Hey Jeff,
Thank you very much for your message.
I've heard that people drill something in the exhaust system but I'm not sure what and where I should drill. If you have some info regarding this question PLEASE LET ME KNOW ABOUT IT.
Thanks a lot

PS: Yes, my car equipped with the catalytic converter

Best regards

: I think the fact that it only occurs when the temp is low is indicative of condensation in the exhaust. As your car cools the water vapor in the exhaust and it condenses back to water. This water sits in your exhaust until you start the car again. AS the water heats it turns to steam and appears as white smoke. THis is not damaging to your engine but may lead to premature failure of your exhaust or catalytic converter (if so equipped). Some people have tried drilling holes in the pipes to allow a drainage path for hte condensation.
: This is one theory
