Hey guys, I recently picked up a VX, and I'm having trouble finding information on it. I've searched the forums here and I'm coming up blank. Rather than start a new thread, can anyone point me in the right direction? Does anyone have any links to sites with info? Or is there just not a lot out there for the VX?

What kind of info are you looking for?

Specifically exhaust related stuff. In a nutshell, the stock exhaust has rusted and fallen off basically. I'm going to slap something ebay on there, and I know that the DX/Si exhaust won't directly bolt up. I'm figuring that I'll need a "cat delete" test pipe in order to go from the factory manifold to the aftermarket exhaust.

Although I'm not looking to spend the money, my other solution is to order a new header, and bolt that up. That will eliminate all of the cats on the car, but emissions aren't a concern where I live. If I go aftermarket header, can the 5-wire O2 sensor be extended and still function normally?

My ideal setup would maintain the factory manifold, so what exhaust parts do I need? I'll be happy to create a new thread for this. I apologize to the OP for thread-jacking.

The information you'd like to get a hold of is in the 92-95 factory service manual.

The VX and the USDM CX (D15B8) share the same Exhaust Header/Catalytic converter setup.

And no to the relocation of the 5 wire o2 sensor. Wide band I've read has to be close to the top of the exhaust chain to be effective. On the 4-2-1 header setups, the only spot that reads all 4 cylinders is down under the car just before the cat. I think that may be too far to be effective for a wide band o2. The upper spot some 4-2-1 headers have only read from #4 cylinder which may work but won't be the same as being in the collector of a short 4-1 setup.

You can find the header on USDM CX for 92-95 civics if you want to stick to stock.

Thank you for the info TomCat, it is appreciated.

What I really need to know is specifically related to the installation of an aftermarket exhaust with the factory manifold. I'll check the service manual like you say, but in my experience, they don't really pertain to aftermarket setups. I'll download the manual and check really quick.

TomCat39

I don't believe you will have much luck doing after market with the stock manifold.

To do aftermarket you will have to get a new header which will put the catalytic converter under the car like the DX/EX and Si of the 92-95.

I've never seen any sort of aftermarket cat delete exhaust system for the CX/VX system. I've always just seen you swap the manifold (header) out to be a DX/EX/Si setup.

Moved to your own thread so as not to derail the other poster's thread.

Thanks for making the new thread my man. If you have the power, can you delete the other new thread that I created? Thanks in advance.

i had a 92 vx. I replaced the manifold and cat with a 92-95 ex header. It replaces the cat and bolts right up to the exhaust with few modifications. Yes the 02 sensor is only on one header tube but i never had any issues with it or cel's. Wish i could say the same with my 97 cx.

At the time i had my vx there was very little available for it. One good thins is that most of the 1.6 ex stuff will interchange. I was planning on putting an ex tranny in for the gear ratios as the stock vx tranny would hit the speed limiter in 3rd gear at about 120mph.

The benefit of a VX is its great fuel economy. Putting aftermarket parts on it to "improve performance" is a waste of your own good money, and removes any benefit of the original setup, geared towards great fuel economy. Replace the stock manifold? Nobody wins. You spend more money burning fuel that you didn't have to in the first place. Get it all out of your head, and get the correct parts for the car.

The VX rivals the Prius for fuel economy. Let that sink in for a moment. It took 15 years to design a hybrid that has the same rating as a 92 Civic.

Your problems with your exhaust are basic, and solved by spending under $100 for a replacement aftermarket stock exhaust made by Walker or Bosal. Check rockauto.com, they're listed there and are an exact fit, all the way to the A-pipe. You keep your stock cat converter.

Ultimately, if you want a better go-fast machine, modifying the VX engine is a non-starter. Putting another engine in there is the best way. RIP VX. Another one gone.

^This man speaks the truth Save all the VX's!

anyway I modded my exhaust a while back regrets yes I have meant to go back but I have been lazy to do so. Then I went on to selling the VX wheels I still get more than amazing MPG doe.

I see a lot of red VX's. Was that the primary color they painted them? Mine is red also. Rarely do I see white, black, or any other colors really. Nice car!

Green and white were the main two other colours. There was a blue (US only); very very rare stock VX colour.

Eddie

There is a blue one rolling around my neighborhood that thing is destroyed. Absolutely rusted out. It's such a shame :tear:

Thnx good sir

Got any pics of your VX?

surfingisfun001

Here she be...

Eddie

Ah so clean man. Mod lightly if you must but keep it clean take good care of it

surfingisfun001

No mods other than window tint and alarm. My last civic was stolen. Other than that I will keep it all stock and take very good care of it!

^ Needs the stock lip back on!!

surfingisfun001

Is this not it?

TomCat39

The one thing I would do right away is to pull the rubber lips off the rear wheel wells. I believe they catch and hold water on the rear fender lip just speeding up the rusting that happens on these 5th gen civics.

Your rear fenders still look to be in pretty good shape, would want to prolong that for as long as possible.

surfingisfun001

Good to note. One of them was already off. Thanks.

No, this is. There's nothing there in your pic (just the black bottom of your bumper).

surfingisfun001

Do you know what % of light let in the stock window tint was?

surfingisfun001

Oh ok

egsleepercivic

same as the ex/si lip, you can still get them from the dealer for around $100

It appears that you "get" what I'm trying to do. I just want to replace the rusted off factory exhaust, without going to a muffler shop. I'll check out Rockauto. I'm hoping that they sell a "bolt on" kit. I fear that some of you may have gotten the wrong idea about what I'm trying to do here. I have no intentions of making the VX "fast" nor do I plan on doing anything with it other than drive it for the superb fuel mileage. I simply mentioned ebay as a source, since I'm trying to own this car on the cheap. (Lord knows with all the other cars I have in the garage, I can't afford to keep getting crazy with them.) If I want a spirited drive, I'll drive my R.
