I finally got around to putting on my bassani o/r x and ss cat back on. I don't really like it all that much. On my old 03 I had Bassani o/r x and MAC 3". It sounded much cleaner and better quality. I went with Bassani cat back this time because I thought I went the cheap route the last time. I guess I'm a cheap kinda guy. I'm thinking about getting rid of the bassani and getting the MAC again.
