adding a 45 in a box especially just one will not make things move around a lot more...

but will it help move air out of the port or do nothing becouse i can tell things move more but dont sound as loud so would you suggest taking the 45 back out becouse after addig it it dont see as loud

you didn't do a true 45 so it doesn't help much.. and there is no way it did anything audible.. it very well coulda added or subtracted .1-.2 but you wouldn't be able to hear or feel it..

Being an SPL competitor and someone that tests things such as 45 degree angles, I would recommend not worrying about them too much.

i put em in all my boxes, all corners also adds strength, but like said 1 will not make a diff
