sorry to hijack, but i just have a quick question (searched but had no luck..):

i have a 328Ci and i'm about to put some ebay headers on it. how much hp would the new headers alone with the stock 328 exhaust add? also, say i were to get 330 headers and a 330 dual exhaust, how much hp would that add?
