There is nothing attached to my intake and  it is loud. I fabricated a filter housing but it did not quiet it down at all.

The air flow needs to be bent twice at 90 degrees.

And you can always stick a regular muffler on the intake. As long as it's big enough to not restrict it will work well.
I usually use two donaldson style air filters in series, that helps a lot too, of course my application is in some nasty dust
so the two filters are necessary for me. I use a 4" one for filter #1 and a 2" for #2.  Dust doesn't get thru and it quiets it right down...

These people have some info on types of material for construction.

I heard the same thing that Richard posted, 2 90 deg bends but I'll probably use Gary's approach since I have a couple of mufflers lying around. (I know this works because I held a muffler in front of my air intake and it was great)
