Engine Header Install

Header Install

Anyone have a DIY for installing a header on an 8-gen? One with pictures would be even better. TIA.

I don't have a diy but have done header installs several times. It isn't hard to do. Unplug and unscrew the O2 sensor(if you gave one in your header). Unbolt the exhaust manifold which should be 5 bolts. Unbolt the down pipe before your cat which will probably only be two bolts, three at the most. Then just do it in reverse. Are you doing a hi flow cat and exhaust too?

I'll probably do the whole thing when I decide to do it (Read: get the money to buy everything so I can do it all at once). I bought the car used and the previous owner looks like he put on a Midas or Meineke exhaust system which is welded from one end to the other.

So much for installing a Cat-back.

I guess my other concern is having to deal with rusty bolts and possibly damaging the O2 sensor.

the rusty bolts are definately a pain and you should damage the O2 sensor. if you can get the car up in the air, everything would be a lot more simple but it is do-able with some jacks and jack stands.

That about this one?

I take it I should stay away from those $40 ones eBay also sells.


And if I just shoot the bolts up with Liquid Wrench and let it sit overnight, do you think I'd be Good to go?

it wouldn't hurt. it really depends on how bad they are. mine, from driving up in wisconsin, were solid. I had to use a cutting wheel to get them off.

I think I have an old DIY or something similar from a while back. Just dig around using my name to search for it. lol

Is a header a must to add power to the 1zzfe vvt-i?

NO. It was too much trouble than it's worth.

lol don't install that shitty obx exhaust header. you'll regret it and wished you listened to this advice.

Then if the OBX is no good, what is a good one? Or is there a good one?

none that i know of..there's this mystery ebay one...i wouldnt trust it though. just went back to stock earlier this week and no more CEL.

vibe is the man, THE MAN MAN MAN.

i am reverting to stock soon, already have my stock exhaust header sitting in my room.

Dang good thing I never bought that OBX...

since there's no good header why not to port and polish the stock one,its probally cheaper and better instead of buying other header that dont give any hp.

I'm with xplicit

polish and work it, much better than shit ebay stuff

And you won't get lip from police either.

Why's everyone going back to stock? Vibe was complaining that the TRD muffler was too loud. I hardly notice it sometimes.

Port and polish is probably the way to go

From what I understand, it's pretty easy to do, looks unassuming, and actually nets a few extra ponies.

cgreen you forgot the most important bit almost for free

There is someone who makes a race header for the celica 1zzfe and ive heard it will clear our firewall if you cut it and install a flex pipe (which you will have to do anyway) and its quality stainless steal. but its 500 dollars.

I've finally got my exhaust system completely vibration free at idle and during acceleration. i haven't had this in my corolla for almost 2 years!

if you hardly hear how much the trd muffler drones your cabin then you must be deaf imo. I have A LOT of dynamat on my car too..

furthermore.. i used to set off car alarms in parking garages...i never had to honk my horn to let my ex-gf know im in front of her house...she can hear my muffler from far away.

i could hear you across the country.

loud is good, it makes crossing the street safer for young children and the blind.

LOL @ the prius incident.

lol. to each their own, i suppose.

PPE engineering here in tempe arizona

i was asking about the header and a 2.25 exhaust with a magnaflow cat, and a HKS resonator, to my current muffler(magnaflow), and they quoted me 1000.00$ for the entire thing with it all high temp painted black, i gladly declined

lol yeah. not worth it.

What about heat wrapping the headers?
Also is it worth it to put a High flow catalytic converter?

Fixed and nope.
