Dual Exhaust?
Hi guys newbie here. Question regarding the exhaust. Just got my C300 2 weeks ago and usually if it’s cold in the mornings I will warm up my car before going to work and I noticed that the exhaust smoke/vapor comes out Mostly from the passenger side exhaust. Not that the drivers side exhaust is non functional but looks like it has only about ~10% of the exhaust coming out. Has anyone else noticed this on their car? Thanks in advance for the help!

Dual exhaust
Dual exhausts are generally used on V configuration engines, with two cylinder banks. The C300 is a straight 4 cylinder so the Y and the split are just because dual exhausts look cooler, and are more symetrical looking.

I noticed this today. Steam from one and nothing from the other. I put my hand over the one without steam and could feel exhaust gases but looks like it’s fake when only one puts steam out.

Attempting to ignore the fact that this picture is the saloon, I won’t be changing an exhaust to make steam more even.. in fact as soon as the equity is level, mine will be going back and I will never go back to MB until such a time as MB up their quality game.

Just one of those small things that will drive me insane. Absolutely love the car, but between this, the sputtering wiper and the cabin noice I’m starting to go nuts. Then again I prob have OCD but I think these things should be taken care of early in life cycle of a model.
