Everyone knows when its cold outside you have that smoke from the exhaust because of the warm air,.. I have noticed when its like 40 degrees outside everybody around me has a little white fog coming out of the tail pipe at a red light , but mine looks like a fog machine ( I have the 2003 fx4 (5.4 ) I also always notice in the morning I have a little water right at the end of my tailpipe always.. i know its not a head gasket this has been checked.. Local mechanic says its condensation... But its always there.. So the other day i am driving along and decide to punch down on the gas pedal and I noticed a little smoke just for a second... .. I guess i am just paranoid.. I really like to catch problems early before they get serious..

 

Stock or aftermarket exhaust?

Where you are, and, how much do you drive per week, will contribute as well.

Condensation is normal, and, not much you can do to prevent it. Your muffler may be attached at a slight angle to be trapping more condensation than others may be.

I wouldn't worry about it. Drive on.

 

There's nothing wrong with your truck. It's normal.
