Yes, I just went & looked at my car. How can i actually tell what header my dc sports came from. I have a sir 1 swap in my 91 civic si. I have 1 02 sensor on left side of header toward pass. side. If i was to ever order another header should i order for a 92-93 gsr ? Also what about a high flow cat if it ever dumps on me.

I've never really paid that much attention to which car my dc sport header came from. I was just happy at that time to get my car back from shop taking like a week to swap the Ls in. I did later find out after getting my b16 swapped like 8 mo later that the shop ripped so many people off not really knowing how to do a swap properly cuz the owner said he had so many swaps he had to redo because of so many dis satisfied customers from other shop.Real talk.Money I spent on a Zc ,Ls & B16 I could've had a K swap back then .You live & learn. Not on site much anymore due to I have twin sons now. Gotta buy everything twice. lol

Thanks,
any info would be greatly appreciated
