Hello,
My name is David and I am the owner of a new to me x4m in sophistico grey!
i love the car, i changed from a silverstone ii f80 m4.
I miss my m4, but fair to say the x4m is a fantastic all rounder. Except it’s sooo quiet. Any tips on exhaust mods. I see a lot on other forums but mostly from users in the USA who don’t have the dreaded OPF filters. Not sure a res-delete would have the gains I am after; and not sure I want to code and remove the OPF given warranty concerns?
tips welcome. Photos attached 😉
