I've got the full Berk sport setup and it's loud on a cold start, but quite nice otherwise. Not too loud, a little bit of 'drone' that has decreased with miles.
Do the RR midpipes have a resonator? The Berk does, and in combination with the muffler, it is quite civil, has a nice burble, and sounds beautiful WOT.
