From the technical drawing, the actuator is right on the exhaust. If you can unhook it and zip tie the link/arm that control the flap, then that should do the trick. However, I think the flap does more than just the sound but also control the back pressure. If you keep it open all the time the torque might be affected a bit. Probably not too bad since it got a lot to spare to begin with. I will try to look into it next weekend unless you get it working and wanna share some photos before that.

Hi nwills, check out photos I uploaded. That is how I keep flaps open. It sounds like a proper V8 now.

The zip tie method worked perfectly. Thanks to Summer78. The small hole in the mounting arm made it possible.

That's what I was concerned with too. It does not come in direct contact with the exhaust but I suppose heat may still transfer via the control arm. Time will tell.

I was thinking about that too, but that is what I happen to have lying around. If it breaks, then I will replace it with metal tie.

I prefer Meisterchaft b/c I like EV control feature. Eisenmann is great too. It depends on your taste, so it is best to check them out in person before committing to one.

I also did the mod tonight! I did not have the m sport exhaust but still sounded very good. However, I noticed a very tiny bit of droning at idle after the mod.....

Neversummer78 and Andreo,

My 650i GC also felt a tad more responsive with the mod. My friend who test drove the car last night also mentioned the same and asked what I did (I didn't tell him the mod).

Did you guys feel your 650i a bit more eager to go and more responsive after the mod? Or am I and my friend just hallucinating........
