how long to install header and up pipe?

I got my gt spec header and up pipe and i wanna know how long to install them. I know the header isnt too bad but is the up pipe gonna add several hours to this job? I read 6 hours and one guy said 10 hours. I might skip the up pipe if its gonna be that much of a headache.

Equal length on my 2009 wrx

I don't know, but I am pretty sure I could do it in about 4 hrs. I have done the headers and downpipe in a couple hours, and with the dp off, I can't imagine the up would take much longer then maybe an hour more.

I don't honestly know. I was a tech for years, and I tend to just dive into this stuff. You will need new gaskets including for the turbo to DP obviously. I'd personally start with the DP removal, then manifold, then UP, then reverse. Really not very hard, just takes time. If you have access to air tools or at least a swivel headed ratchet and wobble extensions or a swivel, it will go easier.

Time involved has a couple factors I can throw in. I'd tell my wife I'd need to plan out about 4 hours to tackle something like that, and make sure I had at least double to accomplish it. Clearance is a huge factor. When doing my downpipe I couldn't get my impact gun between the firewall and turbo to get one of the bolts off. I had to take off the intercooler to get a regular wrench on there with enough leverage to break it loose. That added time. Those are the things that you have to look at. I would take the extra time and do both parts at the same time, as you're going to have to undo them again the replace the up pipe later. I hate leaving stuff half finished, personally. I'd say figure in 8 hours and you're good, but if everything goes smoothly, a lot less. I don't ever plan stuff to go smoothly, because it rarely does.

so prob 4-6 hours minimum. We have power tools and my buddy has experience. He has owned 3 wrx and done about 5 dp, turbos, etc. I wonder if i should ask my buddy to borrow his lift at work, that would make stuff alot easier probably

Do it with a lift. I just did a tbe. I had to take it off another wrx and then take off my stock and switch the 2. It took me (noob) about 3 hours with just front wheel ramps and a 2 ton jack in rear. Not to#fun. I wished i had a lift.

its not bad at all!!!

take the DP off. from the factory its a pain with all the heat sheilds but with an aftermarket DP it should take about 20 minutes to remove. since your doing an UP and header just take the 5 nuts off that hold the turbo to the UP. then take the 6 nuts off that hold the header to the motor. unplug the O2 sensor and boom your done, now repeat. id say an hour or 2 if you take your time.

you might want to unbolt the UP from the header though. i just installed a perrin UP and couldnt pull the factory UP out of the car, so i removed the header and she slid on out.

PS you cant install just a GTSpec header. isnt the header to UP a 3 bolt flange?? your stock header and UP are only 2 bolts.

if you cant find directions everyone above had good adivce. this order should help

1. remove intercooler and intercooler bracket, leave BPV hang there
2. remove heat sheilds around downpipe
3. remove 3 nuts, 2 bolts on DP to turbo, 2 bolts at the back, unplug O2 sensor and DP to tranny bolt
4. remove heat sheilds around header
5. remove 2 bolts that hold UP to header, unplug O2 sensor and 6 nuts that hold header to motor
6. remove 5 nuts that hold UP to turbo and remove UP

do 6-1 and your done

Yeah I'm pretty sure if you take your manifolds off, which you'll be doing to put the headers on, you can pull the up-pipe out without jacking up the motor. If you can do it like that it will save a lot of time. I did my manifolds and it was maybe a 2 hour job. Add the up-pipe and maybe 3 or 4. I'd like to say 1-2 but we all know that never happens.

you cant skip that step is what im saying. you cant just add the header and bolt a 3 bolt header to a 2 bolt UP, must do both or none at all

It took about 4-5 hours only because i had to make two trips to the store for new studs cause the old ones wouldnt come off. So i suggest anyone who installs them has back up studs. And there is a bung on the up pipe for an egt or something which is a total headache. I went to 3 diff places trying to find something that would fit that thread pattern and size to plug it. And heat wrapping the header was a total headache. I would pay double the money for one of the sleeves to save time. It took me 2 hours to wrap it cause there is no space between those pipes at all.

My cobb heat shield does not bolt up now cause there is no shield on the up pipe to bolt it to so u think i should just buy some heat wrap locally and wrap the hotside of the turbo and downpipe? I am getting tuned in 4 days and i dont really have time to order some more heat wrap
