Whenever I rev my engine there is a sudden shaking feeling around 2,000 RPMS, the wheel starts to shake too and not only that whenever I rev the engine, out in the back rattles like no tomorrow!

Here is a video I did,

First I rev it slowly to about 2500 RPM then I take it to around 5500 one time near the end. Something is rattling very badly and I am hoping someone will know what I can do to fix this. Also, can anybody inform me what kind of exhaust this is? It sounds kinda loud to be stock. Thanks in advance!

 

Either something is loose/lodged in your heatshield or your cat has something broken off in there.
