just grounded my car as i was doing a 3point turn in the road i purposly went a bit on some grass to save doing as many turns, but the grass was slightly downhill so it grounded out quite hard,i managed to drive it off the dip but now i get vibrations all through the car and as the revs get higher they worsen, is there any ideas of what iv done? i cant see any holes in the exhaust?
please help me
