Has anyone gutted or removed their catalytic converter from their Grand Prix? What is the easiest way to gut one, and how many does the Grand Prix have? I have a GTP. thanks

You'd want to mount up some flangs and have a bypass pipe custom made so you can put the CAT in when needed, like emission time..
ALso with the cat out you will need to get an O2 simulator from someplace like RKSport or RSM otherwise you'll start throwing codes.
