AMK Racing Header

[eii]

So I bought the AMK racing header from ebay that was posted in this thread.(http://www.yarisworld.com/forums/showthread.php?t=16119). So I torqued and re-torqued the whole thing, used the gasket that was included which looked fine and made sure the collector end of the headers were securely attached to the mid pipe.

It sounds like crap to me...is this normal? Thee noise is like how stock engine idle is, but super annoying. I tried everything I could to address any leak issues. There were no included hardware such as different bolts included so i used the stock ones. Is it really just suppose to be this loud? I read people saying it doesnt make much of a difference in sound. I cant stand how loud this thing is, it sounds like some junkyard beater. Lemme know if this is normal, otherwise its gone by tomorrow.

i have the dc and it didn't sound that much different from stock. can you describe wat sound you are hearing?

[PHXDEMON]

Sorry to hear that. I think with headers it is a hit or miss if it will make your car sound like crap. Probably just a poorly designed header. Do you have any other exhaust work done (midpipe/axleback)?

[eii]

I dunno, it almost sounds like I have no muffler. I really dont know how much more I could torque every bolt up till the heads fly off. Bleh, first mod to go wrong on my car :'(

I got a TRD axel back, its not very loud by itself.

I have a feeling it might have to do with the collector part of the header...maybe..

Sounds good in park till i put it in drive or reverse.

[PHXDEMON]

Does it sound crappy or is it just too loud? Could you possible upload a video to youtube?

[PETERPOOP]

$69 dollar header.....

[eii]

$69 dollar header.....

lol yeah i know, but i said i would test it for everyone. :laugh:

[PHXDEMON]

Sell the header to me for 20 bucks and I'll just weld a 45 onto it and dump my exhaust right behind my front wheel :laugh: Shoot flames out the side n shit :bow:

[PHXDEMON]

lol yeah i know, but i said i would test it for everyone. :laugh:

Thanks for testing it for us :laugh::thumbsup:

[eii]

Thanks for testing it for us :laugh::thumbsup:

I took one for the team yo! Seriously though I'm glad I cleared this up for everyone and could contribute.

I put stock back on and its back to normal loveley cai and trd sound. I spent the last 7 hours working on this thing, im soooooo beat. I'm going to be sore tomorrow :frown:. Well I can only assume there was a leak, possibly the gasket or somewhere in the welds, but I couldnt see. I know something was wrong cause the headers came out a different color than before, dunno if thats from something else though...:eek::laugh::bellyroll::bellyroll:.

Well this will probably be the last engine performance mod I'll do for a very very very very long time. I just put in a nst lite crank pulley and the 1zz tb earlier this week with no problems so that'll keep me going till the physical and mental trauma from this wears off.

I have video and pix of this header, but my SD card reader is in my car and I want to stay as far away as possible from my yaryar right now. Too frustrated and tired :laugh:.

Ya so now I dont know what to do with this now...;)

Peace, thanks for checking my thread out :bow:

[Nexus1155]

Ummmm did you just get a gasket for the midpipe, or for the header to the engine itself.... It's a header, made from piping, and it expels the exhaust, its resonance and sound should NOT sound as bad as you said, somethings wrong

[Sabretooth]

Did you get a new gasket with it, or the flange that go between the midpipe and header outlet?

If you didnt, its Very possible that there was something wrong with the collector(bad weld).

I proved it a long time ago that Megan outsources their headers, and the ones that they dont like they resell...Those get sold as Ebay knockoffs. Time to redo that post

[Nexus1155]

assuming it was a pre hack post like all of my good ones too hahah

[severous01]

i had probs with cheap headers before. the first thing i do is take it to someone with a big disc sander and have them flatten the mating surface. that's stopped 2 leaks for my camaro.

second would be to completely inspect the holes and mounting points of the header for globs of weld splatter or other interferance/mounting issues (this has been an issue twice as well for cheaper headers.)

[Sabretooth]

Well the worst that hapens, if the header blows up. Pray it doesnt hurt anything else then go buy the real deal.

IF my Megan Racing header croaks on me, I am going to get the DC Header (Althought no one as of yet has had to replace their Megan header due to malfunction.)

[YarisSedan]

Yeah what you are describing is probally a exhaust leak. LIke a annoying constant farting sound comming from the engine at idle

[cali yaris]

Your megan header should last a good long time - it's well-made.

