1991 F150 Exhaust

Hi everybody. I have a 1991 F150 with about 190,000 miles. I hit a turn pretty sharply yesterday and the exhaust pipe broke off or came unfastened from the cat (i believe). I don't really mind the noise because it is just a work truck, but I don't want to get pulled over. I have heard there are some cheap little mufflers that I could pretty easily clamp on, or maybe I should just try to reattach the pipe that came off? I've never worked with exhaust before but it doesn't look so hard. Any help is appreciated!

i would reattach the pipe due to the downstream oxygen sensor.
