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.
