well it depend on who make the filter too, some one in my Legend forum actually involve a test between universal 3" cone K&N V.S Weapon R. supprise the weapon R make more HP on the Dyno lol.
Nice man.. i was just seeing if it would work.. right now my intake already rips pretty good and sounds good as hell.. so far ive only spent like $50 total on a good pipe and filter.. not looking to spend sooo much for a few more HP
