ok so i have a b16a sir 2, and can get and ITR manifold for 205 plus shipping. will it bolt right up and all lines go into place(smog). and if so should i go with this or shell out the extra dough for a skunk2. and if i do shell out the extra dough should i get the old version skunk 2 manifold or the new one. it would be like 15 buks extra to get the older version over the ITR and then it would be like 70 for the newer version. wat does everyone think. i have the money for whichever one but if they all flow the same then wats the point in spending for the more expesnive.... oh and i plan on goin stage 2 cams in the near future 2. so which one will flow best with those. thanx in advance
