Which box is better! I want to be able to use my stock filter. Also how much HP increase should I expect? I know graves makes one but I thought that someone else made another!

Thanksalot....... Cash

box-r is the other manufacturer of the ram air box. they both recommend a bmc or k&n filter for best results. there supposed to give about 4 hp at top end. i just did the airbox mod from this forum, by dop[dayofpain]. i also added velocity stacks and made the cut out larger than discribed. this airbox mod on a stock 02-03 made 3.5-4 hp the same as the ram air. i havent dynoed my bike but i can say it made a huge difference thru the whole rev range. hope this helps any guestions pm me.
