Downpipe and AP both vary. With the DP depends on brand, if you are buying it new or not catted or catless. Just when buying one, make sure its a bellmouth design. As far as the AP goes, there is V1 and V2, V2 being newer and with more functions and more expensive, $695 is what I paid for mine. Not sure what the V1 goes for.
