Default Mechanical Assistant + Up pipe Install Write Up

So several things I am looking to accomplish here. I am located in Wurtsboro, NY which is by the border of Orange and Sullivan County. I have done extensive research as far as the Up Pipe install on my 2004 WRX and there are sooo many ways I've seen it done and I just dont know which route to take. I couldn't find a pictoral, detailed write up on these forums, so here's what I would like to do.

First: I am looking for anyone who has done this install, whose local, who wouldn't mind assisting me in installing the Up pipe on my car; I dont mind dishing out some money for your time.

Second: During the install process I want to take plenty of pics, videos, etc. of the install and post it up on the forums.

Anyone willing??

I'm in Little Falls and have had the exhaust system off my car a few times. (Messed up the up-pipe install and had a leak.) Easiest way I've found was to pull the turbo and pull the pipe from the top, the top flange is bigger than the bottom one and is a PITA to get out that way. I took it out the bottom at first but had to jack the motor up and loosen the motor mounts. If I had to do it again I'd do the following:

1. Pull intercooler for space
2. Pull turbo off (watch for coolant/oil lines will get some leakage)
3. Pull up-pipe
4. Pull the passenger side exhaust manifold
5. Put new up-pipe in the hole
6. Attach pipe to turbo and re-install turbo
7. Attach pipe to exhaust manifold then reinstall manifold to head.
8. Reinstall IC

I know this isn't the most detailed description but is the process I ended up following to finally get it right with no leaks or noises. Steps 4-7 are what I had to do to get a proper seal with both ends of the pipe. The turbo attaches with 3 bolts to the pipe and the bottom is only two bolts. I ended up just tightening the bolts without disconnecting the manifold and actually deformed the flange on my cheapo up-pipe.

I've actually watched that video 3-4 times over. I was reading on several forums where half the stuff didnt need to get done. Maybe Im just being paranoid, lol. I want to save the money by doing it myself, but when unbolting important parts like exhaust manifolds and the turbo, according to aperson, it scares the crap out of me lol. I like to consider myself mechanically inclined and learn very fast. Just dont want a major leak or improper install to be my learning lesson.

No need to remove the turbo or the exhaust manifold. Once the downpipe is remove and the uppipe is unbolted from the exhaust manifold and the turbo, undo the 1 14mm nut on the passenger side motor mount and jack the motor up by the exhaust manifold. Jacking the motor up 2" is plenty. Drop the studs out of the turbo and rotate the uppipe 180* and you'll be able to pull it out towards the downpipe.

^^^^ vision.dynamix is correct no need to drop turbo or anything else it's pretty simple drop the headers if you think it's on the way

Dropping it out the bottom weve found to take much longer and be problematic. IMO its easiest to simply pull the turbo and uppipe right out the top and then back in. Its easier to get the large catted factory up out this way.

everyone has their own way, this is the way we do it day in/out

For the turbo you'll have most of it apart already by the time you get the up-pipe unbolted all that's left is the pressure and drain for oil and coolant hoses. If you position it right everything but the bolt on oil will slip right together when you put the turbo back on. It's literally rubber hoses and spring clamps which aren't that big of a deal. I had the same reservation you did until I pulled it apart and saw what it was.

Also if you want to learn to wrench yourself remember that you're never going to learn if you don't try.

I'm thinking of gutting the OE pipe and putting it back in, is this still a good approach or do people have issues with the stock pipe?

Gutting catalytic converters exposes you to chemicals that can give you lung cancer.

A gutted catalytic converter does not flow as well as a catless uppipe.

However going catless is indeed still a good idea

Going catless doesnt cause you to directly handle the carcinogenic materials.

An STi up-pipe is factory catless, just buy one of those. (I have one if your interested)

As is the 06-13 WRX UpPipe.

The factory uppipes only solve the issue of the cat breaking up. They still flow like garbage.

Careful with this method. It works, but with the turbo on the end dangling, it's also a recipe to crack that brittle OEM plastic turbo inlet. (or potentially "unseat" an aftermarket inlet)

I thought the only problem with the OE UP was the cat? Once removed it flowed well enough that an aftermarket unit isn't much (if any) improvement?

None of the aftermarket pipes are larger diameter, right? The EM and turbo inlet sizes aren't changing.

I would use a factory catless uppipe (commonly found used for $50) in a second over gutting the factory catted one.

On anything VF sized or down, the gains from an aftermarket uppipe are small (but exist)

A 244 to 292 CFM improvement was good enough for me!

Question. Would the install of an up pipe differ from an automatic and a standard transmission? I was looking into my engine bay, the part does not seem to hard to pull off from the top. When I bout a downstream o2 sensor it differed from the automatic and standard transmission; just wondering if the install of this part would differ as well depending upon the transmission?

Bump. Yes I know, I'm bringing it back from the dead, but I was wondering if you ever did do the up-pipe install, and took those pictures like you said. I am in the same position you were, worrying about screwing up. I've heard mixed things. i.e. Don't pully the turbo!... and Doing it from the bottom is PITA...

OP hasn't been on here in 2 months. Probably better off shooting him a PM than hoping he comes back to this thread.
