do 'exhaust mod' with coding on 335i?

is it possible to do the popular exhaust mod, like unplugging the actuator, with coding? i sometimes like the louder exhaust but on long drives on the highway and stuff it can sometimes be a bit much. is it possible to maybe code it to, in effect, 'unplug' the actuator only when in DS mode? if not, has anyone tried tapping into the wires and possibly using some type of relay setup to only have the exhaust open up when in DS?

I believe that the JB4 has this option. Stock exhaust with unplugged actuator is quiet to me, need dp's.

For me, I would actually like a bit more pops and gurgles like the N55 PPK flash. Is there a way to code more unburnt fuel into exhaust during overrun?

i like having the loud exhaust when i want it, but because its so easy to unplug it and plug it back in i've come to like the option of having it quiet when i want it to be. i plan on doing the intake and DP's later

BuraQ is working on exactly that.
