Unknown Bolt

Noticed this bolt in my parking spot under my truck. Currently looking for a possible source for the bolt on my truck but figured TW may have a quick answer given it is pretty unique.

Any ideas on where this belongs? I have had some chatter lately on my belt.

 

Looks like the bolt where the cat back bolts to the Y-pipe at on the exhaust

 

Someone lost a bolt from exhaust system. Doesn't look like a Toyota bolt, though.

 

Also vote exhaust bolt.

 

it goes to the flux capacitor

 

Its a coilover bolt

In that it looks like a tiny coilover

 

2015 TRD Sport it matches the exhaust bolt here exactly but I’m not missing any. Any idea if this is the only location?

 

Someone tried removing your exhaust or catalytic?

 

My Subaru has exhaust coupler bolts at the ball joint exactly like that, so probably from someone's exhaust.

 

That would be awfully nice of them to unbolt it, usually they just take a sawzall to get it off quick.

 

Everyone is wrong. It’s a strut from an RC build.

 

Maybe it fell off someone else's car??

Look on the driver's side where the Y-pipe bolts to the cat on the driver's side

 

True. A 1/2 inch Milwaukee electric impact and 5 seconds and you’re done.

 

This. Someone was trying to unbolt your catalytic converter. Check you truck again on both sides.

 

Thanks for the responses. Only the passenger side has a spherical joint on the exhaust pipe. Driver’s side is all flanges from what I can see. I’m going to assume it is from someone else’s car.
