Got the unitronic downpipe installed at my usual shop and then flashed stage 2 ecu and TCU at home.
I had a few small exhaust leaks right after the first cat in the original downpipe so I took the opportunity to upgrade. So far, noise levels are the same from inside the car and slightly louder on cold starts. I was worried I might find it too loud but it's very much not the case, most people would not notice it's not stock.
Power increase is not massive but it feels a bit more sharp. Still haven't heard DSG farts though, please I wanted these :D
If anyone is still thinking about this specific upgrade for our cars, this is pretty soft in the realm of performance upgrades!
