Hey all, I just noticed I stil lhvae what appears to be a ground wire or something similar (braided stainless, it looks like) hanging off my now removed CAT...
I looked underneat the car and the test pipe has a hook up for this, but how crucial is this "wire" ?

it was bolted on to the exhaust pipe and looks kinda like the ground strap in the engine bay? i was under the impression that that strap grounds the 02 sensor and is NEEDED for proper gas consumption and etc.
