Yeah, I'd say it sounds more like crap from the road. Especially likely on a hatch since the airflow off those is all jacked up, as I put it, and so more chance of dirt/grime ending up on the back.
If you don't smell anything funky outside the car when it's running and at WOT you don't see any black smoke than I wouldn't worry about it... just my 2 pennies.
