The port sounds perfect. IT actually is really stiff, plus i kind of reinforced it with glue, accidently at first but it's stiff enought by itself, but i also held it down inside with a bracket.
Don't get any port noise from it just LOTS of air. It crazy how i have 2 of those, both 18" long and the amount of air that the xxx pushes..... can compare to those hand blowers in the mall bathrooms
