ok this might be dumb but ill ask anyway.. when i jump on it and bang second gear if i get wheel hop i get this banging.. i only hear it from 1st to second if i hit the gear really hard and wheel hop.. if i go over bumps i dont hear anything.. if i bang everyother gear no noise.. i cant tell where its coming from.. my buddy said it might be the rear seats moving up and down or the shocks compressing up and down... any info would help oh its an 04 gt just so u guys know lol i did notice today that my tailpipe is very very close to my trunk underneath the car.. like a half inch away, that might be the sound i hear if the car hops that probably would be enough to make it hit the bottem of the trunk, but it does sound like everything is shakeing and its fugged up..
