I've researched and researched regarding what exhaust to use. I have the ex accord which appears to be the same design as the jdm h22a but my downpipe doesn't bolt up to the jdm header/manifold. My h22 didn't come with the downpipe only the header. I'm thinking that I need a usdm prelude vtec header and downpipe and that should bolt up to my stock accord cat ? I'm wondering if I woulda had the jdm h22 donwnpipe if that woulda woulda bolted up to my stock cat?

My O2 sensor is down by where the prelude vtec is so I shouldn't have to change the length of the wire, right?

I see a few ebay headers here...

Which of those will work, if not all?

thanks in advance

 

Get the 92-96 VTEC Prelude aftermarket header. Do NOT get the 97+ Prelude header. The downpipes are not the same length.

You will not need to extend the O2 sensor wires either. It will bolt up fine.

 

So get the vtec header/downpipe combo and call it a day? I assume that any of the one I showed will work.

The thing about it is that I've noticed that the dorman header that fits the prelude vtec also fits the lx/dx/se 4th gen accord but for some reason doesn't fit the ex which I have. Also, it's a 4 to 1 type instead of the 4-2-1 type that the OEM prelude vtec is. The thing that I want to be sure of is that I can get an ebay vtec 4-2-1 and it will bolt up to my cat. That's the only thing I need to be sure of. I'm assuming that all 4th gen accords have the same cat bolt pattern? If they do, then I have nothing to worry about. My other option is to take my stock header and jdm header down to an exhaust shop and have them fix the jdm to be the same bolt pattern as the top of my stock downpipe.

I'm not planning on bothering on trying the dorman model.

 

Looks like I just need an ebay header and downpipe and it will bolt up fine.

"yep tab is correct. i bought a dc header for a h22a and it fit just perfect on my 92 accord"
