What Would Happen If I Put On Flowmaster Super 44 Delta Flow & Magnaflow Catalytic Converter


I have an ’05 Grand Marquis with glasspack exhaust system. What would happen if I put a Super Delta 44 Muffler and a Magnaflow/Flowmaster Catalytic Converter on it? It has single, NOT dual exhaust! I want more of a rumble and with just the glasspacks I don’t feel like I am getting all the sound I want. Also, it has the 4.6 V8
I did some research and found out removing catalytic converters are illegal unless under certain siutations?
If my converter is working but I do fulfill the requirement that it is over 50,000 miles (it has 120,000) can I legally replace my converter even though it is working correctly?
