The easy solution for me was to clamp the valve in full open position. No more rattle noise and no v4 drone either. I used a portable scope to run through the exhaust ( removed clamp near flex coupling) to verify the full open position of the adaptive valve. See pics. Full open, normal (mostly closed) and full ccw.

The flapper on my 2017 , 5.3, ext cab started making a noise at start up recently. 3500 miles on the truck. After reading this and other posts I decided to clamp it to full open position by taking a piece of aluminum sheet metal(about 1/16”) , cutting to 1.25” wide x 4.25” long, wrapping around the valve and securing with 2 hose clamps to the full open position. Noise at idle is gone and no humming or helicopter noise during 4cly mode while driving. Might be a dumb question....can someone confirm that full rotation to stop in clockwise direction (facing the val ve, from pass side, muffle to the left,)against the spring is in fact the full open position?

Just completed my install of the center console. Love it. Definately worth doing if you don't need the jump seat. The steps and comments on this forum were very helpful. Ended up taking me about a 8 hours total. Got all the parts from gmpartsheadquarters.com. Shipping was 4 days. I have all outlets up front working, LED under lid and the 3 usb's to play music, pandora and charge devices. Both 12v outlets in the rear and storage part of console work. I did not connect the usb, sd reader and aux jack in the under lid storage compartment. Not important to me. 4 usb's , 4 12v outlets and the AC outlet are enough. Removed the jumpseat wire harness complete in tact(a pain just everyone says), spliced wires in for the rear most outlet, added about 6" of wire to the under lid outlet, zip tied it to the new console harness and plugging back into original under seat area. The mini usb, comm plug and 12v outlet ( originally connected under lid in jump seat) all plugged right into the front panel. The 2nd 12v and 110v outlets get the connections from center stack up front. I tapped into the front 12v outlet to power the LED light (always hot). This approach might not be the best for all but it leaves both wiring harnesses mostly in tact, allowing for later mods if needed. I now have my jumpseat for sale on ebay if anyone is interested. One other note: you can attach the front bracket 7mm bolts (4) without removing the radio bezel and lower piano switches. Just need to reach a little to get the top 2 in.

Hey Jchildress, I have 2015 Lt with black leather, jump seat (500 miles on truck) and live in Maryland. Let me know if you are interested in some type of trade.

I am close to ordering the parts needed to do the swap. Before I do, would anyone in the Mid Atlantic area be interested in trading their black center console for the jump seat w/console? I have the bench seat in black leather. My Z71 dbl cab has 350 miles. Let me know soon if interested.
