I just got my Focus ZX3 and am looking into getting a cat-back exhaust setup. I'm looking at the Pace Setter Monza Cat-Back and Flowmaster American Thunder Cat-Back. I want the car to have a good sound but I don't want it to sound like a diesel and don't want that high whiny civic noise. From what I've heard the flowmaster gives a more throaty type of sound while the pace setter has more of a purr to it. Is that true? Looking for any input. Thanks.
