That's alright, the only way to know more is to learn, and you're not stupid, we all started out at one time and learned more by asking questions and doing some research.
The purpose of catytic converters (our mustangs have 4) help reduce the toxicity of the gases/emissions that our engines create.
They also minimize the decibal output of the exhaust. A lot of guys will buy an off road midpipe (either h or x) that replaces the piping containing the cats. This will make the exhaust much louder, as it is basically like having straight pipes in that area.
For v8's it's a great option if you want loud exhaust...the sound is already good, it only gets better (if you like loud). But for v6's louder isn't always better. V6's are even firing engines and naturally get higher pitched, so having it louder will just make the raspiness more noticeable.
I'd suggest either keeping the stock cats or buy an aftermarket catted midpipe. They are more expensive than an offroad midpipe, but paired with longtubes and some flows you'd have a pretty nice, mellow sounding v6.
But it's your car, so the decision is yours. As said listen to some clips online, if you can listen to cars in person, that's the best way to hear exhaust.
