Code Active Exhaust Valve

Is there any way to code the 135i, exhaust flap to open at certain RPM/Throttle instead of this closing to warm the engine up faster.
What I want is to re-weld this only a quad exhaust system im getting to that it open two tips under WOT or >2500RPM. It must be possible, just wondering how easy/hard it is to do.
