Since I put my exhaust on, I noticed upon start up that I get some white smoke when the truck is cold. Seems to go away when the motor warms up. Checked my balance rates and they are well within spec. Where else could this come from?
Normal cold issue that seems to be magnified by the more open exhaust. Most everybody notices it when it gets below about 20*. I really notice it around zero with the high idle kicked in.
