I got the Megan headers installed last month and had the same metal vibrating noise too. But then I brought it to a shop to see what's up and it turns out that the sound was coming from the heat shield on the downpipe. It wasn't on tight enough, so it was vibrating. Also, that rubber thing that holds the headers was out of place too. Now everything is fine. No vibration and a little bit meaner sound than stock. It does sound a bit louder than stock when idle. Not a bad deal for $200 headers.

 

Yeah parvo, at one point it got so bad I got up under the car to check it out and noticed my heat shield on my cat was rusted thru. It was rattling too. Its been replaced and that rattle is gone. Wish I could say the same about the headers.

Just to set it straight once and for all, I made a .mpg after work with audio. You can plainly hear the noise I am referring to around 2 min 20 sec into the clip.

I will post when I get home. Gotta run to the store.

 

First of all, this is a forum for discussions just like this. Just because a certain person is riding the nuts of Megan (must have vested interest) and doesn't like what others are saying about THEIR experiences with this product, doesn't mean anyone is bitching. These are our opinions and if you don't like it, don't participate in the discussion. I think its wonderful that some tl owners aren't or didn't have any problems with their Megan purchase but others like myself are experiencing major difficulties so shut the fuck up and don't judge because you aren't driving in our vehicles, believe me it is really annoying. Yes, I did all the retorquing THREE times at a professional shop and guess what, IT STILL SOUNDS LIKE When I looked at the website of Megan when purchasing these headers, it said that it fit both the Accord and the TL. I spoke with Calvin and was told that these headers were being test driving by a tl owner with absolutetly no problems what so ever " there all no fitment or resonance issues at all." Since then we know obviously that was a LIE because of the downpipe and resonance issue that still exist. There is absolutely NO justification because we didn't pay Comptech's prices that we should expect poor quality, it is still hard earned money. It would be different if it was advertised that some may have fitment or resonance issues because we are only charging < dollars less than Comptech. And if I did purchase these headers knowing that there might be problems, then that would be on me but this is a different story. It is ridicuous to settle just because you paid less, personally I paid for a product to work properly, period. So, since my purchase with Megan and all the problems that still exist, I am entitled to MY opinion in which I think the product is inferior. So with that I will never buy another Megan product and will definitely would not recommend it to anyone.

 

you know i'm still a little pissed that my hanger was on the wrong side of my downpipe so they couldn't hang the pipe on the stock rubber hanger. i'm gonna see if i can fix that myself this weekend. and my header wrap came today so i'm gearing up for my weekend project.

keep us posted.

 

Okay, here is the trimmed down version of what I'm talking about. Remember that this is from inside the car with windows up. Imagine what it sounds like outside the car.

http://home.comcast.net/~bostrupe/resonance.wmv

 

I was the one that told Calvin there was no problem EXCEPT for slight resonance. I gave him a ride in my car to hear it. Many members are experieicng a hissing sound which a fine but the few that are experiencing the metal to metal rubbing sound is not normal. As I said, its not normal.

Also, most if not all headers are made the same except for an unlucky few. If I dont have a problem and you do, there might be something wrong with your headers, your car or the installation. Lets try to find the problem together. Check all your bolts, esp bushings, and the cat heat shield. If it doesnt take care of the problem, take pictures of the problem and file warranty. I remember you complained about your rattling before and found that it was the heat shield being lose, well it might be lose again, go check it out.

DTLS-you have the right to say whatever you want. And I participated in this discussion to find a solution not to flame. So read before you comment. By the way, I volunteered to do the warranty exhange because Im on this forum and I would like to help members out with something I personally have experience with. I DONT work for megan nor am I hired by Calvin. I dont get a penny for helping members out. You should appreciate what others are doing and start acting your age.

 

Okay, for the last time: ITS NOT THE HEAT SHEILD ON THE CAT! That rattling noise had its own distinct rattle and is gone since now since its been replaced. I do agree that others should check their heat shields though if they already haven't. But in my case it is definitely NOT the heat shield.

And BTW I did and still do appreciate you handling that warranty exchange for us.

 

who here thinks i shouldn't put wrap over the short flexpipe? (not the long one before the cat). also, anyone know how hot the cat gets? i'm curious if the thermal wrap can withstand those temperatures.

SSTS

 

I wouldn't advise putting the wrap on the flex part of the exhaust. Check out this link regarding FAQs.

http://www.thermotec.com/technology/faq/faq.html#q1

 

that answers everything. thanks! i don't think the issue lies in the flex section anyway. i suspect it is more where the downpipe sits next to the oil pan and just around where the hanger is since i don't have anything there to support the hanger.

