Put a 90 degree elbow for the termination and then the regular rain cap.  Works fine for me.

Thanks for the reply, but I'd like to keep the flow up for dispersion.

Thomas, I have a china cap on my stack....I was recently told that installing a 7 inch around the 6 inch pipe would eliminate the china cap.  the science is that the china cap prohibits proper dispersal of the smoke and thus makes the air flow, flow better.  The china cap is like breathing with your teeth clinched instead of opening the mouth fully.  The wider pipe would catch the rain/snow and drip down the outside of the inside pipe.  When I asked, wouldn't the rain go down the pipe???  He said, as the planet rotates, it's impossible for the rain to go straight down.  What do you think????

Hey Jonathan,

 

Thanks for the reply. I am familiar with the 7" around 6" pipe theory, but I am still skeptical. I guess its time to build a prototype.