DC Sports was acquired by another company and is not currently producing a header for the Yaris.

[Sabretooth]

Good to know about DC not making anymore headers for us, Thanks Garm.

[eii]

Thanks for the response. I added a quick video and pics to my first post. The video is really quick, but gives you an idea of what it sounded like. It was really loud over only 1.5k rpms :(. It was more like a farting noise like yarissedan mentioned. It was soooo much louder than the stock header. Not sure if you can get a good idea from that video.

[Deltasix]

I have the TRD Axle Back, so I have a good idea what its supposed to sound like.....

...and that sounds like crap!

[RagnaCaT]

So it's impossible to get a DC?

[PHXDEMON]

You could maybe get a used one :iono: Good luck finding it.

Yeah, this is a short video of only my TRD axel back for comparison

BTW in the header video the high rev at start up was because of the 1zz tb. I disconnected the battery while I was installing the headers so the ECU had to re-recognize the 1zz tb. The middle of the clip is when I put the car in drive, then park again, and then off (thank god :laugh:).

[jouna]

i don't know what's all the fuzz about this header cuz i said i had it and it sounds like a normal header and it haves noticeable gains maybe your header came faulty but mine works fine and its the same amk header

[cleong]

Plug one end, fill it with water from the other end, spot where its leaking water, get it welded shut?

Oh and did you prise the bung off the stock header because you didn't mention doing that? Its a conical ring around the exit of the header, you need to bring that over to the new header.

Good luck!

[PHXDEMON]

Yeah I think he has an axhaust leak somewhere :iono:

[MANSETH]

Normally, when we change header, sensor will read different CO2 from new header. It could make the ECU calculate different O2 and CO2 for a while.
Means ECU malfunction, take your car for a one day drive then it should back to normal then depends on how good the header is. If your header was not leak.

[808_Yaris]

probably poor workmanship on the header? to my knowledge, the welds
could be a LOT better.

[eric81]

I have the same header on mine, and it is loud as hell. I noticed gains in power and in how fast my RPM's go up. Less resistance on the engine means it isn't working as hard to do the same stuff. Any header will make your car louder. The farting noise does sound like an issue though.

[eii]

I'll check for leaks later today.

[cleong]

Did you transfer the exhaust pipe gasket off the original header onto the header that you bought?

It looks like this:

OH FCK ME. I knew I forgot something. Is it easy to take the stock one off or should I just buy a new collector gasket/donut?

[808_Yaris]

it's easy to take it off the stock one

[eii]

Ok, well I'll work on this again in a couple days. My hands are still sore/cramped up from the previous attempt to install this. I just came back from autozone and got a 1/2" 12mm deep socket which I was lacking during the installation. This will make things 1.5 million times faster! I was able to remove/install this under an hour and I now know this installation like the back of my hand. Should be easy sailin'

[cleong]

The Yaris Shop Manual states that you should use a new one. However I reused my original gasket with no problems.

[808_Yaris]

From my own experience, either way is fine :thumbup:

[Nagoya_TRD.]

The quality and welds on that header make me want to punch a baby.

[BLAZINBLUEVITZ]

The quality and welds on that header make me want to punch a baby.

my newborn says come try it bitch:laugh:

[eii]

I tried putting on the stock exhaust pipe gasket on. The noise isnt so annoying now. I can only hear it when I punch the gas a little. I also smell some burning from the engine. Still a possible leak? I tried filling it with water to check for leaks, but there wasnt any. I'll try again to re-torque to make sure the gasket is fitting ok. Also the noise only happens when I slightly hit the gas. It just sounds like the normal engine sound but louder. When cruising or WOT you cant hear the noise. Maybe it'll go away after driving for a while so the ECU learns the new air flow.

Also the weld on the bung is by a friend, so just in case thats whats making you punch a baby. :laugh:.

[Nagoya_TRD.]

The welds on everything makes me want to punch a baby. Not just the o2 bung. I would rather keep my car stock than run that.

[eii]

I probably will put it back to stock for the 3rd time. I just got CEL and the smell dont seem right. I'm pretty sure theres a leak. Severous is probably right about the mating surface not being flat as I cant find any leaks in the welds or probably something wrong with the gasket. Plus with the cel and the low end torque I gained from the nst pulley is gone which was really nice I'd rather have stock back on. I guess its time to work on my cosmetics.

