Removing the cat should not hurt performance--just the opposite. It'll free up the exhaust flow. Gains will be small, but it shouldn't affect the engine's operation negatively. The downside is that you won't be able to pass emissions inspections.

hi to everyone,i'm proud owner of 97' Infinity QX4
i looked under the car and there's no rear oxygen sensor so i'm wondering if i remove both of the catalytic converter (since i don need to pass emission in my counrty) would i have any problems with the ECU and probably CEL on.???
