Ratta-tat-tat Sound on Startup and While Shifting

Everything in my car is stock OEM. I've had a rattling sound on startup and when I engage the clutch during shifts between 3rd and 4th gear since I got the car. I'm almost positive it's the tailpipe hitting some part of the undercarriage. It's not loud and it doesn't do it all the time.

Not sure if there's a loose exhaust hanger or if this is a design flaw. If it's the latter, I'd guess others would be experiencing the same thing.
