Celica Forums General Discussion Exterior Got my header installed

Got my DC sports header installed today, feels good, but it idles rough right now, the mechanic told me it's gonna do that until the MAF works itself out and not to worry!

AND, i finally got my exhaust the way i want it was rubbing against my camber braces but now it sits at an angle and looks really good. the whole new setup sounds great too, now all i have to do is get my Intake looking good again and i'll be set!

cool can you feel the gainsfrom the header

What kind of exhaust do you have? Can your hear the header over the exhaust?

why does everyone ask this?

congrats try cleaning your MAF. it wont just magically fix itself.

Because I wanna know if I'm going to be able to hear my header over my exhaust.
Edit: Which is a TSRM.

I just cleaned my MAF, get better throttle now.

Get a bigger throttle body and fuel injectors too

pics of it installed??

IF yall want to no what type of exhaust, Intake or whatever else he has, the first thing yall should do is check out his profile by clickin on his name!!!!!!

wath is MAF ? and how does a header sound like?
and wath did it cost to get the header innstaled and how long did it take?

its an HKS exhaust by the way if yall are to lazy to do what i just said

same question here

MAF is your air sensor thingy. Probably needs a cleaning. What happened to the post on cleaning the MAF sensors? Didn't somebody bump it TTT? Just search for it. Its important, so get it cleaned. Don't ask why, just do it!

Ummm Fuel Injectors on a Celica? I didn't think we had Fuel Injection.

^^^ ROFL

sicc...nice mod

how does it feel ?

Uh, yeah.

You either have to have a carburetor or fuel injectors. Since carburetors went away in the early ninetys, fuel injectors reign supreme, at least for cars that is. You still see carburetors in lawn mowers and such.

The mass air flow sensor sort of "weighs" the air coming in through the Intake, and tells the ECU how much fuel should be injected into the engine. Too little fuel and too much air, and you run lean. Too much fuel and too little air, and you're running rich.

The only aftermarket header I have heard was for a 93 Cobra and 00 SS. Sounded like a hiss, and sounded really clean. No other way to explain it.

And about hearing your header over your exhaust...

I think the Intake would be louder than the header in almost all conditions.

okay to answer the lazy folks question:
1. it's HKS hyper.
2. no i don't have pics up yet, but i will as soon as possible.
3. i had to have my exhaust re-routed because it was rubbin against my camber links (bought the same muffler as HKS hyper, but instead of wasting $300 getting the prefitted bolt-on pipe, i just had the muffler place do it) now, to install the header and the fix the exhaust they charged me $150, and it only took them about 5 hours, so i didn't even really notice that i didn't have my car.
4. I can hear it not necessarily OVER my exhaust, but the car definitely sounds different. the only way that i can describe it is that is "clacks" a little more, like a built mustang or something if that makes any sense.
5. It's not my MAF cause i just had a new one put in, the mechanic said that the ecu has to get used to the new part an recalibrate itself to accomodate; he said it would take approx. 45-50 miles before it would stop
6. AND FINALLY- yes i can tell a difference, a lot more torque, i don't have my Intake on at the moment, i had to take it off to get past emissions, and when i was putting it back on i scratched the powder coating off...down to the bare metal, so i have to get it refinished before i'm gonna put it back on... hope this answers everyone's questions, if y'all have any more let me know!!

nice nice congrats

were did you get urs from and wats the upc or numbers on it. i dont wanna get the GT header, thanks alot

got it from nopi, the part number is 251+2669

The official part number is THC4403!

i dont have an aftermarket exhaust, but, i have the hotshot header and an AEM Intake, and you can hear the two distinct sounds- "hissing" sound coming from the right where the header is, and the all familiar deep sound of an Intake from the left. not exactly answering your question, but, wanted to throw that out

No no, I meant an aftermarket for it, lol...

thanks ya im going to order mine soon

I just ordered a DC header for my 2000 GT too. Should be here on Tuesday! Can't wait!

is mwr selling the header yet? only 259 there + ship

i looked at them yesterday, it still says available soon, check it out though

If you hear a Hiss from your header you prabally have a leak somewhere. the only thing you will gain from a header is maybe a louder exhaust, but definetly more torque. Depending on how long the runners are will determine the RPM the torque is gained at.

were are the pix

I just ordered the DC Sports GTS header. Is there anything else besides the (header?) gasket that I need? What is the Toyota part number on the gasket? Thanks...

the part number for the gasket is 17173-88600 either order one from the dealer or partznet.com has em for 14$!

Thanks

only 14 bucks, sound good to me

why don't you just pull the ecu fuse?
reset the ecu faster that way

i'm not trying to reset the ecu, i'm letting the ecu adjust to the new header...plus, it's not idling rough anymore, everything is great

Your mechanic was supposed to pull off the negative battery terminal when he installed the header in the first place, which would have reset the ECU regardless.

it was installed yesterday. Good gains in torque, horse, and sound throughout the power band.

^ it sounds much louder than before

yep deeper exhaust sound

No need for that. We pulled the header out towards the back of the car buy unbolting the exhaust and letting it hang from the car. It isn't hard at all, only took a few minutes to figure out how to take it out. And took even less to pull it out.

what is the damage if a header is leaking ??
Or you have a leak due to used gasket ??

thanks

Anyone else installed DC Headers and acheived good results?

Good results? All I heard was pretty much bad. I'm glad I held off on this until things get sorted out. MattsGTS2000 did you have a dyno before and after the install? I'm still waiting on this and nobody has yet to prove if this header makes HP and TQ. Maybe a HP or two, who knows. Hows the quality? I know many people are having issues with this mainly.
