Stock vs. High flow Catalytic Converter?

[jeeplover88]

Hey guys, I have a 88 4.0, and I'm looking for a little more throaty sound. I currently have a Flowmaster 40 on it, and it sounds great! What would be the pros and cons of replacing my stock catalytic convertor with a magnaflow? Or, any ideas how to gain some horsepower, and make her a little more throaty? Thanks guys! :Canadaflag:

The high flow cat won't hurt but the throatier sound you want will come from replacing the exhaust pipes with the next bigger size.
