Can others with the M Performance exhaust please let me know what they've noticed as far as how it behaves?

I LOVE the exhaust. It sounds amazing with the valves in either position.

But I noticed that the valves kept closing on me. I'm trying to hit my 1200 miles for break-in service, so I've done a lot of cruising around. During my cruise tonight, I noticed that the valves kept closing.

For those wondering how I can tell: for one, the noise difference is VERY significant, especially taking off from a stoplight in sport/sport+ in 1st gear. It's VERY loud. Second, if you double tap the button on the remote, it'll either blink five times (meaning valves were closed, and it's now going to open them), or it'll light up red, then fade off over a few seconds. (which means valves were open, but they're now closing.) This is according to the manual that came with the remote

What causes this? Is it me sitting still at stoplights? Is it figuring out that I'm not at a racetrack, so it closes the valves? Or is it a set period of time, then it automatically closes?

It's annoying having to re-open it often. Has anyone else noticed this?

Can this be coded?
