Headers, DC Sport Header (GTS) - Install Guide

Celica GTS DC Sport Header Install Guide

I finally finish installing my header yesterday it took me 2 days so if you dont have mechanical experience just take it to a shop.

I'm not responsible if anything goes wrong do this at your own will

Tools you will need to finish this installation
- set of socket wrenches from 10 mm to 14mm
- set of wrenches from 10mm to 14mm
- an adjustable wrench (for the sensor on the exhaust)
- extension for socket wrench 20
- pipes, long pipes -- not too long, just fat enough to fit the wrench handle. this will be used for more leverage. it makes the installation much easier

Step one
First you need to disconnect your negative battery terminal (10 mm)
(Note: you should just remove the whole battery, its going to have to come out later on)

Step two
Under the car you need to remove your dirt guard, to make it easier to reach jack up the car but dont lift it off the ground, you dont need to do this till later, just enough to give you room to get under and take out all the bots and nuts and shit, ill point were they are in the picture below

to make this easier use the pipes i told you to get put them at the end of the wrench and this should make it a lot easy to break the bolts and save you a lot of strength
(note from now on you should use this method to break every bolt)

Its time to get under the car
Jack up the car and make sure you put it on jack stands you dont want to die trying to install something.
Now we are trying to get the bottom part of the heat shield off there should be only four on this one the first picture are the ones closes to the engine and the one ones are away from it

Now with all of this out you should be able to try to get the head shield out im not saying its going to be easy because even with this it was hard what I did was take the top head shield out of the top of the car and when it was not coming out I started to harmer it and it came out and the bottom one just pull it and move around to get it out

Now on the other installation guide they say to remove some shit that has to deal with the suspension but I dont think he remove his pipe thats y he had to do this.
Now pull the header just the way it is it should come out it took me 15 mins to figure it out. Basically just pull it from under the car grab it by the ass and just pull it dont turn it or anything you should have enough room to get it out.
After you get it off put the new one on just the way you took the stock one out, it should not be hard after that bam youre done.
Here is the after pix from under the car and above it

What is the factory tourque for tightening the bolts? And I do not mean "as hard as you can", or "The tighter the better". There has to be a spec. Thanks.

it dosent say any were that you have to torque them, and i would say as hard as you can, you want the right torque call dc or ur local toyota dealer, it has to be tight enough so you wont get licks and get that ugly sound

You can't use the DC header with an EGR valve, it says it right on the box, before you even open it.
