Had my HD tech take off the Ness Big Sucker and put on a just out new Screamin' Eagle open filter air sucker. Looks way better and changed the sound of the exhaust... Actually made it deeper. Ran great, didnt need to re-map the computer either. Sticks out about a inch further than the Ness and has more air intake surface too. Will give it a good workout this weekend. More shiny chrome than the Ness...which is the most important thing of course. Ha!
