i replaced my intake box with k&n filters, how do i prevent my air pump from making that awful noise without the baffle built into the air box?

Go to autozone and get a $7 little round filter (comes in red sliver and blue) looks like mini k&N and put it on the hose coming out by the Y pipe connector (not the one directly off the pump)
This will get rid of the mooo sound.

You can also use one of those small lawn mower silencers. you can find them at home depot racing.
