I recently bought a 1977 KZ1000A1  w/Kerker exhaust system.  It has the Kerker Quiet baffle.. My Question:  Is this a 2 piece baffle?  Can the Quiet system be removed from main 1.5" Kerker baffle??  

So far as I know, Kerker never made two-piece baffles. You have a choice between one of the three baffles offered, or a straight pipe.

Back in the day, the first thing we did to a Kerker was remove the fiberglass from around the baffle.  Otherwise you'll have to change to one of the other baffles as TexasKZ stated.  My choice was the race baffle, I think it was 2 1/2"

You can take the fiberglass packing off from the baffle. I’ve also cut down the baffle itself a couple inches. You also can get a competition baffle or run without one. 

The whole subject is quite baffling, you could say that I'm completely baffled. Though I have heard that the path of least resistance is the easiest one to follow.....
