I just installed my new headers today (my gf bought for my birthday) and it took about 5 hours...All in all it was totally worth it. There is a huge difference in the way it sounds (much louder now) and I do notice an increase in HP.


>>Before Header>>


>>New Header Not installed>>


>>Header on car>>

you should wrap it, it will discolor in a few days, and are you missing a bolt on the right side?

wheres your new gasket too?

looks good, where did she get them?

Bolt was already missing when i took off the stock ones. They were actually studs with nuts on the ends so i wasnt sure about replacing it...

I did replace the gasket, both the top one and the bottom one.

you can get a new stud from the dealer for about $2 and the nut is about $1. Splurge and get them

looks just like mine

k-weaver your header pic is on eBay lol. Did you send in your pics to the company?

get a new stud for sure, or you can have an exhaust leak

How much?

Notice any difference with it? HP? Noise?

I'd only really want one of these for the looks and wouldn't want to wrap it, but I assume it's going to discolor badly regardless right? Can these really give that much HP gain?

Yeah i will go down to the dealer for sure and get those parts, thanks for the input on that...

I got these on ebay, the guy i purchased them from just so happens to have the same set up as me in the pic, the pic on ebay is not my car...

I got these for 95+40 shipping. The only problem was the bottom 3 bolts that he sent did not fit into the stock pipeing.

I did notice a HUGE difference in sound, car is much louder now. As for horse power, i noticed an increase. It seems to pick up faster now.

I was considering wraping them, only becuase they get really hot. I read about some wraps and they say that they can reduce the heat. This true???

That looks like california spec, because of the holes for two probes. I'm interested in one for my california GT, where exactly did you get it? (I know ebay, but what seller)

bump, i wanna know too

Still waiting as well, is this the guy who sold it to your gf ? http://cgi.ebay.com/ebaymotors/Toyota-Celi...1QQcmdZViewItem

haha , you posted the link to the header i bought. good seller so far, he gave me a tracking number for the shipping. ill post pics of it and let everyone know how it sounds and performance when i get it installed.

did you install yourself? or is it best to just take it to a shop

its not that bad to install yourself, just make sure you give yourself plenty of time, pick a morning, pick up some bolts, washers, lock washers, and nuts. i believe i got the 2.5" long bolts...another thing is buy a new exhuast gasket and hi temp gold sillicone..make sure you seal it really good around the downpipe to the exhaust...im not sure if that seller gives you a new manifold gasket either...that can be bought for 15-20 bucks as well. taking off your stock manifold ist that hard, just dont strip any studs. make sure car is cold...touching hot parts hurts. and i recommend wrapping the header because it gets very hot. throttle response is okay, in the begginning your car will sound weird (farty-raspy), that goes away in a week or so. it will make your car louder so be prepared to get looks.

does anyone know about how big a diff putting a new header on would make HP wise? other than it getting hot is there any other benefit of wrapping it?
i'm kinda thinking of getting one but not sure if it's worth it. especially if i am planning on a swap in a year or 2.
also would this work on say...a beams? probably not but it's worth asking

yeah i finally got mine in the mail yesterday and i got it instale already. according to my ass dyno i think its definately good for 5hp minimum. the bolts that were supplied with the header are too big, but just get some smaller ones and call it good. the o2 sensor is a little tight getting on but it went. it was almost a little tricky getting the manifold on but it was just a matter of how you hold it to put it on. i would advise to loosen the alternator to make for just a bit more room to work. as for the sound it does sound a bit raspy but i love it. its louder than before and it gave my engine with almost 300,000 miles, a little bit more ummph. i do get a few more looks with the loudness but its all good.

To guys saying it makes the car louder, do you also have upgraded exhaust? I wonder how much louder it would be if you just had stock exhaust.

-Matt

yeah my car has stock exhaust other than the muffler. its a rative muffler.

after you guys install new headers do you re-install your heatshield? or do you just wrap the pipes, or both?

i would probably go heat shield and wraps if not just for the fact to make it look stock.

you wont be able to fit the stock heat shield back on... easily.
Wrapping them is the way to go : )

after looking at the pictures again i was beginning to think so. thanks for the clarification though.

Yeah, it would be nice to be able to fit the heat shield back on as for daily-driving protection and for shows take it off and show them pipes.

So, did the girlfriend get some major brownie-points for this buy?

did everything went in okay?...like did everything bolted on easily?.....i really dont wanan take this to a muffler shop to have it welded on to the cat......

Nice job on the install. I also saw this on E-Bay.
I'm interested in one but do you know if this is smog legal? I live in a state that requires emissions check.
I see the header has ports for O2 but is there not a pre-cat on the OEM manifold?!

Thanks

no headers are smog legal that ive seen

Yes, you are right, so I'll reword my question to k-weaver.

Does your Toy pass emmisions? I see there are ports for the O2 & EGR.
My concern is that the pre-cat is removed with the stock ex manifold, therefore would not pass emmisions?!
Any comments or does any body else have a 5sfe w/headers and know about emmisions?

My 4Runner has headers and it passes, but it doesn't have a pre-cat.

I ordered one of these Ebay headers and it has been received. Due to my perfectionist nature, I had PMed a few of the people that have installed this header (including k weaver) b/c I was worried that the bolt holes on the header looked off, and not centered with the surrounding metal design. So, although I have not installed it yet, I have concluded that I should not worry. So I spent a couple hours under the hood, and found the manifold studs anchored to the block are 10 mm wide, while the holes that the studs go through on the header are like 14 mm! That should definitely leave some tolerance if your holes look like they off kilter when you receive your header.

Also, in reference to the first big, O2 sensor, with the oval shape and attached by the two studs...well the hole on the header is not perfectly center between the two studs that the O2 sensor attaches on. After studying the stock set up, this is how it is anyways...there is about an 1/8" difference from middle of the sensor to one stud, and from the middle of the sensor to the other stud.

These are just some preliminary observations before I actually install this very inexpensive header...but the quality seems to be pretty good. If I run into any other issues or find any other technical info to share, I will do that. And pics to be added once it is installed.

>>One question: Should I expect any CEL code to be thrown, or will everything be okay as long as both sensors are plugged in?

My impression is that although we are removing the pre-cat, it really only "covers" for the main cat under the car until it warms up and starts doing its job. So without the pre-cat, we are really only throwing unnecessary pollutants out for a little bit of time after starting the car. Let me know if I am off base.>>

it shouldn't throw a CEL. I have the cali emissions engine and I couldnt get one of the 02's out of the old manifold, so I used the plug (that conveniently came with the header) and screwed it in the hole.


no CEL light for the missing sensor
