I understand that when u first start ur car in a cold weather there be alot of smoke coming out of the exhaust, but as the engine warm up as u drive the smoke some wat would come out less. On my I noticed that it about the same when I start the car and after drive it for awhile. Just want to see wat ur guy opion on this and to see if anyone noticing that with their car too.

What you see is water vapor. Perfectly normal. Car exhaust is 15% water.

Even if your engine is hot, the exhaust pipe (after the cat) isn't and water starts to condensate.
