Got my headers put in saturday , still havent given the ECU time to adjust and theres a lot of debate if you should unplug your battery or if the ecu adjusts on its own over 7 days but either way they fit perfect, the resonance is there but its not annoying in my opinion and on the highway it feels like a whole new car, i love it. Car is an 02 Type S

 

damn...i cant handle the resonance....i think its because the old stock headers were rusty as hell, including and cat....so when they installed the new headers that touch up against the cat that causes the sound

 

Did you push the car yet? Do you feel alot of high end power?

 

how exactly do you just let the car "adjust"....ive had them on for 4 days so far...should i unlplug the ECU?

 

the car should take care of itself. no need for you to do anything. believe me, you'll feel the difference. there won't be any mistaking it.

i was waiting for this thread

 

my megans brought my car to life.....
especially at highway speeds.
enjoy.

 

now were never gonna get that race in, it was supposed to be tl-p w/ i/e/h/p vs tl-s i/p

 

STOP! you guys are making me want to spend my money on headers instead of getting my kit painted and installed!

 

hell yea right now the biggest change is when you're already going 60 on the highway then you floor it , takes off like crazy

 

Dude go back to english class and try again.

 

my comptech gives my car a new tranny

 

back to the topic...

u will feel difference at the beginning, the car pulls strong for the first 2 days, then the ECU adjust then it will only release the power at high rpm

u need to give some runs to make it adjust

 

Why would it pull harder in the first two days? Do the headers give you any power in the low end?

 

That's sweet man. Hey, how do I know I got the latest batch? I bought my megans from ebay.

 

he would know, since he got the comptech setup,

hey sam lemme buy ur car lol

 

the new one has part # SSH-HA98V6SS.

 

o i c thanks man.

 

i just took off my megans today
thank god...
it's so quiet...
i was really sick of the resonance....

 

yea this damn resonance is kind of annoying....its gotta be a lose bolt or something....im gonna try and check it out

 

i meant to post this earlier...a friend of mine has a 300ZX twin turbo and bought the megan straightpipe for it (at least i think it was a straightpipe). he has the same exact sound. and i helped him install it so we know it's not the bolts. the resonance is just the sound of the gas moving within the headers.

i'm sure some people have loose bolts and stuff like that but i think this helps prove that the rattling noise many of us are hearing is not a problem with the header. they are significantly lighter than stock, so my thinking is that the walls are too think to block out the sound. doesn't bother me though since i only hear it under acceleration.

This is the greatest thread ever, as soon as i replace my shox/struts, they will be in the maiL!

 

you'll be glad you did. my megans were the best purchase i made for the car yet. night and day difference in power. i posted my 'before' and 'after' dyno results earlier this spring. do a search for my name and you should find the threads if you're interested.

Wow, i didnt know that there would be resonance from headers..

 

Next is an unorthodox crank pulley i hear they are the next best thing, like 13 wheel HP just for one pulley, the ac/alternators are not necessary i hear, but i could be wrong thats why i post for professional opinions

 

Go to www.unorthodoxracing.com and look under dynos and you will see the dyno #'s.

 

I liked my UR pulley mod even BETTER than my Megans! The pulley gave me power across the entire powerband while the headers only gave it up top. I just lost too much down low after headers. I gained alot up top, yes. But lost alot down low.

You see, I did the UR pulley before I did headers. Well, after about 4 days with the UR pulley I was in love. There was such a noticeable difference in power it was unreal.

Then I threw on my Megans and everything I gained dow low from the UR pulley was negated by the headers. I'm sure the combination of the 2 mods is a winner. But the loss down low with the headers still sux.

 

Are there any Specific HP gains for each pulley??

 

How can you loose power by installing headers? I dont get it
