Exhaust questions....again

Alright,
I can't decide from a flowmaster super 40 44 or 50. I don't want it to be too loud. But, I dont want it to sound like a Prius. I am kinda aiming for that wrx sound. As far as I am understanding, super 40 is loud, and 44 is throaty and somewhat quieter. And the 50 is suppose to be quieter then the other ones. Any videos of a 44 or 50? Thanks.

 

Anyone at all??

 

I have a 2.7l with a Flo-pro max. It is a stainless steel. It is quiet, but it has a nice growl to it upon acceleration without it sounding annoying. It is a flow-through type muffler. I wouldn't go too loud.
