Default GMMG on, now vibrations, help

so I have the GMMG on for a week now, I get a loud buzzing sound from the rear of the car; it only does it when the car is sitting and idling ,
is it a bad hanger, or something that <i should tigh, it sounds like a body panel buzzing , kind of the same when people have loud subs banging the car
help help help , its annoying

Check the pipe that goes over the axel. I had to put a spacer on the passenger's side hangar to raise that side up.
I have also heard that some people get rattles from the heat shilding, so you may have to bend that a bit.

Hmm, I put the GMMG on an otherwise stock exhaust. Didn't have any problems whatsoever. I'd check the heatshields as suggested above. Good luck!
