    03 FX140 velocity stacks?

    I'm considering buying the R&D VS, but after looking at them closely they just look like the stock stacks but straight and with no screen on them. So, my question is: should I just remove the screens on my stock ones or spend $54.02+SH for the R&D ones? I already have the high flow R&D filter installed.

    aaaaaa that was exactly what i did after comparing theirs and the mines w/o the screen. they look the same. just remove the rivets and use OE rubber.
