Bending Aero Ports?

[captainhook426]

I'm trying to design a new box for my truck that goes under the back seat, but in order to get enough volume I need an external port. I need to put a 90 degree bend in the port to make if turn back to the front of the truck..

So the question is... Does this hurt sound or output? Does it effect tuning? and Where can I get the parts to pull it off?\

i have areo ports in my setup right now with 90 degree elbows. never got to hear them without the bend so i'm not sure if it effects output, as far as tunning goes you should be able to figure it out by measuring down he middle of the port and inputing that length into torres' calculator. i have the aeroports that are sold on partsexpress.com and the elbows i bought at home depot and painted them black since they were white pvc. hope this helps, pics in my build long, link in sig.
