GMC "Denali" (actual model is a secret!) Catalytic Converter Rattle
There was a small rattle in driver side Cat so I replaced it. Now the new rattle is MUCH WORSE and VERY loud (I'll link a video). The car also recently started to lose power when driving up hill, I was flooring it and the RPMS went up a little and then started dropping as I was flooring it. The car only went about 10mph as the temp rapidly increased. What could be the reason for the rattle getting louder and the loss of power and are they related. Thanks for any help you guys can give!

what sort of help you need seems like you caught whats wrong already?
the one you replaced was an used cat? and yes considering how much it rattles it must affect the car's performance..
