Someone enlighten me, does white smoke always come out of the muffler during cold driving, like constantly, mine is only is noticeable when taking off from a stop sign and you can see the smoke from behind you for 2 seconds, after that it's not noticeable at all. On idle there is small amount of smoke, it's a very light transparent smoke, On take off it's a bit more and you can see it by the headlights of the car behind you.

P.s-I just installed mandrel bent 2 1/4 exhaust.
-Changed headgasket 2 months ago/ oem honda.
- No oil in coolant or vice versa.

 

As a result of the catalyst process, water is created in the exhaust system. Obviously the exhaust is hot, and thus the water is vapor. During cold driving this vabor is seen as steam out the exhaust pipe. Consider is a sign of sufficient catalyst efficiency.

 

I guess i was just a little worried for nothing
