Running Without A Catalytic Converter. Smart?

2000 V70 GLT… was wondering if I could just have a muffler shop cut out the converter and weld a piece of straight pipe in place of it? My state dosen’t have any emission laws. Will this effect the drivability of the car? Thanks in advance. Any advice about this subject would be greatly appreciated. The cost of a new converter is approx. $1100, and a piece of straight pipe is around $35 to have put in.
