...I was one of the lucky ones to have the S5 since October last year....would love to upgrade the exhaust but having to lease my car would like to keep it completely 'stock' and upgrade to an RS5 next year!!
I too had the Milltek installed but went for the slash-tip instead of the rolled-tip and love it. Love the sound and the looks (though it may look a little more boy-racer than the rolled tips). Heard the AWE system from their website but I still love my Milltek. Highly recommended!
