A friend of mine has a mac cat-back with a bassani x-pipe w\cat's and it's sounds really nice. Mean rumble at idle and sounds really good @ WOT. His brother has the same set up but with a flowmaster cat-back. I can't remember which one but it sounds good but not a much rumble. A more mellow sound. I have a mac cat back as well w\an h-pipe no cats and it's LOUD but it sounds good but then again I am running 10:1 compression.
