I’ve just taken all of the silencers out too and I’ve never had a problem. The valve was still left in the exhaust tho to stop any lights and it’s a fly machine it’s gone from 150bhp to 198bhp it’s better on fuel and just drives better. I’d definitely advise mapping your car and getting rid of silencers for more exhaust gas flow and obviously map the ad blue out and gut dpf there’s only a puff of smoke on start up wen cold that’s it. Not even on full throttle.

My 2016 a4 2.0 tdi is mapped up dpf removed and adblue removed and has no lights on the dash
