Default Question about a header on a 97' Civic DX

Hey guys. I'm starting work on my daily driven 97' Civic DX. I'm not planning on swaping the motor because this is now my daily driver and I want to stay with the stock motor for Auto-x next year. But my question is I've noticed only headers made for the EX and none for the DX. I know the cat is in the header so I'd have to buy a cat for an EX and re-route the O2 sensor, but will it run like crap? I put a DC header on my 92' CX and re-routed the O2 sensor and it ran like shart. So I put the stock header/cat combo back in and it ran fine. I'd like to put a header on my 97' DX but don't want to spend the $300 for a header if I'll have to take it off because it will run like ****.

The header will be used with an AEM cai and A'PEXi WS cat back for a DX. Thanks for any info anyone has!

Mine ran fine with a header setup (on a 2000 CX). I didn't haven any problems other than a check engine light. My brother did the same for his 1998 HX but he cover his 2nd O2 sensor with aluminum foil to get rid of the check engine light.

Well, don't you think there is a problem with a check engine light on? Did it bog down a lot and smell very rich from the exhuast? Looks like I'll just stick to the stock header/cat combo.

Thanks for the reply.

Nah, I'm not going to swap. I know all D-series headers are the same and will work from 88-00 civics. What motor does the CX have? I've got a DX with the D16Y7.

Why would this be? I just did this on my 95' Si, extending the O2 wire, and it runs better than stock with no cells. Also, if you buy a used dc header, you don't need to spend $300.

if you look around there are a few companies that have made a header with 2 o2 sensor holes for this very reason (althought it removes your cat). i have a ractive one on my lx and the other was kamikaze. I presonally am not a bi fan of ractive stuff but it does the job pretty good i think i got mine for right around 200

I'm only going to put quality parts on my Honda. I've had a Ractive axel back exhaust on my old civic for a while, it worked pretty well, but I like the quality of good new parts. And I'm tired of getting screwed on eBay trying to buy used parts...

No one believes me about my CX when it ran like poo except for my friend who saw it. I had and AEM shorty-DC 4-2-1 header- OBX High flow cat and A'PEXi Dunk cat back. I think it was because I had no cat, and basicaly just a resonator. But for the new set up I will definetly run a cat. I though it could have been a "back-preassure" problem but I got flamed for thinking that. Because the stock CX motor only puts out 70hp. But I just know it ran like crap with that set up untill I put the old header/cat combo back on.

Now what about the header with a cat and my new A'PEXi WS2 cat back? Will a stock 96-00 EX cat fit right in there?

Thanks again guys for all of your help!
