2nd Gen. 1&2 Series (2011-2021 | F20,F21,F22,F23)
Hiya,
I own a 2017 B48 1 series (2.0 petrol, twin scroll). I am wondering if anyone has any experience taking out their PPF/OPF and/or their cat and can give me any advice on the tone/volume change this would cause? I want some more volume and want to be able to hear my pops a little bit more...
