Loud Engine on 2007 Pontiac G5

I am the second owner of a car that was in a front end collistion. The car is loud. It actually sounds like the RPM's are really high but, they are not. The noise "speeds up" with the aceleration of the car.

Sounds like a damaged exhaust manifold, exhaust pipe or muffler system.
