I received 1 set (2) low noise props for my MP but was wondering what would happen, if anything, if I mix low noise with regular props?  Would it affect flight performance and stabillity?  

You should not mix different types of props.

So!  Why would DJI not send 4 props as a set since it is a quad?

Because you might damage only one or two, means you don’t have to buy a full set.

No disclaimer stating not to mix props!  Nothing mentioned when purchased.

So try it and let us know how you get on then

We would not recommend you do that. Please do not mix props. Thanks for your understanding.
