So I have a b20b swapped into my ‘97 ek hatch and I needed to get a new header and exhaust due to rust leakes. So I bought an Integra header off eBay for $60 and it bolts up just fine but the problem is that where it should bolt up to the cat points toward the ground so if I put a cat or test pipe on it then it will actally scrape the ground when I’m driving.

What I need is someone who knows what header I will be able to run that will not point towards the ground. Also, I’m going to be running the yonaka catback exhaust.

96-00 Honda Civic 3DR Hatch CX/DX Catback Exhaust

As you can see it has no place to bolt up to a cat or test pipe so I need a header that will fit bolt up wise and length wise to run the yonaka exhaust.

I need advice from someone who knows for damn sure what header options I have to work with that will fit for me with no problems.

I’m at school right now so I will post pics in about an hour.

thanks in advance

edit: I‘m using avid motor mounts if that makes any difference

the 96-00 hatchbacks had the cat on the header, DX/LX/CX. None of them had a separate cat. You'll have to take it to a muffler shop and have them cut and weld it with a 3 bolt flange. in order to mount up an si/ex style cat.

I see what you’re saying but if you look closely on this exhaust it’s a 2 bolt flange not 3. So I’m hoping I can find a header that can bolt up directly

That's normal. What Tony said still applies. The exhaust b-pipe bolted directly to the a-pipe when the Y7 was in there. You'll have to go to a muffler shop to have them shorten the pipe and apply the correct flange to mount a cat, or get a test pipe... or get a exhaust that is intended to be used with a cat under the car. I believe A'PEXi exhausts are configured this way, but it's literally been decades since I bought one for a hatchback so I don't remember.

Straight from the page you linked:

*Please note this model is a direct bolt on fit for the USDM model Civic only. Canadian models of the CX/DX use a catalytic converter that is not installed in the header. In order to fit Canadian models our mid pipe will need to be shortened - any muffler shop can accomplish this with minimal cost.*

FWIW, I was able to temporarily bolt up an A'PEXi WS2 to my sedan while it still had the Y7 in it, using a gutted EX/Si cat to fill in the extra length. I do believe the A-pipe is longer on the B18 manifolds though, so that will need to be considered.

i duly concur with everyone.

just had my b20vtec installed into my DX hatch (1999 ej6 hatch)...

basically, i ran into a problem where the exhaust i had was not correct, as well. my headers are 4-1 2-bolt flange style.
well..... i bought a used EM1 2.5" exhaust, but the muffler piping was far too long and the muffler was way too big-

so, on my exhaust, it had an under-car cat, attached to the new exhaust, but it would be pointless to use 2.5" exhaust, with the 1.5" cat.... so i had to buy a new hi-flow cat from them, so they welded a new flange to the purchased exhaust (was a 3 bolt design) and it went from


headers (2-bolt) to cat (2 bolt one side -> 3 bolt other side) to a 3 bolt catback, and they had to weld piping to my new muffler, which was a 3 -bolt, as well.

ended up costing 400, but i'll tell you what...... my car sounds VICIOUS now.

b20v, 4-1, high flow cat, 3ft resonator, to a vibrant muffler.... sounds AMAZING. none of that raspy yonaka / ebay crap.

i used the godspeed 4-1 headers, piping from an em1 Megan Racing stealth kit, and a vibrant muffler. i love the growl and she purrs like a champ.

originally, when the swap went in, it was the 4-1 connected to the restricted stock DX cat/exhaust which was 1.75" and was running like dogshit.... now its 2.5 straight back and god, its nice now. pulls so hard too.