SSTS

 

Watch your mouth son, and stop accusing people of just bitching or blaming the headers when the headers ARE the problem. Trust me, my reading and comprehension skills are just fine and you seem to take criticism about these headers a little personal which you so blindly stated by being Calvin's test dummy. Remember, it is not about you. You speak volumes in your retort even though you try not to because you and Calvin are buddies and you have no problem with yours. Stop acting like everyone who's having problems are idiots, like we don't have the common sense to trouble shoot like when I HOPED it was my heat sheild and after removing it while troubleshooting, it STILL SOUNDS LIKE SHIT. Instead of running your mouth and getting in way over your head, I suggest you take this information gathered here in our sacred forum to your buddy Calvin and help us SOLVE THE PROBLEM instead of taking criticism about an inanimate object to heart. How's that for acting my age, don't get upset because I see how transparent you are. And since I am so much more mature than you, I have the ability to not hold any childish grudges and let our little flame war end, you stated your stance and I stated mine so drop it.

 

Hey guys, I know you're all disscussing Megan header issues but I thought that I could maybe help out a little. As I've posted before I had a set of Stone headers and later bought the Alphawerks, when I put them side by side I noticed 3 things that stood out (1) the size of the tubing in the Stone was a smaller diameter than the A/W (2) the 02 sensor bung was closer to the flex pipe than the A/W (3) the material used for the flex pipe is much different. I'm going to post pictures late this aft. and maybe the guys that are having problems with the shrilly metalic sound can compare. And just so you know the Stone was installed at a garage by a licenced mechanic, and the Stone was removed and A/W was installed by ME and I have absolutely no problems at all, so to those of you who say its not the header, I'd have to strongly disagree as I've listened to the sound clips and from what I can hear the sound is exactly the same.

Peace, Jeff

 

Calm done DTLS. Flame war wasnt started by me and youre the one that seems to be taking it too personal with flames coming out of your words. I comment a lot on this issue because I dont have problems and I want to know why people are so I can tell my "little buddy." So what if Calvins my friend? That at least made it easier for me to ask him to make a new downpipe that solved problems for some. And no, people are not idiots. I rec people to trouble shoot because THEY DID NOT INSTALL THE HEADERS, therefore, they never looked at the surroundings for possible problems. Im not gonna to reply to your comments if you have anything else to say because its simply not productive. This isnt what this forum is about

 

Keepingitclean, maybe you should start assuming that people who actively mod their TL's would already have done some basic troubleshooting.

In any event, I agree that we should start something more productive.

For everyone who listened to my video clip (and has Megans), is this the same noise you're getting from inside the car?

Keepingitclean, did you listen to it? What do you think?

 

Ill listen to it when I get home tonight. We dont have speakers in school.

 

Hey Elementz, just because I don't own the same shitty header as you doesn't mean that I can't have the same problem with a different mfg. Furher to that I did all the things that you guys are talking about doing and it was nothing but a waste of time and effort, as far as I'm concearned there is no wrap or tightening or anything like that is going to help. As I said I was going to do, here are the pictures realivant or not.

Stone;

Alphawerks;


notice the difference in the flex pipe and the 02 sensor position, have a look at your Megan and let me know what you see, if I'm wrong I'll go away, but if I'm right you've got your hands full trying to fix it. Either that or go back to Megan and get them to fix or replace for you.
Peace, Jeff

 

Hey Jeff. WTF are you talking about? Reread my post bro. I've never even addressed you. Whats with the hostility?

 

What would be your solution to the hanger? I would like to get that taken care of as well. Going to be looking for your solution

 

how tight are the supposed to be? just hand tigthen ?

 

[QUOTE=Elementz] .
For everyone who listened to my video clip (and has Megans), is this the same noise you're getting from inside the car?

My apology then as I seem to be the only one posting here about a header other than the Megan that has the same problem. It really wasn't meant to be hostile I was mearly agreeing that you got stuck with a shitty header as I did with my Stone. Sorry again for the misunderstanding.
Peace, Jeff

 

I have to say that if it is the headers it is due to a piece of metal vibrating on another with the header being the source of the vibration. I would put effort in to finding exactly what the two metal pieces that are rubbing each other are.

 

There aren't that many places where this happens on a header....

1. Where headers bolt to the cylinder heads. People have torqued these bolts many times. Probably not here.

2. Where individual exhaust pipes are welded to the bolt flange. You can see whether the welds are good

3. Where the individual exhaust pipes merge at the collector. Based upon the pictures I've seen of the inside of the collector, this is my guess is where the resonance is coming from, i.e., it's the individual exhaust pipes vibrating against each other.

