I've dedicated a few hours to slowly getting the heatless headers and muffler in place over the past week, having to wait for a new stud for few days. But the last piece is the o2 sensor. If I pull the grommet out of the tinware the sensor makes its way to the o2 bung on the header, but then that hole where the grommet was will be open and almost the entire length of the wire will be taut and outside.

Whats the solution? I was thinking of using a hole saw attachment and making a small hole by the plug wires and just dropping it out that way so its not entirely outside.

 

I would make a new hole, and just plug the old one.
