Helicopter noise with GMPP exhaust?  I to am wanting to know about this. I didn't think that would be an issue with the GM exhaust.

Generally the louder the exhaust set up the more noticeable it'll be.  There's no way to eliminate the helicopter noise when the truck drops cylinders.  But you wouldn't notice it with quieter muffler such as a magnaflow.

After a few weeks with it, how do you like the exhaust now?
