What's the best cat-back for a daily driver? I want something that sounds nice, deep, throaty etc. when I step on it... I want other people to notice, but I don't want it so loud that it gets annoying, or too much drone etc. I've test driven two stangs that had Flowmasters (stupid me, I forgot to ask what kind both times) and they sounded GREAT, very mean but the drone wasn't annoying at all... too bad I have no clue what they were. What would you guys go with?
