I think my o2 sensor is welded out
I took a look under my car yesterday and noticed something weird. The cat has a little protuberance wich, i suppose, is for the o2 sensor. But it's welded shut! There's no wire running to the front, so this leaves me scratching my head. I'm not getting any engine warning light, so does this affect my car negatively? Do i need a new exhaust?

The O2 sensor is in the driver side manifold, not the cat. That sounds more like the A.I.R. tube, but the rest of the system has probably been removed from your car.

As long as you dont need to pass a visual inspection for emissions consider yourself lucky that someone removed that waste of space emissions system
