i have an 01' civic LX with a D17 motor. it has an after market exhaust already, and a ram-air intake, and i would like to complete the air flow.

something fairly decent, and cheap preferably.

*nothing damaged please*

i've never installed a header before, so i'm not sure if i'll need a downpipe or not. if i do...i need that too. LoL

thanks guys!
