Sonata NF (2006-10) :: Engine Sound Much Louder Like Revving / Humming

In my 2007 Sonata, I hit a poorly placed high manhole cover in a dip in the road, in the dark, going 30MPH, whacked it good before I could adjust...

I then pulled the car over, it seemed to go dead, then the car did crank back up, the engine sounded much louder, like a loud rev/hum, not quiet like usual.

I next drove a mile to a c-store, transmission seemed OK, no leaks, did see a check engine light briefly, but it disappeared. Car cranked OK, headed home, same sound right at cranking and at moderate speed.

Finally, I jacked the car up on the front left, from research appears that the plastic engine shields got smacked good along the front and near the right tire and bent back quite a bit on the left side. There seems to be no other structural damage that my untrained eye could see, just one indention you'll see in a couple of the photos that I think is part of the car design at that spot.

Again, no leaks, no smoke, no caution lights of any kind now.

Photos are attached...

My Hyundai's engine now sounds like a Mustang! Hoping it's just the engine noise from these plastic covers now being bent/destroyed in some spots, exposing the engine and the typical noise you'd hear without them...
