I ran off the road a couple weeks ago pulling out of a driveway and my back tire hit a dip and knocked my exhaust loose where it slips in. Other than sounding like a v8 with straights it was not an issue. A few days later it started to run rough.I fixed the exhaust but it continued to get worse. Loss of power in and out. Now I crank it up with a rough idle and continuous loss of power. Check engine light is not on so I do not know what it could be. And now it is making a weird noise I cannot really locate.

Check along the exhaust for loose wiring for the O2 sensors, It is possible the harness pulled free and the wire insulation is getting melted. I would also get is scanned with a dealer level tool to make sure there are no hidden codes (not all codes turn on the light).
The noise could be just about anything. Try to determine when it is the worst? Cold start? When fully warmed up? While in gear? While idling? Does it have to be moving?
Maybe shoot a video of it when you can hear the noise and give us a link?
