2004 Cat & Flex pipe VS 2000

Johny · Post by **Johny** » Sat Oct 09, 2010 6:44 pm

I was just wondering, since my dad just got a 2000 neon as a spare parts car for my car. Are the cat and flex pipes the same? Would I be able to put the 2000 on my 2004?

Thanks

They are close, but the 2000 is prolly only 2.00 inch, instead of 2.25. Also, if the 2000 is ULEV it is not a desirable thing to have. Unless you can sell it to our California members that need one. They are of some value as far as that.

So yeah, if you don't mind having to adapt the 2" outlet to the 2.25" mid pipe, it will work on a 2004.

Also there is very little except suspension/sheet metal/MTX transaxle out driveline that will swap over. The engine bottom end will not because it is different than the NGC engine. The wiring and PCM also are not compatible.

A 3 speed ATX might work with an NGC MTX pcm tho.

'Ultra-Low Emissions Vehicle'.
It's a CA.EPA thing.

Most cars are built to the "49-state" federal standard, the CA. standards are tougher, and use some special parts. <-(which can be SUPER expensive to those poor CA.residents.):(

Ah haha I see. Is there any downside to adapting the 2" outlet to the 2.25" mid pipe? Any power loss, noise, ect?

The problem I can see is someone coming up with a way to lock the converter. I know there are some converter lock up kits out there, but they would have to be adopted to the Neon's 3 speed.

Do you mean 2 " into the 2.25" ??
Or 2.25" into 2" ??
( Starting from the engine, and going downstream )

I believe he means using the 2000 two inch down pipe/cat on his 2004.

In bone stock form, you might loose a few hp at the higher rev levels. For normal driving, I don't know that you would notice, depending on why you need to use the '00 parts. If your cat is clogged, it will feel like an improvement regardless.

It isn't going to harm anything, except a little top end power. And if you have an ATX, it may not even be noticeable.

If money is tight, use it until you can afford a "proper" cat. Might as well use what you can from the parts car.

Could probably be wired up to a regular switch, but from what I understand, the neon converter doesn't like that so much, and may cycle in and out of lockup.

True, but I'm thinking of something automatic so you don't have to constantly remember to turn it on and off.

Hmm alright thanks for all the input guys.

yeah the fix is 5 speed swap i heard that removes the convertor lock up issues

This is absolutely true, can't argue with that.

Like Jerry said.... I have TRIED wiring the torque converter lockup to a manual switch.
It 'worked'......sort of.
My results were less than satisfactory.

You would only want to lock it in 3rd gear, and have it cancel with the brake signal, plus the kick down lever. Yeah, it would be a PITA.

The 41te modulates the lock up under 47 mph, so that really throws things for a loop on those. I don't think they put that much effort into the 31th.

Have to agree, the 5 speed has the best lock up of all.
