No - but I will say this, when I removed my sleeves (because they were stuck in the closed position, permantly) my car sounded like a 4 cyl at high rpm, when I removed them it sounded like an RX-8...

if you get the sleeves from pineapple racing yes they will change the pitch of the exhuast... sounds pretty cool actually, kinda sounds like when ghey *** vtec kicks in on a honda... kinda

if you want to know if theyre working smear some grease on the rods where they go into the actuator... take your car out and go above 4k rpm a few times... then look under the hood, if the grease smeared theyre working, if not... there not working.

Well, honestly, the low end didn't suffer THAT much, but the top end gain was much better, it had a major rotary pull to it power band wise...like instead of piston lay you in your seat torque it gradually had that increase of laying you into your seat.
Never got it dyno'ed with them removed sadly, not enough people wanted to dyno and it's too expensive for them to set up the machine and only one person run (it's a mobile dyno).
I'm supercharged now, so it won't happen anytime soon...
Let me specify something though, the reason I had to remove mine (when trying to make them work again) is because the acuator rods were frozen solid in the LIM, one of them ended up breaking when we were trying to twist it loose, so I had no choice but to remove the sleeves to leave them always open, a working 6 port system is much better than a full time 6 port.
