Exhaust closes in sport mode

So I noticed that in sport mode, the exhaust flaps stay open at idle, then close between 1k-3k rpm (unless it's a cold start, then they are open for first minute or so) and seem to fully open at 4k. Is there any way to keep the flaps open in sport throughout the entire rpm range or do you have to disconnect the vacuum lines, leaving them open in normal mode?

yes, you need to disconnect the vacuum lines in order for them to remain open during the whole RPM range

Do you disconnect it from the muffler side or toward the engine? The one on the muffler seems hard to get to with your hands. Where is the other side located? Anybody have a picture?

I disconnected on the muffler...just pulled up on the hose until it came off. I then put a vacuum hose cap on both the vacuum hose and the nipple on the muffler. it is pretty tight in there though. if you need more room, you can remove the black plastic "diffuser" portion of the rear bumper.
