My friend and I both have Meistershaft GTC he has catback and I have the full system we are both catless , I can tell you there is a night and day difference in sound , Actually to the point they sound like they have different engines, between the 3-1/2 pipe and the velocity box makes a huge difference, it gets rid of that stupid crimped section in the midpipe
The system has valve control if you want it Quiet , Driving around town you can keep it quiet you just hear a loud turbo whistle , but when you get on it people outside need hearing protection , it’s very comfortable to drive not to loud at all in the cabin , believe me when I go to car shows you can’t even hear my car compared to a lot of cars out there , the turbos keep it quiet at idle , I recommend getting cold start delete , it’s brutal without it
