Do I need a check valve?

seems to me that would be louder...everytime the water left a 45 it will splash onto the next one and so on...
If you must go hard line, there is a product called Dynamat
they use it in the audio mobile industry...

I looked into it, but the easy fix was to go flex hose like most Sumps come with...

Yup, I'm very familiar with acoustic management. Worked in OE car audio for over 8 years. With the zig zags the water won't be able to pick up as much speed and the noise will be muffled somewhat by the bends. Kind of like a stepped waterfall versus one tall one. With the corrugated hose the ribs will also slow down the water but I'm still not sure about hanging it vertically. Can you show me a picture of what it looks like with a flex hose? Maybe I'm just not picturing it.

what about just making the whole pipe angle at like 60* or so so it slides the whole way.

How do I do that and keep the entry and exit directly vertical of each other?

it's not the angle of the pipe, it's in the directional changes of the water that makes the splashing noise.

I think it's more of the kinetic energy of the water transferring to the pipes as vibrations (aka noise). So if you reduce the kinetic energy in small increments the volume of the impacts will be smaller.
