Fluval 406 extremely loud

Sounds like it spitting out too much water or something. Like when you boil water over on the stove.

The weird thing is the sound is coming from the canister.

Sounds like air in canister. Tilt the canister forward, back and side to side a few times. It should release the bubbles and run better.
