Celica Forums General Discussion Engine and Performance Stock vs dc headers

which one is better without any mods just the headers?

they just give better sound

technically they should give you a bit of performance improvement, but it seems none of the headers out there works good for Celica. My buddy has a GT with headers on (probably a DC headers) and all it did was made his TRD exhaust louder than mine. I'd say save your $200+ for other mod.

how about porting stock header and ceramic coating it.

if you were to put a dc header on an otherwise stock car you should see around 10 hp gain. we got 10.3 whp gain to be exact.

but once you get I/E it loses it's affect.

^^^ wow didnt know that.

Lucky Knows all!

^^ not even close. BUT my car was the prototype car for DC so we did dyno it just like hes askin about lol

About the headers should i put back the stuck one or should i remove my injen intake.

I was thinking about getting trd exhuast, but since you sad they would get mix up and would not work good.

Whats your advice to me a biginner in toyota. What should i do and what parts are good for my car (GTS02)

By the way is the AEM pully works good on celica

just fork over about $800 bucks and get the trial header

i heard trial doesn't do much either...i guess it's all waiting for tpr as usual

im sure porting your stock headers might do it, i read it on the other site, probably 5 at the most, right now thats the best thing we can do as far as header, but we can wait for TPR and see wat they come out with.

some quality headers would be nice-oh well too bad for us we pay more for our cars and cant get anything for them meanwhile you can get a $3000 civic and they make everything performance for it so unfortuantely some civics will most likey kick our asses if they spend the right money-

the headers are only useful when you put them on the car STOCK. Like Lucky said. When you add Intake and exhaust, there's barely 1 WHP gain. So it defeats the purpose of having a header, for the I/H/E combo. The only way you can actually get the I/H/E successfully to work to about 190 hp+ is if you have the PFC or ecu upgrade.

Trial is sooooo not worth the money. You're paying for the name only.


for a 2002 celica you should get the power fc. this will let you raise your rev limiter

Other then that the TPR intake and exhaust works really good.

if you have i/e and you port out your stock header will you gain more then 1 hp or will you get the same results as dc sports and only gain 1-2 hp..cause of the i/h/e combo

you should get around 3 hp

yeah i would say the money for another mod. I mean average 3 HP for such long work for taking out the stock header and putting in the new one. I dunno aint worth it.

Yeah i heard even the rare and expensive TRD header doesn't do squat...if you want 3hp over a stock celi...well just taking out the butterfly valve on the intake gave 3-4hp on the dyno believe it or not...search for the thread

You should get the GT Fabrications Header that I have! I have no idea if it works yet though. Waiting for summer.

What about the PPE headers and mid pipe? I already have the dc headers on my celica but I heard it actually robs torque on the low end, they sound nice and it pops when it wants to, I want to get a mid pipe but the only mid pipe they sell is a ppe midpipe is it worth the 1500 for both?
