Okay I'm about to order my new header for my b16 gen 1 today. I have a dc sports 4-2-1 header the thing is when I jacked it up it has 2 o2 bungs I think. It has 2 sleeves it looks like with wires coming out but dc sports only come with 1 bung hole. The previous owner did this and I have no clue what to do. The aftermarket headers for a 94 delsol and 99 SI DOHC all have 1 o2 bung right in the middle by the outlet. What do I do here?
Also I'm trying to decide which header to buy. The megan racing header is 120 and 135 with a cat delete but it only has a 2.1 outlet? The JDM replica type r is 200 and the dc sports 4-1 is 235. Which 1? Not sure about the outlet size on the dc I think the r is 2.5.
Also I have gutted my cat but I have a apexi catback I believe its world sport. Are all aftermarket exhaust systems 2.5 or is mine? Also it has 2 cat looking like reasonators after the cat are this restricting performance or should I remove them. The car is'nt loud at all and has no farty sound at all. I love the exhaust sound but I wanna make sure its flowing its best.
I also am throwing a check engine+ it seems after getting on it hard on deceleration especially. It only does this sometimes and mostly after running it hard and letting off the pedal.
thanks
