i have an 03 to and it dumps white smoke like a wazoo at idle and every stop sign there is like a small cloud so thats what it is the injectors?

does it matter if its straight piped? will the dealer not like the straight pipe?

Was the truck originally equiped with a Cat? If so, put that on as they could deny you on that.... But doubtful.

If not Cat, you're fine. I was...

yea take it in they shouldnt mind about the strait pipe that has nothing to do with injectors

If my truck does not produce any smoke out the tailpipe but still smells like deisel and the oil smells like deisel could that be something else or is the smoke to come ???
