Best Header?

[chongopants]

I was wondering if anyone has done a side by side comparison of all the major brand of headers. Like a before and after... I would like to know which will give me the best performance before I buy em. Also I noticed a lot dont come with gaskets, I find this VERY annoying b/c I dont reuse gaskets. So little things like that which will help in the decision making process. Any info is welcome!:w00t:

So far:
Megan Racing
DC Sports
AMK
Thunder Street
ANY MORE? Lemme know I'll start a poll...

[hatchbackkid82]

Dc Sports....no other one even compares

[hatchbackkid82]

Installed mine with out a hitch. Everything bolted up perfectly. Had more problems getting the O2 sensor off the stock manifold

[chongopants]

Good to know, I am leaning towards the DC even though it is more expensive, but I have seen in several threads that the bracket doesn't line up properly... any idea what they mean?

save your money for things that will actually make your car faster ;)

[chongopants]

well everything I have read says that a good header does make a difference... do you have proof otherwise...remember your on a modders forum...

[hatchbackkid82]

So what he is saying is just save up your money for a SC that cost $3400 or get a custom turbo kit made. I'd rather spend $260 on a header. Keep in my mind though that no matter how many bolt on's you throw on this motor it will never break 130whp. I have an intake, header, mid pipe, axle back, nst pullies. This was an improvement over stock, i'm personally not ready to just drop that much money at once on a mod, If you have the cash for it then great go for it. But the header is a great mod i say go for it:thumbsup: there are a lot of members on here that have it and are very happy with it, me being one of them.

Remember you pay for what you get. don't go cheap on parts you'll pay for it in the long run

stock.

show me dyno sheets of before/after the header

[hatchbackkid82]

I say get it:thumbsup: don't let the naysayer's on here get to you. The header does make a difference, of course keep in mind that it won't be 15hp-20hp, more like 1hp-4hp, it all adds up though if you're going to be doing other mods to the car.

Show me a free dyno... game, set, match...

I will get a performace gain from it I am sure, it wont be huge. But I am not ready to put a $4,000.00 Turbo or S/C on a $10,000.00 (new) car... Just not sure it is even worth it yet. I have a turbo sitting in my living room right now.. Also not to mention, this is my only vehicle and putting that kind of strain on the engine will require severe mainentance over the long haul. I put about 40k/yr in miles on my car... So i am looking for a happy medium for now thus NAS... Thanks for the input, but this is not the S/C or Turbo VS NAS thread. It is the header thread...

[hatchbackkid82]

:clap:

If you do the header you may want to consider getting the Nitto MP and an axle back to compliment the header. Sounds great, and every once in a while it pops:biggrin:

what about the CEL, will the midpipe mess with the o2 sensors? I dont want it to run to rich or lean.

[hatchbackkid82]

Well I tried to just put my O2 sensor back on there with no anti fouler, and sure enough after driving a few miles i got CEL, I bought the anti fouler from Garm and haven't had any CEL. I've been CEL free for 6 months now. When you take an OBD2 car in for emmissions they just plug it up to the OBD2 port no tail pipe test.

BAM!!!!! Ask and you shall receive:biggrin:

[chongopants]

yeah they are on my list for when i get any exhaust work, thanks. So if I got a header and axle back it would be fine until I can get the midpip right? I have never had a car with midpipe, I always had 3" stainless from block to wheels, lol no cat, no smog, nadda... but you can do that on a carb V8...

[hatchbackkid82]

Yeah you should be good if you do the header and axle back. The cat is welded to the stock mid pipe, so if you leave that alone you should still be a law abiding citizen, unlike me:burnrubber:

[chongopants]

I dont care about that so much, I am in TX after all.. But removing the cat has long term implicattions on your engine, and can throw CELs so I dont plan on doing it. I will just get a high flow cat.

[fmicle]

well everything I have read says that a good header does make a difference... do you have proof otherwise...remember your on a modders forum...

The header alone won't make a big difference, since the stock intake and exhaust are so restrictive, but the general wisdom is that if you get all these mods, together they will give you a better improvement than each one of them counted separately.

As for the bracket misalignment, it happened to me. The header is attached to the engine block with at least 4 bolts (if not 6, can't remember exactly) and 2 spring bolts to the exhaust pipe, so it's definitely not going anywhere. I don't think it really needs the extra support the bracket will give it, that's why I didn't worry much about it.

There is a removable steel bracket (painted black in my car) that's attached to the engine and then there is a smaller bracket welded onto the header end. If this weld isn't perfect, as in if it's off my 1 mm, the holes won't align perfectly and the stock bolt won't fit, since it has to be threaded into the DC bracket. That's what happened to me, so I took a smaller bolt and nut and just fastened it like that. Ghetto-licious :wink:

[chongopants]

ok kewl, but if you dont have a rollstopper wont the rocking(of engine) eventually strain the metal in the header?

[Tamago]

you'll have $1000 in 7whp..

i don't get it.

[cali yaris]

megan header + midpipe + Nitto exhaust is +/- $650 shipped.

Doesn't have to be $1000, that's just adding up the more expensive products to get the highest number.

