Hey everyone, I just wanted to get some different opinions on which cat back systems sound best on our cars. I currently have a full Mac setup; shorty headers, o/r h, and cat back. I love the way it sounds, but my tailpipes are badly rusted so I'm in the market for something new. I would have no problem buying Mac again, but just wanted to see if there is something else I should be considering. I've been away from Mustangs for a while so I'm not up to speed on everything that's out there now. Thanks!
