After I seafoamed of course.

 

I dont think the can said to do that with the tail pipe

 

I was at a traffic light behind another MCS the other day and of course he wanted to impress me so gunned it pretty good when the light turned green... Not very impressed, his car was smoking like a diesel. All this dark smoke poured out the tail pipes, just enough for me to see it but not enough for the driver to notice... Wonder what his problem was?
