finally i finish installing my header yesterday it took me 2 days so if you dont have mechanical experience just take it to a shop.
im not responsible if anything goes wrong do this at your own will

Tools you will need to finish this installation
•set of socket ranchers from 10 mm to 14mm
•set of ranches from 10mm to 14mm
•a universal ranch (for the sensor on the exhaust)
•extension for socket ranch 20”
•pipes long pipes(not to long and fat enough to fit the ranches this will be use for more leverage I don’t know how to spell it but hope yah know what I mean it makes the installation much easier

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

Step two
Under the car u need to remove your dirt guard, to make it easier to reach jack up the car but don’t lift it off the ground, u don’t need to do this till later, just enough to give u room to get under and take out all the bots and nuts and shit, ill point were they are in the picture below

Picture two
on each side of the car were your wheel is located take out the 3 screws or what ever they are out of the way, ill point them out do this on both sides

Step Three
First disconnect the 4 ignition coil harnesses pointed in the picture

Then remove the 4 ignition coil bolts on top of the valve cover (10 mm)

Now remove the bolts and the 2 harnesses shown in the picture below

Step Four
Its time to take out the valve cover but first we need to get this two nuts (10 mm)

Next remove all 9 screws from the engine cover

2

3

Now your engine should look like this
(note: credit for the last 3 pictures goes to the teamcelica installation guide on the lift bolts)

also make sure u cover the camshaft and shit i used a clean paper bag and put it on top so no dirt and shit could get on it

Step Five
Now there are 5 screws on the top heat shield ill post the right hand side of it and then the left side okay

left side
sorry the harnes in on the way but u can find it if u got this far
also i removed the battery to get to this botls, u should do the same

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

Its time to get under the car
Jack up the car and make sure u put it on jack stands u don’t 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

far side

Note I tried everything I could to get the heat shields out at this point but its kind of impossible so don’t try it would be a waste of time
(credit for the last 2 pictures go to the person that made the other installation guide on the header)

Step Six
Remove the bracket that holds the header there are 3 bolts there (14mm)
Make sure u hold it its heavy and mite hurt u if it falls on u

Step seven
Now we are going to take out the exhaust pipe to make this a whole lot easy
First take out the 2 bolts connected to the header there 14mm

Now go down the end of the pipe and get the other two there also 14mm

Now disconnect the sensor by using a universal ranch

second sensor

And try to do this to get the rubber hooks out of the exhaust

Now its time to make more room
Remove the heat shield it has 4 nuts there 10 mm

Now remove the other head shield there are 2 nuts 10mm right under the hood here is a pix now there should be about 2 more nuts under the car get them off before u can remove that heat shield I forgot to take a picture of it sorry but if u got this far u can figure it out

Now with all of this out u 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 here is the biggest bitch to do, getting the header screws out
There are 5 here is the picture
(Note the only screws u can get from above the car is the one in the middle I took all the other ones from under the car
(picture credit to the other install guide)

Now on the other installation guide they say to remove some shit that has to deal with the suspension but I don’t think he remove his pipe that’s 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 don’t turn it or anything u should have enough room to get it out.
After u get it off put the new one on just the way u took the stock one out, it should not be hard after that bam you’re done.
Here is the after pix from under the car and above it

note i had not bolt the exhaust to the header yet so yeah. the fitness is perfect and i can feel a lot of torque and a lot more power wen im in the 7 rpm range, great mod
here is the pix from above

any questions feel free to ask
and yes i did left the heat shield off, y? i dont know u dont have to leave it off but i just left it off cuz i was 2 lazy to put it back on, but if u want 2 u can put it back on, it should fit perfect
