I suspect it is a broken demon bolt from when I had a shop remove the OEM cats. Odd thing, I tried to fish it out with my magnet and it isn't magnetic. It believe it is 10mm. Any idea where this may have come from if it wasn't a demon bolt? If so, it's been hiding in the engine bay for a few months. Car feels fine, no shimmy, vibration or pull. I guess hitting the pot hole shock it loose from where it was hiding?
