I just spent three hours running "honey dews" in my R8. The Milltek exhaust is simply musical in it interpertation of the 4.2 FSI V-8. The symphony going on behind me is AWESOME. Absolutely, positively better than my RS4 with Milltek. Not too loud, very masculine, burbles between shifts, barks if throttled and sings at highways speed. The sound of the R8 and Milltek makes one shift up and down for no apparent reason other than to hear the V-8 music. And the throttle response, thats a whole different subject!
