That stock intake flows better than 95% of aftermarket intakes out there. Fun fact. Just upgrade the filter to a BMC or K&N one and remove the charcoal liner and you are making more power than a Eventuri carbon fiber intake kit.
So... Ehem can I put in downpipe instead of cat and OPF in Europe? Ofc I'll probably need to have somebody disable shit so I don't get check engine. But after I'll need to do emissions check just put it back and pass?
Quick question, how do you manage to get the up shift sound on this? Is it because of the new downpipe? My 2019 m340i has a lot of downshift burbles, but no ipshift sound
why did you buy a m340i instead of a m3, i have the m440i and i bought it bc it was cheaper, is it the same for you or a differnt. I can think of 1 reason being it has x drive but you could still get x drive in m3 too so i really dont know, please tell me why.
