the factory dv or any dv valves can be set-up to vent the air to the atmosphere giving the bov sound that you may be hearing...
this is done by simply pulling off the end that recirculates air and let the air vent, could but a little breather filter at the end and then simply plug the bung on the intake
@philliesNdutches1 I'm not sure what they did I asked my friend who worked at the BMW store where I could get a blow off valve installed, and he told me he could tweak something right here and it took about 15 min and this is how it sounds.
Its just the full exhaust from for the 335i from magnaflow also im not sure what stage it is because the previous owner put it on.. for the blow off valve i had a friend at the bmw store tweak that for free.
impressive sound..would like to know the magnaflow model and do you just have a S1 chip or better? would like to replicate your performance if possible ...great job
Do you think this exhaust would be ok for a daily driver, or is it pretty loud? It sounds amazing regardless.
