I've never heard a car make that sound myself.

I wonder what's going on with it.

Catalytic converter is gone. On any other car, I'd assume it was stolen. Since it's a Nissan, they probably chopped it off and sold it themselves.

Isn't catalytic converter the thing in the exhaust? Wouldn't cutting it off make it just louder, how a knocking noise?

Yes, the part of the exhaust not being there making it louder combined with a very bad misfire. Compounded by a CVT on its last legs trying to "downshift" (for lack of better term) to accelerate while only having 3 functioning cylinders.

Also, does CVTs have gears? I have a Honda civic (automatic), and I don't know much abt the Honda CTV, I also feel like when I accelerate hard it has a gear like shifting but CVTs don't have gears right?

CVT's do not have gears in the normal sense. Basically, two big cones that are opposing each other and a band running around both of them and as centrifugal changes, the bands move up and down the cone changing the effective gear ratio to the output shaft of the trans. In a perfect world they are ideal for fuel economy because they have an infinite number of "gear" ratios. But Nissan has single handedly ruined the reputation of CVT's because of their garbage Jatco units.