[eric81]

The welds are bad on ALL those headers. They should have smoothed them out before shipping, but I am sure that would have drove the cost up a bunch. And I couldn't use the stock A/F sensor, since they cross threaded the hell out of it. Anyone else have that issue? That is when I had some serious trouble with mine, and then trouble with the plugs, then the battery, and the list went on for awhile. Now, my car is fully operational, but I was tinkering with it yesterday, and noticed a hose going from where the exhaust cams/ valves are to the intake manifold. When disconnected, the car barely ran, and wouldn't idle at all. What is THAT about? Is there a possible power increase in waiting by replacing that rubber cr@p with a larger, sturdier pipe? Or maybe finding a way to push more air through there or something? I am WAY syked about it, and am going to tinker with it tonight with my neighbor, and see if there are any engine improvements waiting to happen. As we all know, every pony counts when it's stock 105HP and 2,300 lbs, right?

[808_Yaris]

hope everything works out for you eii!

[eric81]

Eii-
Did you get the private message I sent you? If so, did it work? If not, should I just post it publicly here so everyone can read it? Let me know please. Thanks.

Also, what is the G H thing about?

[eii]

I freakin lost one of the 12mm nuts on the back (the ones on the ends) of the header in the engine bay and for the life of me cannot find it. Grr......

[eric81]

Had the same problem... there is a section of frame that goes from middle of car to right next to the tranny. My nut dropped into it and rolled back almost a foot. It was hard to reach, but that's where it was. Try there.

Lol yeah! Thats exactly where it was. I was just underneath my car burshing my hand against that frame hoping I'd finding. I had completely lost all hope after 3 hours trying to find it. Then bam! I felt something move when I brushed my hand over it and it was it! :thumbup:

Well eric, I still got CEL and dont have an OBDII reader so I'm not sure whats up. That burning smell was some stock electrical tape that was hanging and hitting the engine block btw!

[eric81]

Try resetting the engine again... then make sure you have the right A/F sensor in the header, and that it is hooked up properly. I bought a replacement, but it was an O2 sensor, and it messed up my plugs and battery. Other than that, go to Auto Zone, Chucks, or a tuner, and ask them to read your CEL for free (most will, especially if you explain that you're tuning a rare car) and see what it says. I had mine read at 2 different places. I got the message Engine Heater Coil, or something like that, and that was the stupid A/F sensor. Did you crank the hack out of it when you put it in? Hope these tips work... and good luck.

[eii]

Ok so I wanted more power from my lil yaris so I decided wtf, I'm going to put this header back on. Success! I unplugged the battery before running the car with the header and made sure the gaskets were on properly. I've been running it for a couple days (really really hard at some points) and have not gotten a CEL. Heres a sound clip of it with my other mods (in my signature).

Direct Link: http://www.inimi.org/downloads/eiiexhaust.avi
YouTube Link: http://www.youtube.com/watch?v=rgQiuWupPgw

So I hang out with a lot of Honda folk, DAs, DBs, EGs, EKs, etc to the far as you can see. I've let them drive my car before the headers with my other mods and they were impressed with the "pickup" my car had. A major compliment considering I have to take so much from them being honda fanatics and me owning a Yaris xD. I put these headers in and they love the sound and when they tried driving it this time the first words that came to their minds was "TORQUE-Y!"

I gained a lot of torque through out the rpm range, waaaaaaaaaaaaay more than I had expect. The sound is pretty nuts to if you havent checked out the sound clip. Wow, just wow...

[1NZYaris1]

So your $69.00 header is all good now .
did you replace any of the gaskets :iono:

anyway congrates on getting it sorted :thumbsup:

I'm using stock gaskets. I just have a feeling the stock gasket at the collector doesnt work 100% on the aftermarket header, well for this ebay one that is. The gasket is working though, I had it without the gasket on the aftermarket header and it just sounded terrible. I mean its possible that its normal for the engine to be this loud with an aftermarket header. I need to get with one of the members here in socal who has or has had a header and see if they are experience the same noise.

[llimonce]

you have the bolts with springs in the exit of the header ?? i think is necessary maintain the springs

[eii]

Yeah, I used the stock bolts and springs. I've gotten very used to the extra engine noise and it seems normal to me now. I got bigger problems now, got into an accident and now my frame is messed up in the front :'(.........................
