Here's what I did to mine. Made an insert out of some chromed, decorative sheet metal, backed it with some screen, made a fancy cut-out, and bolted it in. Straight-up, it was too loud for me, so I've been experimenting with an insert that I can "tune" by varying the size of the cutout. Insert goes underneath everything, so it's not even visible. K&N Drop-in, snorkle delete btw.
Photobucket's freaking-out right now--I'll get a pic up later.
