hey guys i have a bit of a weird problem. my exhaust is rattling to all crap, it sounds to be at the muffler end. to me i thought just a bracket is gone. but the weird thing is outside the car you cant hear it, inside it is as loud as. i have to turn the stereo up even louder to drown it out. what is ultimately the most confusing, is that at idle, and with the handbrake on it is pretty much quiet, but when sitting at the lights or something with my foot on the brake it rattles like it is going to rip itself away from my car. Any thoughts?
