When porting a box with an aero port, would using 45 degree and 90 degree bends effect the tuning frequency? Or would it be the same frequency as a straight port of the same length?

i think all that matters is the correct length

All that should matter is the length. Make sure you measure down the middle of the port and not on the inside or outside of the bend.
If it is an outright SPL enclosure--I would wonder if the bend would effect the air flow enough to cost you a few tenths or so. I have absolutely no clue if it would or not.

To tell you what length is needed to tune the box to between 25-35hz (and that is a big difference), we need to know how big the port is (diameter), and how big the enclosure is.
Do a search in the sub/enclosure section and there is a webpage that will do the math for you.
Or if you want to learn something, go to the JL Audio website and look under tutorials. It gives the equation for determining tuning frequency.
