Anyone use the Twin Air brand on there 400ex. I have one on my XR and really like it but all the pictures I've seen really don't show a good shot of the one for a 400ex. Does anyone know about the fit of these filters? Do they clamp on like the oem filter? Can you still use the "canister" that goes inside the oem filter with a Twin Air? What about the White Bros. filter? The Uni filter?

I ran the White Bros. for a while. They are definitely better than stock, but you still have to run the canister (this thing is actually a spark arrestor to prevent fire if it backfires into the carb). I felt that the canister was to restrictive, and frankly I have so many bikes I just got sick of cleaning all those foam things. So, I have gone to K&N with Outerwears on all my bikes, and now life is a little simpler.
