Just finished installing my M&M Headers tonight (along with straight pipes again and she sounds like she should), fired the Viper up and noticed some smoke coming from under the hood. Obviously shut the car off, popped the hood, saw nothing.

Take 2: Same story after about 2 minutes at idle. Noticed the smoke source coming from both upstream O2 Sensors (or maybe some residual whatever from the weld burning off?)

Anybody else have this experience with new headers? Or have a theory on what's up?
Thanks!

Any new exhaust stuff will have oil and grease on them that need to burn off. If its coming from the O2 bungs, they may be loose indicating an air leak.

Yup, a little bit more this morning. No more since, has to be residual oil

Carry on
