Get the cable ties out and use them to adjust the position it sit in. Don't put them on the exhaust tho haha. Wrap them round the rubbers and you can put some rubber hose inside the rubber hangers to stiffen them up. That's what I done on my GT. but when it was wet it still banged a little. It bugged me so much once, I stopped the car in the rain and crawled under it to put some more ties on lol if you don't want too use cable ties you will need to get it tweaked with some gas
