Off-topic acoustics education done. :) That's some witty remark that seems to escape me at the moment. But touché. :) |
hus, RB duals are pretty quiet over all.. I've personally heard full exhaust with RB duals and its pretty nice. Its not loud like some full exhaust with catback...

here is a little video I made with midpipe and rb dual, granted I am single so you do hear the wastegate open at high boost, I am running RE Amemiya TA exhaust right now and it seems quieter than the RB duals, still have to get the car on the road to see if it is quiter though
