Why is my car smoking?

I think it’s fun! As you progress, there are different types of “exhaust”: music notes, fox tails, peace signs, flowers, etc. To remove it click on the paintbrush on the left side. You’ll see a gym all ma home. There are tabs above that.. click on the middle tab, which looks like an upside down, dynamic teardrop, and on Tbilisi next page, you can choose your exhaust type, including no exhaust at all.

They give you a choice if you want it or not , but how to get rid of it I don’t know it’s sooo annoying
