Slant heat riser block off/delete?

Anyone have pics of their heat riser block off or deletes? I'd like to get rid of that. If at all possible I'd really like to cut it off and weld a plate or something of that sort.
I have a setup to block off the heat to the manifold along with hoses and a valve to be able to turn it on and off so you can put on in the winter you could probably use it
