headers help
 

I once read somewhere on here...cant find it anymore sorry...that there are some headers that give u a cel and some that don't. i finally saved up the money to purchase one of these fine pieces of metal...but not sure which one.

If you get a spacer, then you will not get a CEL.

yea.. you need to get something to cover the 02 sensor.. many vendors who sell headers will sell that piece to you at an additional cost.

of course, the best way to prevent a CEL and maximize the true output from a header is with a tune. otherwise... a header may just be a waste of money

we.... maybe not a waste of money.. you will get cool sound but not nearly the amount of power that you will with a tune

thanks so the borla would be just fine then..

unichip is good enuff of a tune for me, thanks for the info tho

CELs come from your ECU letting you know that hey something is abnormal. Adding a spacer or a defouler is only a temporary fix to fool the system in thinking things are still the way they used to be before you modified it. Your best bet to have no CEL is to tune the vehicle to let it know that your current amount of flow is normal.

How about just buying the TRD exhaust, then you are guaranteed no problems.

I'd wait for the nameless headers bro

That's not a header.

im wondering if my unichip with fix that? btw who has the biggest headers maybe ill buy from u

because u don't get cel from ur exhaust

all the ones im finding are too small

It sounds like you have the money and need to now take some time, be patient, ask questions and do some research.

Lol. Is that what im doing? Whats ur opinion? I was looking at the borla set up but after final finding the size. It seems kinda small. I will be going s/c one day so I wabt one thatll b big enuff

Unichip will not do anything for a component it doesn't connect to. It changes the values that the ECU sees, it doesn't modify the programming of the ECU in any way. Unichip doesn't connect to the O2 sensor, there's no way to fix that issue with it.

Additionally, for Unichip to perform at its best (not accounting for stars aligning) you need a map designed for the mods you have. I haven't looked for myself, yet, since I already have the maps I want, but you should do some research to see if the mods you're doing fit well with that solution (unless you are or plan to hire a Unichip tuner).

I think you need to do a lot more research with your choices on aftermarket parts. Check out the FI thread. There's plenty of people running headers that are just fine size wise and producing great numbers with the vortech kit and the innovate kit. Pick one you like, research it, and buy it if you want. You aren't going to find many large headers because this is only a 2.0L engine. Exhaust on the other hand, you'll find up to 3".

I would say to go with Borla at least for now. Here's why:

•They're pretty cheap.
•They're the lightest headers available right now.
•You can sell them later when you go FI if someone releases some really good S/C-supporting headers.

Lots of people talk shit about the Borla headers, but most of it is just that a few people had problems (there was indeed an early batch that was bad) so everyone else thinks all Borla headers are garbage and spread that attitude around the forums like fire. You'll also find lots of comparisons between the quality of welds on the Borlas vs pretty much every other set. Yes, the Borlas have probably the worst looking welds on the market, but I have yet to hear of someone having cracked welds.

I'm hoping in the future someone will release some obtainable high quality titanium headers. Until then, I went with a used set of Borla headers. Three hunnah bucks. When/if the time ever comes to upgrade, I can probably sell them for what I paid for them or at least really close to it. If you want headers NOW but are concerned with diameter for a future FI build, my recommendation is to do the same thing I am: cheapos for now, upgrade later.

But as it's already been mentioned, I think you'll be fine with just about any set in regards to their diameter restricting air flow behind a supercharger.

If weight is a concern for you, and it should be if you care at all about performance, here are some numbers to make your decision even more complicated: http://www.ft86club.com/forums/showthread.php?t=42555
You're welcome.

Ok, i have a question i am about to buy a header (inclined in the borla) but i dont want to go cat less) is there any header out there, were i can keep the cat? And i can just put a high flow one?? Or should i just not get the header and buy the high flow cat instead?? My set up is a Greddy evo 3 exhaust and blitz cold air intake

You'll have to get headers that have high flow cats in them. I've always wanted to go catless though, so I don't know what your options are. You can also get front pipes with high flow cats. If you're trying to comply with emissions requirements, then I don't know how many you'll need to keep within regulations.

The only catted UEL option I know of is FA20club's. It's more geared for in preparation for turbo later the way it wraps around in front.

Thanks, so should i go for that header? Ir just get the high flow cat?

Why do you want to keep the Cat? FL has no inspection. (Boricua here too).

Get a tune with the header. It's well worth it.

You'll still keep the frontpipe Cat.

2 reasons: 1) im military always on the move
2) i dont want to have to deal with the check eng light

A tune should cure up the CEL and any intake/exhaust upgrades without a tune is just silly anyway.

Aight, so what header should i get then? (Im thinking borla uel)
And does anybody kno a good tune place on clearwater area?

Well, I can understand if you are on the move wanting to keep the Cat.

About the tune, get a remote tune for it. FA20club here in south FL can take care of you.

Borla or FA20 header as mentioned, my preference and what I'll go for is the fa20 simply cause it caters to both NA & FI applications by its design. Don't forget companies like Avo Turboworld make 5" high flow catted front pipes so you can go with an un catted header with that option in mind as well as their front pipe also has a bung for your O2 sensor on the front pipe.

And as sports guy mentions you're in the right state, fa20 is right there, give em a call they have everything you need to get pimped out. Hell if I lived where you are, it's honestly a NO BRAINER. :)

I'd go catless. First off, catted is more expensive on the header. Two, more likely to fail quicker than a front pipe cat due to the high flow through the header.

Like he said, keep the cat in the front pipe and call it a day. Unless emissions requires you to have two, I see no real reason, but if you're already looking at an aftermarket header, emissions is out of the question, catted or not. 99% of them all say "off-road use only"

I should have my JDL UEL Header very soon. I am Vortech Supercharged. As far as build quality JDL rocks. One thing I like is that they have the flex joints to allow for heat expansion. I also like the collector and the welds.

If I did not order the JDL UEL I would wait for Nameless Performance to release their header.

Oh i should prolly note my car is AT

I don't think that would affect anything.

Same boat as him. Nameless and JDL are two extremely high quality headers. Nameless should be releasing theirs soon. I know soon has been used a lot with them, but they are busting their ass now to get it out to us.

I personally went with JDL and I'm waiting on it to be chrome thermal coated. I wanted the UEL sound because exhaust note is big with me.

Every header thread I've seen has had at least one person say wait for the Nameless headers. I'm not familiar with them, but I'm guessing they're known in the Subaru community. If they don't add at least 100hp, are completely weightless, and sound like Jesus taking a shit, I'm going to be terribly disappointed.

It's because of the way they produce their parts. They don't release crap. They thoroughly test things, and if it takes several months (In the header's case, over a year) they wait it out till its right where they want it. There's a reason Road & Track has their exhaust in it.

They have maps for headers thats why I ask if idll solve to upgrade/cel issue

Kk thanks I never really thought bout that but I see now

U are awesome

Until this morning, I had not thought that Jesus taking a shit was pure awesome, I feel great now I learned something and it is not even noon yet! LOL! :bellyroll:

There is a limited amount of storage in my brain, and it is full. When I'm presented with new information, I have to decide whether to forget something in order to make room, or never learn the new information. So I'm prioritizing all the time. Consequently, my brain is full of only the most important of facts, as you're beginning to learn.

Well some of the funniest shit i've read non less. That said thanks and I bid you all a good day! I actually may need to quote that in my sig it was that funny and original. :D
