Speaker Port Tubing

[Mustang Man]

I am looking for port tube material of 8" diameter. 6" seems all that I can find. Can anyone point me in the right direction?
Thanks,
MM

A quick google finds this? Unless you want a actual speaker port then ignore this.

Then if you have time etc then you can put a flair on it like this for a more professional look, plus the possible sound improvements.
