I just did this by disconnecting the plug in the trunk. Works with no errors so far. Noticeable difference in sound at lower RPMs with the window open, can't tell a difference with the window closed. Overall very happy for the 5 minutes it took.

My young neighbors from Germany asked if my exhaust was stock, I said yes but they looked puzzled, and all I did was stick a golf tee in a hose.

I know that when some design exhausts and headers......they lenghten/shorten the tubes, use larger/smaller diameters...etc to get gains in certain areas.
So I ask...does the flap open and close under certain loads, rpm's and such or does it stay closed at low rpm's then open above that with no effect on other gains?
I just wonder if doing the mod you might loose out a smidge somewhere else like low end torque and just gaining sound.
