Which intake to my 7A-FE? Options

[Gamebitz]

I want my car (7A-FE) to have more throuty sound it has a TTE Double piped exhaust already, but it could use a more deep sound.

I have been searching for a short ram, but the only one I could find is the Injen Short Ram Intake. In Denmark it's 400$ for the Injen set! Is it possible to find something cheaper that gives the same kind of sound, sorta like this: http://www.youtube.com/watch?v=aKpG9AS6_Dc

I don't want a cold air intake since im worried about it hydroclocking especially in the current cold and wet weather.

Do you guys have any suggetions, which SRI that both are cheap and doesen't harm the engine (not a bad quality one.)
