I have a 96 ex coupe with a b18c1. All thats in it is a aem cai and 5 zigen exhaust. I plan on getting a dc jdm 4-1 1piece header. I have heard that there is some type of flange that I need to get. Is this true?? or will it just bold on without it. If I do need it, where can I get one, how much would it cost, and how much to weld it on? Thanks .

 

I think your talking about the 2.5 inch collector. Try jdmhondaparts.com
