Got rear ended 03 c320
 

Hey guys I was waiting at a red light when suddenly I got rear ended. I felt my car move forward slightly. There was no damage to the body or the bumper but ever since that happened my steering wheel has started to vibrate slightly enough for me to notice and every time I accelerate I also hear a whistling noise. There is definitely something off internally. Please help me find out the potential problems and the severity of said problems before I go and get it checked out by a mechanic.

Possible kink to the tail pipe/exhaust system. Just a guess from the whistle noise description. Or some of the air intake tubing under hood for the same reason along with rough idle. Just a guess.
