I do have one without the scoop that drops down... It's a huge huge filter. It isn't quite at all in fact it is probably the loudest.. It did help with throttle response and exhaust tone, but it didn't do what they said that I am aware of.. I'll find out when I go to get the live Gryphon Tune how much it helped.. If I had to do it over again I would probably go with Volant or a different brand that in my opinion was just as good in quality and less expensive..
