I decided to detune it and make it quiet again, then I stopped at the 410hp mark. Had to measure backpressure to decide whether I need to detune it more or not. But currently only running 30% wastegate duty so it aint forced performance either. In the very near future the focus will be fully aimed towards the new 9-5 saloon which will get G30-660 turbo and so on. Probably later this estate wagon will get 3.5" to twin 2.5" once I have found a design that makes it very quiet on the G30-660 setup. As 3" aint even large enough for this 19T setup in reality.
@@ArturssonEngineeringexhaust cut-out support in EU0D could have been used to switch between beast mode and quiet mode ;) Hope you will use it in your next build ! ru-vid.comak8ceSzmtUE?feature=share
@@myrtilos I have actually debated to use it, the only thing I worry about is what the car inspection has to say about it. Otherwise use a small 2.5" single rear muffler and just before it and divide into another 2.5" cut out valve to that very thing so I get twin 2.5" at the rear 😂
