I need to replace my water heater. The current one I have is 57 1/4" tall. I would like to replace it with one that is 67" tall. I can get one shorter, but I would like to figure out how to get the taller on e in here. I also would like to do some type of flexible connection so that I don't have to re-solder in the future if possible.

Here's the pic:

Oh, forgot to mention the water heater top of the new water heater comes up to the bottom of the Blue tape on the hot water pipe. This is not counting the nipple, just the top of the tank.

If you plan on installing taller water heater, you will need to cut off the hot and cold water supplies, angle them upwards and add pipe extensions as long as you need to accommodate new water heater height. Looking at your photo, you will have to re-do the expansion tank connection and the angle stop outlet as well. Hot water side is straight forward. You don't necessarily have to "hard-connect" the heater connections. You can use Water Heater Flex lines that may be lot easier to connect new heater with. Also, make sure your electrical conduit is long enough to connect to the heater. If not, you will need to re-wire that conduit with new wire.

Hope that helps

Would all these additional 90 degree turns add a lot of noise?

Technically yes. Each 90 ell in the system increases friction, and friction creates more noise. But I will be on such a small level that you won't notice. If you are really (really) concerned about increasing noise, use two 45's instead of one 90. That will give you smoother 90 degree transition.
