Question: TRD Header bung o2 sensor

Looking down the y-pipe of my TRD headers.. would you guys say that the o2 sensor not being fully pushed in would cause misreadings and performance issues?


Quick back story: snapped the original bolt several years ago, couldn't get the broken piece out. Quick fix from a local exhaust shop was to weld a bung over the original so now I'm looking to get it fixed proper

This is the result..

 

If you are not having any issues I would leave it, you could always have a new installed clocked on the other side of tube and block original one.

 

If your not having problems it works fine.

If the truck has been sitting not running and your not sure .

I would go with a new pipe and be done.
