i damaged my ypipe on a speed bump and took it off until i can order another one. will it be ok to run for about 3 days with just catalytic converters on it, the y pipe off, and the collector pipe just tied up? is there anything i can damage in my engine not running it through a muffler or andthing i can damage on the car? thanks guys

the only problem I see is ur 02 sensors, they might tell ur computer that the car needs to run rich. don't go off my info tho, I'm really not for sure. just trying to help u out.

I've been running no muffler for about 4 months now, no problems - other than sore ear drums

No, you'll be fine - especially if the cats are still on.
