Alright everyone. I've watched the videos on YouTube and I just cant decide. I've already made up my mind. Its either going to be the Borla ATAK catback or the Kooks catback. I want a nice deep muscle car rumble! Both sound awesome to me! I want nice and loud when I step on it but i want a nice clean rumble on idle. I dont want to wake up the neighbors but I dont mind turning a few heads :bigthumbsup.
