im in the market for purchasing a header and a bbtb.....

my 1st problem with the header.....i dont know which one to purchase!
i have the evo fusion cat back exauhst so i was going to purchase the evo fusion header.....but this header eliminates BOTH cats!
in ILLINOIS the new emissions standards....all they test is the OBD to make sure there is no CEL
so i can get away with no cats....and i know a machine shop that will make holes to mount my 02 sensors!

but how ****ing loud will it be with no cats and the full cat back exauhst?
also this header wont be available till march!

does anyone recomend a header that keeps the 2nd cat? perferably a 4-2-1
also i would like if it had the hole for the 02 sensor already there!

and it has to be direct bolt on!

2nd questions....
will anyone recomend a BBTB at a decent price?
perferablly 58mm and up

Hotshot is the header to go with if you want to retain the 2nd cat and no get a cel. Unless you have an 02 sensor sim the Evofusion will not pass emmisions even if you relocate the 02sensor as there is no cat.

[Havro]

what is an o2 sensor sim?
and where can i find the hotshot header?
and the hotshot header has a place to put the first o2 sensor?

[FordFasteRR]

you can reset the ecu just at the entrance to the dmv test and that will rid you of the CEL during the test. :)

[2GTS]

Check the NT.com boards for sellers of the hotshots. They are completly bolt up, no drilling welding nothing, and they come with a kit to extend the 2nd 02 sensor. An 02 sensor sim is a dealie that you wire into the 02 sensor that tricks the computer to think you have both cats and your exhaust has been cleaned between the 1st and 2nd sensor.

[Havro]

now when the o2 sensor is extended.....doesnt it mess with the computer....because the cat is missing....

[tharptroy]

if you can hold your horses(thats texan for wait a little while) on the BBTB, I can probably round one up for you. my prototype is finished, its just ugly. do you have cruise control or no?

Im waiting on a new tool to bore them out so it wont be so labor intensive, and have found a place locally who can laser cut the plates.

im biased to the hotshot, but if I were you, I might look into the forza header that the guy that ran a 15.2 has.

[Havro]

15.2 with just a header? lol SOLD!

also im gonna wait on the BBTB.. and yes i do have cruise control but i dont use it!

ok i was looking at the hotshot header.....

http://www.hotshot.com/hotshotheaders/hy3022.html

is that hole on the far right pipe the place for the 1st o2 sensor???
just wondering how that can get a accurate reading...

because if that is where they mount it at...im just gonna buy the OBX headers off ebay and i have a shop that can do that for free!
cause i dont wanna spend almost 400 for headers!
the ones on ebay are 150ish

i was only gonna use the 1st part of the OBX header....but if i used the test pipe also (the test pipe has location for 1 o2 sensor)
and if i got the other o2 sensor fitted in the 1st header part....would i throw a CEL?

both o2 sensors will be in place....but no cats at all?

[tharptroy]

I bought an OBX header before, and if you really want to see good things out of it, you will have to cut it apart at the merges, port it, then weld it back together. no cats does equal CEL, you will need to place the 2nd o2 sensor after a cat, otherwise you will throw a code.

[Havro]

so the obx sucks?
i just dont want to spend 400 dollars on headers!
so the only way to not throw a cel is to leave your 2nd cat on and put both o2 sensors after that cat?

but that doesnt seem right....if u look under your hood...our 1st o2 sensor is BEFORE the 1st cat!
and the 2nd o2 sensor is after the 2nd cat
so they are getting a before and after reading!
which means u can put that 1st o2 sensor anywhere on the header because it is getting a reading before the exauhst goes through a cat!

[slvrsleeper]

If at first you don't succeed search, search again... This poor topic has been beaten into messy fragments on these boards over the past year. You will throw a CEL adding headers of any brand at least once, You will have to add a catalytic converter if you want to sleep at night in an emissions testing state, and you will end up spending the extra dough you are hoping to avoid if you start with the cheap alternative. These are the facts as I see them and using my own personal experience on the subject, let the opinions fly.....

[Havro]

i have been searching and reading alot....
just asking questions along the way!

[2GTS]

Yes obx/ssa suck ***. As far as a cell goes to avoid it you must have a 02 sensor before the cat and another after the cat. Hotshot's setup gives you everything you need to not throw a cel. The Hotshot header only replaces the 1st cat, leaving the second cat inplace. Install the 1st 02 sensor in the header and then install the 2nd 02 sensor after the remaining cat(you will need a bung welded in). Stop thinking about the money, seriously. You buy cheap stuff you get bad quality. Save the extras from another pay check or two and get the hotshot header. You will not be dissapointed.

[Cyberz XD]

so do you guys think that if i were to do this to the GT on kspec from the Tibby you think it will work also because i want to put some headers but i don't know which on to go with and i don't want to have a CEL if i need to have both sencers on.

[ilanpro]

You can keep the second cat with the evofusion one just dont use the test pipe, if you have an 04-05 the manifold and second cat pipe sections are different, then you have to use the test pipe, or add the cat. but for the 01-03 is a direct bolt on to the second cat pipe.

[Havro]

i think im just gonna go with the hotshot....
ceramic coated....no cel issues
ill just dish out the cash and get it!

i have the evo fusion catback.....
with the header installed can i expect the exauhst to be louder or no?

oh yeah much louder

[Cyberz XD]

Can you guys tell me what type of Headers i can get to were i don't have to get a Second O2 welded on and just have a header that both O2 sencers

[2GTS]

None.............

[billydog]

will you get a cel with the 1.8l header from the older elantras and tibs?

Thank you Ilan! I have been looking for this answer for the longest time....perhaps I will install my headers soon since I can bolt it up to the 2nd cat and not throw a CEL..right?

EDIT: I have the TeamSR ones.

[2GTS]

YOU HAVE TO RELOCATE THE 2ND 02 SENSOR AFTER THE 2ND CAT TO NOT GET A CEL! IS THAT CLEAR ENOUGH FOR YOU? YES I AM YELLING AT YOU BECAUSE THIS HAS BEEN BEATEN TO DEATH AND COVERED IN ABOUT 20 DIFFERENT THREADS.
You have to have a cat between the 02 sensors to not get a cel. Now do you understand?

[Choking Hazard]

ALRIGHT 2GTS! I WILL YELL BACK. ISNT THERE AN O2 SENSOR THERE ALREADY? WELDING IS NOT A PROBLEM FOR ME I WAS JUST CLEARING SOMETHING UP. SORRY I AM NOT A MASTER HYUNDAI MECHANIC LIKE YOU! heheheheh Done yelling now :D
