Muffler delete or Cat less down pipe
Hi All,
Just got a 2020 M340i and was wondering what is better for sound, pops, burbles, ect. Should I just do a muffler delete, but take away the valve that switches between modes or just replace the downpipe with a cat less one? |

Do you know how can I do this? I'm assuming it will automatically make it way better sounding even when completely STOCK?
