Try to get the car in the air. If you have a fixed system (welded) you may have to modify to fit.
It sounds to me as if your sytem needs to be properly examined for fit then adjusted. Your mufflers system should not be riding on glass.
As the other tread read, get it checked and fixed. Bad news to make contact with glass.
A muffer shop with proper lift equiment can at least look at it and probably fix it.
