I personally like AWE Twin 1 exhaust because there is only one mid muffler that you cant see when you look at the exhaust tips. I dont like the look of a big muffler hangin out underneath the bumper. Sounds pretty nasty too. Autospeed true dual with 89mm tips sounds amazing. UUC VM3 could be my favorite sounding exhaust system. Apparently they are bringin them back or the VM1s

 

Has anyone put the 14816 Magnaflow mufflers on their S4? I had it on my A4 1.8T and it sounded great! I am thinking about doing that to the S4... except running dual exhaust!
