Front subframe damage and weird bolt in undercarriage?

[MartinNoHo]

Curious if other 18+ S550 owners have this dent in the front subframe or if it was caused by something else is it that serious? In my opinion, it doesn't look serious at all. In addition, I found this really long bolt by the driver side (not present on passenger side) that is the cause of a metallic scraping sound on very steep inclines and declines (my car is 1.5 inches lowered all corners), does anyone else have this bolt only on one side. I'm a picky person who overthinks, and I bought this car used. Any thoughts would be helpful thanks! pardon the picture quality.

The long bolt i'm not sure what that is but i'm leaning towards it being the exhaust clamp. The subframe you can see a witness mark above that dent. I'd say someone ran over something on the road. Unless your car drives weird or can't be aligned properly I wouldn't worry about it.

In that case take a metal cut off wheel and zing that sucker off. No more bolt. It's not even a half beer job.
