Can you identify what this is under car? (pic)
I was looking under my car the other day and I saw this rope-like thing hanging down. The picture was taken on the drivers side of the car facing the front of the car. The rope is attached to a bolt. I'm just trying to figure out why it was just hanging there not attached to anything. I didn't see any wires running through it. It sort of feels like a thick shoelace. Does anyone know what this is?

This strap helps ground the exhaust and in turn your O2 sensors.
Of course the exhaust manifolds bolt to your heads/block which is grounded but the gaskets used throughout the exhaust system prevent a good consistent grounding point. You can imagine that proper O2 feedback is important for the ecu therefore this grounding strap is necessary.
Don't throw it away as someone else stated.

The manufacturer felt that this grounding strap was important or they wouldn't have installed it in the first place. The length of this strap may have allowed excess slack which would allow it to get hung up on things below the car and get torn, as many have mentioned. You may not notice immediate problems, but as someone stated it could trigger a CEL, and potentially fail at inspection time. This particular strap on our cars connects to one of the ~17mm cat bolts.
It seems that some people, stardust, have no clue as to what is going on under an automobile. The majority of automobiles built today, use mulitple cats/O2s, and indeed have some form of grounding strap connected to the exhaust.

Mine as well as a few others I know for sure have removed theirs when it's come loose and have not had any adverse affects from doing so. It's been over 2 years for me, no codes. It's not that crucial.

With all the talk over the past year or two about grounding kits and what not, why wouldn't this be any different? If anything, I'd consider replacing the braded grounding strap with a thicker gauge, not removing it.
Grant it no one has seen any ill-effects from removing it, but why not take advantage of the grounding possibilities here.
Not to mention, it would increase good grounding to the O2 sensors as stated in previous threads.

Considering there are no O2 sensors anywhere near there on any Cali spec car like more than half of 00's, almost ALL 01's and all 02-03's... It is useless.
If you have a Fed Spec... It might be usefull, although very unlikely.

Both ends look identical
