Need to quiet overflow pipe

[Offalmangler]

Ok, so I have built my DIY overflow pipe out of 2 inch PVC pipe.
This thing works awesome.

I have quieted my vortex by sticking a rubber tube down the inlet.
But the sound of water coming down my pipes need to be quieted down.

Any suggestions?

Build a gurgle buster for it, will cost less than $10 and takes about 10 minutes.

Just upsize this to your needs http://home.everestkc.net/jrobertson57268/HGB/HGB_construction.html

So this would work with my PVC overflow. Keep in mind I am not using a overflow box. Just a pipe

OkR33fer, that's pretty slick. I'll have to make one.
