If its only 1 to 2 weeks till you can get some muffs i say dont waste your time on the repair now. Just turn up the tunes for now. As for muffs the XS borlas would be nice but are pricey. If you want to source them locally on the cheap maybe try the thrush turbo or dynomax turbo mufflers youll need the outlet to be 2" cause the stock diameter exhaust pipe back there is 1 7/8"
