So after fitting and running this for the last two days I can report back and confirm that this system still produces pretty much no drone at all on motorway running, and normal pottering around town sounds very similar to the resonated system (powervalve sport system with 200 cell cat), but when you step on the loud pedal, I can assure you, all hell brakes loose! I wasn't aware of how much the centre silencer toned the noise level under load! Dsg farts/pops are as the video on page 1 (without a dsg map that is) and they sound nice and aggressive as I had hoped!
If you are looking for a Jekyll and Hyde system, this is the one for you!
