Obd0 jdm b16a1 I got two o2 sensors :(

Correct me if iam wrong, that's what this is about ;), but one of my o2 sensors measures cylinders 1 and 3, the other measures 2 and 4.. I would have to convert to a new ecu since with the new header I would have a bung where all four meet, then another after cat? I has no clue :( I guess...

Iam at obd0, 1 would be an upgrade sadly lol, I really wanna get headers but have no four about it

New question!!! Same thread.. if I switch headers to a rmf replica, will I have to convert to obd1 because my o2 sensors are moving? I really just need to pass emissions and iam trying to knock out my whole exhaust in one swing

Thank god! I sure hope so. If he spent 2k on exhaust, I would love to see his engine bay :P

Alas poor yorick! An answer prevails! Ye lasses can continue on with the butt hurt now. On a side note though, u paid $200 for exhaust "tips"?

I will get ass raped if the.cops decide to pull me over.... Knock on wood... With the tax return I really wanna get rmf headers, eBay replicas, and goto a muffler shop. My setup, unbelivably, sound really good and pretty quiet yet deep.. do I really need a muffler? Or just cat. , glasspack, then...

Ahaa. I would hope so. But I just realized my tax return comes in next week! Should I still go muffler shop or buy an actual aftermarket maybe eBay? Anything cheap and emissions passable?

And any recommendations on a high flow cat that would damn near guarantee I pass emissions? :P

Sweet, anyone know if lowes has pipe? Autozone has like, 1 foot segments -_-

MOits a 91 civic dx sedan with a b16a1, and iam pretty low on cash and time. My tag is expired so I have to pass emissions before I get pulled over :(

I can either spend 400 on exhaust for a name brand, or take my car to a muffler shop to weld me up an exhaust.. I currently have, don't laugh ;), stock headers, 2 catalytic converters with only half of the insides (they both broke so I took it out), a cherry bomb glass pack, and then it goes...

Before that I think I should try my o2 sensors? Anyone have part numbers for a jdm b16a1 obd0?

Okay so now iam desperate... Anyone know if installing an aftermarket exhaust will help? Cause I currently have a horrible self made exhaust... And it has a gap right after the headers.

Well, I replaced my cat, did an oil change, changed spark plugs, used a can of seafoam, got my engine pretty hot before the test, and even put a little denatured alcohol in my tank. After all that my nox reasoned are still around 2000 and they need to be 1000.... What the Hell can I do. I have...

I really have no clue man. I plan on the car being n/a and for a dd and an Autocross car. And the header was supposed to say hmf header

So there are two things I have little knowledge on, brakes and exhaust. I drive a 91 civic sedan dx with an obd0 jdm b16a first gen. I hear that the hmf header will give me 15 horses by itself. I also like the sound of the his hi power. That's all I know. If I get the hmf header and the his cat...

I did a full tune up about a thousand miles ago. After cat should I advance or retard timing? And would using regular gas instead of premium make a diff?

So pretty much I drive a 91 civic dx sedan with a b16a first gen, I gutted my cat, then moved to my hometown where I forgot I had to pass emissions. Here is what I got at the emissions test.. also they put me in as a 1.5 and I only drove like a mile after I got off work to get it done so the car...
