Do not do this.
Your car uses an OBDII (on board diagnostics system II) electronic control system. It monitors the effectiveness of the converter. You will get a 'check engine' light if you do this to the cat.

Gutting the converter will not increase performance. If you want to change the sound, try a different muffler or cat-back exhaust system.

You were able to do this on your C4's because all (except for '95 and '96) used the OBD I system which did not monitor cat converter effectiveness.