[hatchbackkid82]

Yeah but he won't have to worry about the issues that come with boosting a car, spun rod bearings, connecting rods, tunning, fuel delivery.Not
only that sounds like th OP doesn't wan to drop $2K-$3.5K at once. I don't blame him that would hurt my pockets too. FI would give him the most gain for the money but intially it's a large investment. It all depends on what he's looking for if he just wants a lil' more power than stock i say to keep it NA and just do the exhaust mods. Some people can say the same thing about SC or TBing the yaris $3400 on FI yaris to not even be able to break 180whp:iono:

and the average YW user is afraid of wrenches and dirt, so they'll pay someone a couple hundred to install above parts.. so let's say $850..

i was off by $150.

you can put it in your piggy bank for when your chinese welds start to break on the cheapest exhaust you could get your hands on

you hit the nail on the head. no one should be spending that kind of money to make their yaris ALMOST as fast as a bone stock camry V6.. so why spend $650 (thanks for the shameless plug, garm lol) to make the car almost as fast as a bone stock corolla?

don't forget, i'm speaking from experience here, i've gone down that road.

[chongopants]

well I enjoy modding the car its fun, and after I have removed a lot of weight from the car, and modded the intake slieghtly i see a huge difference. The car can handle very well with a small amt of mods to suspension. In other words its just plain fun... I have a turbo but I am not doing that immediately, and I wanna be the fastest yaris in tx that is kinda street legal... :P

[cali yaris]

ugh -- do what you want chongo, it's your car and if you're enjoying it, that's what matters.

[fmicle]

I hear you man, but come on, does most of the stuff happening in Yaris World's members' garages make any sense? Do I really need an $800 racing seat that hurts my back after 15 minutes? :smile:

I already spent $1,000 on stuff that could also get me a ticket on top of everything, so how does that make any sense? It doesn't, it's a hobby and I like it :smile:

[PETERPOOP]

i'll say megan, just because i own one. lol. a little biased..

[hatchbackkid82]

I know you're speaking from experience, someone could have told you the same thing when you boosted your car. So why did you do it? I'll tell you why cause it's a hobby. Let the OP figure things out for himself. Like someone mentioned on here it's a hobby, have fun with it. I know am :thumbsup:

[redglare45]

I would go for Megan, but same as Peter, I'm a little biased because I have that one :biggrin:

[tk-421]

@OP: You forgot to include the Weapon*R 4-2-1 header... I'm still deciding that one and the DC Sports...
I probably won't be getting a header until I can get a full exhaust done locally though... No point in getting a header until I take out all the restrictive stuff first.

[curik]

+1 on Weapon R header. I like the 4-2-1 configuration. Even with stock muffler, the sound gets throatier and definitely gains power from 2000 rpm.

[RacerFreakXXX]

I think what tamango is saying is that you are petter off saving the 1k for a big mod like turbo. I think it's a persons decision, if you like slowly modding your car then doing that is the best way. You are better off buying good parts in the long run, however I've seen ebay headers last years, lol. A light weigh ceramic coated header like the DC one is gonna be the best out there for the yaris unless you custom builld one for more money, a lot more.

First decide what you want to do with your car and then do it. I'm not buying any of those simple mods because I'm going turbo and it's a waste to buy all the stuff I will just have to resell.

[thebarber]

megan dyno didnt show anything but loss before 5000rpm...and stock #'s 5000-redline

[PETERPOOP]

my supercharger will compensates that...

[TheSilkySmooth]

The car has a pretty good st-steel header on it stock. The power is in the exhaust. High flow cats + 2" > 2-1/4" pipes. Larger is badder**. Go local to a good race shop. I'm lucky, I have 3 speed ways and 1 dragstrip near by so there are a lot of backwoods roundy-round race shops that do stuff for cheaper than China Import Commie Garbage.

I wish I had dyno'd with each part individually. I got 17 whp increase with intake, header, axle-back exhaust and crank pulley.

SO, if the header was a zero, those other mods sure paid off. :iono:

[TheSilkySmooth]

Hey, it adds up exponentially! (whoa, that doesnt make math sense - but it may be a good geek math joke). In other words, It's MORE than the sum of the individual parts. The mods feeds off each other like vampire whores.

- NO! not: MODerators!

i bet it does more cumulatively than by itself....was talking w/ peter about that yesterday in the chatbox...

[ozmdd]

I have UD pulley, CAI, and Thunder axle-back exhaust w/ stock exhaust manifold, and am making basically the same 17 whp gain that Garm got off the same mods with a header. It doesn't seem like the header does very much for our engine. If you go with a full custom exhaust, I'd guess you'll see a few more ponies, but I think we're gettign pretty close to the max HP on this engine (NA) without getting into engine internals/ higher compression mods. You're right to think about getting lighter rather than getting more HP.

As other have said, you want to have a good vision for your mods before you start investing. If you only plan to have some fun with the car and keep the budget low, then my route w/ some light wheels/tires and a few suspension mods will probably make you happy. If you really want a serious street/strip machine, then save your $$ and buy a FI setup that will really perform at a much higher level, then beef-up the rest of the car to handle it.

[chongopants]

Yeah I have found that the most important things to me at least are lightening up the car, and suspension. I would like a faster throttle response and a little bit more power but not a crazy amount, and thats it... Very doable in NA I think... As far as FI, I just can't see myself doing it until I get another vehicle and make this one a toy... soon probably...

[hatchbackkid82]

Nice so that's what the mods do now? They delete our posts.... wow looks like it's the mods we should be worried about, and not confrontational people. way to go mods:thumbdown:

Its the most effective way of controlling a populous, remove info dont add... Anyways this is a HEADER thread, if we wanna fight "The Man" I am down for that, I will start us a forum. But bitchin and moanin aint gonna change anything on here... So lets keep it kewl. Seriously if you wanna join my forums for local bs lemme know and I will set it up.

Later guyz

Stop posting off-topic BS and I'll stop deleting it. It's really that simple.
