It sounds like most of the exhaust is missing and it is running on one rotor.

A little background on the problem?

does that mean a blown rotor? for the exhaust system should i replace, bc yesterday the cat caught fire

also when i drive the power is still kicks its just when i go to a stop the engine starts to do what it did in the video

My moneys on blown rotor, or atleast ones about to go , its running rich, cant combust all the fuel, thats why its spitting fire.( well rotaries sometimes do that anyway but...LOL) .
can you do a compression test ?

ima do a compression check tomorrow. the reason i dont think its a blown rotor is bc it drives like normal. theres no lost of power. its just when i stop the exhaust shakes alot which makes the engine shake.... is there a possible that i need a new exhaust system since it seems the airs not flowing threw correctly?

I suppose that could be it, I gueess...luckily for you both of those two are easy to check......

When did this problem start? Can you describe what happened exactly?

this happend thursday night. the car was driving perfect as always and when going to chill with my friends at night the catalytic converter caught fire. once this happened thats when the engine started the shake when stopped and also bog like it was going to shut off.

so the rotor is not blown. did a compression check and both passed.... so if its not that what could it beee =[

could a bad motor mount cause that shaking of the motor and rattling/chattering sound?

Sounds like a bad fuel injector or an ignition issue.

Ooo I will Check the mounts.:O
