On cold mornings it is pretty normal. It's the accumulated moisture evaporating out of the exhaust system as the system warms.
If you are concerned that it Amy be your head gasket leaking, smell the steam when you start it up. If you do not smell antifreeze, you're good to go.
Cars do indeed produce exhaust, but they are not the only source of exhaust which can come form other forms of transport, house boilers and factories.
You're burning oil.
The two combine to produce smoke.
If the engine has just been started up then it may be condensation caused from the exhaust pipes warming up and should disappear once the engine has been operated for about 20 to 30 minutes . ----------------- Engines produce water vapor as a by-product of combustion. The water vapor condenses in the exhaust system and drips out. I see drip holes on many mufflers also.
I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.
Sunlight, normally in the morning
15 minutes.
Using a cat back exhaust system can benefit you because it will free up your exhaust gas flow and produce a more pronounced engine note. Installing a cat back exhaust system will also increase your fuel economy.
A vessel would produce the highest concentration of Carbon Monoxide near the engine and exhaust outlets.
A Specialist Dealership is where you will find one brand of car (as per any Main Dealership) but will primarily only work on a version of that make. For example Honda make many different models but they also produce 'hybrid' (Electric & fuel) powered vehicles; a 'Specialist Dealership' would primarily only work on the 'Hybrid' vehicles where the 'Main Dealership' would work on all the normal type vehicles but not the 'Hybrid' vehicles.
You could get a "turbo" exhaust system or "glass packs". An ovrsized exhaust (3 inch) can produce a slightly different, deeper sound.
The engine will produce more exhaust.
