I am pretty sure there are crush rings in the ports here but I am unsure the best way to get them out. I have tried prying them out but them suckers are in good. Any help is appreciated

.
one option is to spray it with wd40, pb blaster or kroil oil etc, the take a small extremely sharp chisel and cut it most of the way thru in 4 equally spaced area . . hen take a hooked tool like a dental pick and try to hook the inner edge to pull it out.

wd-40 and a small pick it will come out, and your best friend will be patience

Ok but there is in fact a ring in there right? I tried the hooked tool but when it didn't come out I wasn't sure if there was one in there and didn't want to risk damage so I figured I'll post up

Yes they're in there. You will probably have to destroy them to get them out.

I know this is a bad question to ask but can I leave them in and run my trike for awhile without putting new ones on and be fine? The reason is that right now I am finishing my build and trying to get the bike running so I can jet the carb accordingly. I am having the exhaust ceramic coated in the spring and I'd hate to ruin a set of crush washers and worry about getting them out if I am only going to run the bike a few times and end up taking the exhaust off again for coating. I know it's not preferred but can I manage?

yes you can leave them in . . at the worst t will have a small leak that will not hurt anything or affect your jetting.
you could even put a little high temp rtv silicone on the end of the pipe before you install it but if you put oil on the gasket you would need to clean it off first or the silicoe wont stick.

A total rebuild only to leave out a $7 set of exhaust gaskets? Do you think maybe you should just go buy some?

use a pick and a small screw driver and pry them out. trust me, you want new ones...

Just remember you left them in there.
They might cause a pop or "backfire" on decel and that might make you chase a jetting problem you don't have.

Never reuse those. I've had to remove them a dozen times. It's a hollow crush gasket, 1 time only.
Just a pick with a hook pulls them out like chicken.
Easy cheesy.....

Do you think that yours are "in there" more than any others ever? I hope not. If so you may just have to buy a whole new trike. Do you think it would be a good idea to keep trying?

I would try soaking them with Kroil then, use can also try (Very carefully) use a flat punch and hammer to bite into them and "unscrew them". It may blow them apart, but then you will have less frozen material to remove.
Good luck.

They will definitely come out fairly easily if you do exactly what I suggested . . Also, once you cut them with the chisel, you can use a thin blade screwdriver to pry them out instead of trying to hook them from behind . . You could actually just make 1 cut then try to pry it up and if that doesn't work you can make 1 more and so on . . The metal is fairly soft and pliable so it will bend fairly easily once it is cut which will make them come out easier . . If you get an end bent up far enough you can grab it with some good vice grips and pull it out.

I'll try that this weekend and let you know how it goes. Thanks!
