How to make my 2007 honda crv louder by exhaust/muffler?

I have a 2007 honda crv and I'm not aloud to get a car, so I gotta do something to it haha, I wanna make it nice and loud to roll with a little more style. If I wanna make it sound good when accelerating, do I need a whole new exhaust system or could I do this with just a new muffler. And what are your suggestions for what brand I should get.

Mount a microphone at your current exhaust, and send its signal to a sub woofer amp. Rumble Rumble.

Try the magnaflow muffler. It will give you the sound and slight power increase. But do not think that exhaust will make a rocket from your car. To make it go really fast you will need more actions. Here is the sample of the muffler: http://www.carid.com/magnaflow-exhaust-systems/magnaflow-mufflers-22045599.html

Muffler but it'll just be loud and run all slow well idknoe what kind of engine you got so?

"aloud"? Your first aim, "haha", after trying to make the Honda more ghetto-like, should be your spelling.
