XD2 Header

[04 elantra cvvt]

Alright guys. Y'all have never let me down in the past, so here we go...

Does anyone know which header out there will fit the XD2 with the least amount of modifications? I am not too worried about cost, (as long as they aren't 1,000 or something stupid like that). I want the best quality and the best fit for the money.

Thanks a lot guys!

No modification:

EvoFusion

KSpec, any version

KDMStuff.com, any version

With Modification:

eBay SSAutochrome, or OBX, you'll have to add about 6" of pipe to reach the catalytic converter.

I personally want the GT header from KSpec, I love the tubular look, but it's about the money.

I would say, go for a 4-1 type header, the difference is stunning.

Thanks... I was looking at the 4-1 on sharkracing. I am not too sure about theirs, because they don't specify XD2, and I know that the exhaust ports are slightly different on the cvvt head. Kspec is the only one that offers a difference for the cvvt head.

Dude,I had a 4-1 for a 97-01 Tib on both my 05xd2 and my 06 Tib.I loved that header.It dont matter what header you get,they all fit the same as far as ports

I heard that the outside 4 holes have to be enlarged with the cvvt head. Was this wrong?

How does that difference manifest itself?
4-2-1=? over stock
4-1=? over stock

Yeah, I've always wondered what the difference was between 4-2-1 and 4-1 (other than the piping, obviously)

[evan938]

4-2-1 is better for an auto, 4-1 better for 5 speed. its going to affect where the most torque and peak HP is present

K SO where i read that more tq is available down low with the 4-2-1 is good for the auto. How can that not be good for a manual as well? I sometimes prefer to shift down low so more tq would be better.

As far as drilling out the holes, it's only necessary if you purchase the Tibby header for an RD Tibby. It's the 2 outside holes to the left, the 2 to the right. And it has to be done on all XDs, including XD2s.

Also, if you buy the RD, or even a GK, header, you still have to weld to reach the cat. You are only talking about a $50 job at the very most.



The differences in header design, 4-2-1 and 4-1, are not Hyundai specific. They pertain to all 4 cyl. engines. I have a 4-2-1, as not many 4-1 are made for the Beta motors, at least within my purchasing range at the moment. My next header upgrade will be the GT ones from KSpec, which are still 4-2-1, but the runners are stepped, which will give me the torque (like a 4-1) back that I'm missing now.

thanks evan for explaining the difference between the two
ill have to save up for headers

[Silentwolf]

:confused: Info i got said the 4-2-1 header gave more torque than the 4-1 header?

This off SR
"Our 4-2-1 header will increase power throughout the powerband, but especially in the low-mid RPM range. This header is especially effective in automatic transmission cars"

"Our 4-1 header will increase power throughout the powerband, but especially in the high RPM range. This header is especially effective in manual transmission cars."

What i really dont get is how a header can be more effective for a certain tranny?

I have a manual, and would like a little more power down below 3k. I normally shift in the 2-3k range. So would i be wrong in going with a 4-2-1?

4-2-1 is what is most commonly available, so you'll probably end up with that. the only thing better than a 4-2-1 is a LONG TUBE 4-1 but I have never seen one of those for an elantra.

you didnt consider the key header you had on your car a long tube?

[Keyan]

It is. BUT it was a long-tube-equal-length 4-2-1 header.

The best for any high reving 4 cylinder is a long tube equal length 4-1...it's been proven on many hondas and I think it would work just as good on BetaIIs.

I never enlarged the holes on the header I had.

God i feel like a noob right now.
Long tube 4-1??

Whats SR's 4-1?

[Keyan]

if the tubes meet up infront of, below, or behind the oil pan I consider it a "long tube". If they meet up just a couple inches after the head, it's a short tube header: (ie oem echaust manifold is a short tube because its a short distance before they meet up so they can go through the cat)

you are confusing that with the mitsubishi 4G63 head. and even then, it's only 2 holes you have to oblong, not 4.

[BColeman]

No, when using the OBX header or SSAutochrome you either have to do a lot of enlarging on 2 holes, or some minor enlarging on 4 holes. I always vote for the 4 holes. Takes a little longer, but I think the fitment is better.

05XD, what header did you have? Just curious, and this was on the XD right?

As far as long-tube headers go, I've seen them usually referred to the ones that have all 4 pipes lead under the oil pan and collect at one point to continue on to the cat.

I had one of the first SSA headers made for the 97-01 Tibs.4-1 shorty style header and I had it on my xd and gk

Would the SR 4-1 be considered a long tube? The collector is way down there. Also, has anyone used the SR headers, and if so, how have they held up?

Thanks a lot guys.
