I have been getting a vibration/rattle coming from the rear of my MY05 997S. It happens on startup and at low RPM (under about 2500 RPM or so) and goes away after that. At first I thought it was maybe some kind of heat shield on the exhaust that was maybe loose but had no idea if there was even a heat shield to come loose. I have PSE and have had it unplugged so it's always on (loud) and last weekend I plugged it back in but didn't ahve a chance to drive it until now and when I did, I noticed the vibration/rattle wasn't quite as loud as it was when the thing was unplugged but it was still there at low RPM... Has this happened to anyone else? Does anyone know what it could be, (obviously without hearing it)?

 

Something is up with your PSE. You shouldn't have any vibration! I replaced the stock exhaust on my 987 Boxster three times in the listed order.

AWE = vibration
Speedart = vibration
PSE = No vibration at all unplugged.

Hope you find out what is going on but vibration in an OEM PSE is not normal.