4. All the other places, e.g., headers to the A pipe and the A pipe to the catalytic converter are bolted with gaskets. My guess is the resonance is not here either.

 

Dude i saw ur video, that is the same damn noise im getting, but mines is weird, it only comes when i turn on the car and drive it for about 3 to 5minutes, after that it goes away, if i park, and turn off the car for like 3 to 10 minutes and turn it back on and drive it its back for another 5 minutes, but in those 5 minutes lol i try not to hit it at that certain rpms that it makes that noise. I agree also, we gotta figure out some way to fix this, or if keepinitcleans friend calvin can resolve this problem for us, since hes the one that makes them. I really dont wanna have to cough out the cash for some used comptechs

 

Mike u retard, i already told u its because ur headers are leaking...

For everyone with the metallic ticking sound, THERE IS A LEAK at one of your gaskets, probably on one of the downpipe ones, and its exaclty how my Megans were when i first got them. Then keepingitclean sent out the new downpipe with new gaskets as he promised...I took it to my muffler guy, he took out the old downpipe, and pointed out one of the gaskets which was dark black on a corner, saying the sound was from air leaking from there.

He put the new downpipe on with the new gaskets, and the sound is gone. So either u need new gaskets, or the guy who did it for u didnt line them up very well so the headers are leaking

 

DUDE, NO WAY! Mine does it real bad when turning too. And I too, try to avoid a certain RPM range cuz ITS FUCKING EMBARRASING!!!!!!!!!

 

[QUOTE=mezzerTL-S]I have the Stone Racing Headers. I purchased and installed them a few months ago. I have had ZERO issues with them. My mechanic was easily able to install them and I inquired about the O2 sensor and he said he had no problem clearing the oil pan. In addition, he stated that he had NO issue getting the headers to align up and bolt up like some people in the past had. I believe the NEW batch of Stone Racing Headers have resolved all past fitment/design issues. The ONLY issue my mechanic had was the bolts that came with the headers were garbage and he snapped a few of them torqueing the headers. He used some SS bolts that he had and the install went smoothly from there. This is my experience with Stone Racing Headers.

All these headers are fabricated individually. Therefore quality control is a huge factor. Because of this, some people may have no issues while others might. Again, if you don't want to deal with the headaches and want a sure deal concerning fitment/design, go with the Comptechs. You pay more and there's a reason for that.

 

If your Megans sound like the video I made, say hell yeah. Say ho ho. Now SCREEAAMM!!!!! LOL, I feel like screaming when I drive my shit now with this fucking noise.


Hey keepingitclean. Did you get to watch my vid yet?

 

any word on fixing this thing?

 

NOPE. KEEPINGITCLEAN is not even responding now.

 

Hey Elementz, Im sorry I didnt have time to check the video beforehand.
Anyways, I just looked at the video. I only the heard sound from your first round. That definitely does NOT sound like leak or resonance. To me it sounded like something is grinding down there. And the sound is very very loud. I have to say it again if you dont mind, check your piping and your exhaust bracket/hook. That definitely does not sound normal. To do so, jack the car up and check the brackets by the piping, cat and throughout the whole catback. Let me know if you need anything.

 

Thanks. Keepingitclean. I will check into it. And yes, it sounds like somethings grinding to me too. And if others are experiencing the same noise I think its a design flaw.

But like I said, I'll check everything out this weekend and get back to you.

 

Please get back to me whenever you can because grinding is not the same as resonance

 

im having the same problem as Elementz except mines goes away after a while, its weird as hell, if i park the car for like 2 minutes and leave the car on or even turn it off, it'll make the noise again while i drive, i HAVE to drive for about 5mins for it to go away, my car is so damn low i hate getting underneath, lol i'll check it out this weekend hopefully though.

 

Your problem might be different. If theres only resonance when you start your car cold that might be due to the downpipe being cold and the felxpipe not being as flexible. The law of expansion and contraction still applies.

 

I will. BTW, what is your definition of resonance...since nobody who is experiencing this EXACT same noise knows what it is. I call it resonance because the noise is so fucked, it resonates in my teeth when I hear it...lol. And it started as soon as I had these puppies installed.

And it only happens when I drive too. This tells me that as the engine turns, it puts out a certain load on the headers/d-pipe creating this noise. Which also indicates a design flaw.

 

So whats the status of that header wrap etc etc.
