhaust tips were loose and on one side the retaining bolt had snapped (or been snapped by somebody)! Now fixed by Nine Excellence on Wednesday (as I noticed one was at a jaunty angle).

No finger pointing, but it spent some serious time with a car detailer a couple of weeks ago .....
