OK I know I am not the first to do this, someone had to clue me in, but instead of plugging, crimping, or otherwise disconnecting the vacuum line under the car, just unplug the actuator in the trunk in front of the drivers side tail light. I was a little unclear as to how this works, but it's dead...

So after doing this it worked great for a day and then I noticed that some of my LED's were out or dim on my passenger side. I thought it was my bad luck and thought I would need a new taillight. So I plugged the actuator cable back in and the taillight issue went away. I guess I won't be unplugging it.

probably answered somewhere in the 26 pages of this thread... but does this have any impact on fuel economy?

I noticed slight increase in MPG but only on long drives, steady speed. Why? Because driving around town it sounds so good I probably keep my foot into it more.

I just did this cause I had my bro drive the car around at the airport and heard something funny. Googled and came across this thread. Thanks for the info!

Has anyone attempted to use either a fuel cut-off valve, or some other type of ball valve in line just before the flapper instead of a ball bearing, etc.?


If something like this works then all you'd need to do is flip it on/off whenever you'd like without dealing with hose pinchers or wiring harnesses, etc.

It sounds like "lug lug lug lug lug vroom VRoooM VROOOOM gurgle gurgle snap-crackle-pop"

If that isn't convincing enough, I don't know what is...

That's pretty slick.
I use a surgical hose clamp..

I'm thinking about trying this on my E93. I hope there aren't any side effects for me! I wonder if the unplug method is worse or better than the hose clamp methods?

unplugged it and barely noticed a difference, maybe it's just me, I came from a 2006 Subaru Legacy GT that had no muffler at all, straight piped and loud as all hell.

We'll see tomorrow as a I drive the car.

Yea I actually called up the local dealer and asked about this.

The guy said no negatives to doing it. Doesn't void any warranty.
