Headers

Hey guys, when ordering headers, should I go with a 4-1 setup or a
4-2-1? Where will I have the most hp increase? So far my mods are just a magnaflow race series exhaust, but I'll also be upgrading the CAI this weekend. Are the OBX 4-2-1 headers on importshark.com a good buy? Some info please....(Also, if anyone has some response to my ECU thread, it would be greatly appreciated). Thanks.

check out the 4-2-1 header from ssautochrome on ebay.

he has done a couple group buys for us, and people are very pleased.
