Well, some friend's wouldn't shut up to rev my engine, so i did, hit redline and i heard what sounded like it backfired (i do have a small exhaust leak) then i noticed quite a bit of white smoke or what appeared to be that color come out my exhaust.

 

Are you sure it didnt have a tint of blue to it? When these backfire there is a lot of smoke that pours out of the exhaust!

 

That's why i said i'm pretty sure it was white, i'm not completely sure, but my car has never smoked any color at all before.

 

Trust me, its from the backfire!

 

Well, good.
