Ok my questions are, the tanabe racing medallion comes with 2.25 piping right? I ask because this is what I have. Now if I was to get the jdm dc 4-1 header, which has a 2.5 collector, would this create a bottleneck affect?? am I better off just getting the dc 4-1 header? btw this is for a 96 ex with a b18c1 and a stock cat.
