ok , my friend was behind me while i was driving and he said when i left first gear he saw some smoke, he wasnt sure what color it was but now im thinking its either because i have test pipes or because i had nitrous on my car. i went home and reved it and saw a little bit of black smoke. is this normal. The car drives like a champ. Also do are cars run more rich or lean stock
thanks

 

I think its due to no cats.

 

the car should run rich from the factory, but the big thing is check your oil level and keep track of it for a while. Sometimes you can get some burnoff but the oil level will tell the tale.

 

ook thanks guys
