Sorry, what I mean is - is 28 ft/lbs something you can torque down using simple hand tool..

that is usually not quite enough

i always tighten eveything to 25ft-lbs and then go back and up evrything to 35ft-lbs and done

i get few leaks

and to get any proper torque you need a torque wrench

Yes, 28 ft/lbs can be managed with even a small (6 inch) 1/4" drive... It's tough, but can be done. However unless you have a torque wrench, and if I had to GUESS, most people will overtorque everything because they think its a lot. The few things people tend to undertorque is the crank pulley bolt, Cam gear bolt, and axel nut.

Do yourself a favor and buy a torque wrench... yeah they might be stupid exhaust bolts right now, but what about when you finally do your TGV's, or clutch, or timing belt? there are more precise bolts that WILL snap if overtorqued... ask me how I know. ( For the record, I set the torque wrench properly (7 lbs) for the small intake to TGV bolts and my friend picked it up and set it to 18 lbs to get the longer TGV to block bolts. I didn't realize he did this and I snapped one off. )

I just want to know if it's possible to replace the uppipe without removing the downpipe. Since I'm only going to be doin the up first, I'de rather not unbolt the stock downpipe only to put it back on. Yuck.

If I had more money i would do the down at the same time, but thats not my case

One of the bolts is right under the DP flange. RIGHT under it. You have to unbolt the downpipe from the turbo and move it back like 2 inches to get to the nut. The good news is that it's really easy to do this if you have the stock downpipe.

After researching for months I finally bought a used 07 STI uppipe for my 04 wagon. I felt $60 was better than me cussing and busting knuckles removing the Cat. So I got my new gaskets and decided I'd take it to my mechanic instead of me suffering for a day or so. I have some tools and jack stands, but really no help unless you count the wife pumping the breaks when I installed SS lines, lol. So after it was all done $60 for the Up, $30 for gaskets, and $268 to Dixie Dan for labor. The only work I did was the resistor mod before the work was done.

I am very pleased with the sound and throttle response. My gas mileage is better, too.

Unbolting the downpipe is least of your problems with doing an Up pipe lol. Good luck!

You should have saved your $268 and done it yourself or maybe with a buddy. Its really not that hard but oh well its done now for ya!

2 1/2 hours for me. I have mechanic experience, nothing major though. Jack stands, in front of where my wife used to work actually.

Yeah, none of my buddies are remotely able to work on cars. $268 was money well spent IMHO. I have no cuts, bruises or high blood pressure from the install either, lol!

The uppipe was easy, maybe an hour. Guess I'm spoiled with a lift in my garage! :-)

You want a challenge? Try motor mounts! Not much fun with everything still in the car.

I wish I had paid for I installation. I sheared off part of my head when a nut seized on the header. Bad times....

Both are easy with the right tools, and you only need a minimum of jack stands/ramps.

The problem is that it took a couple years after the bugeye for the process to be well documented here.

Ha thanks guys, so the downpipe isn't my worry. What about having to jack up the motor an inch or two to pull out the original uppipe? That sounds a little outside of what I have in my garage

You will more than likely have to jack it up. Easiest way to do it is I remove the nuts on the motor mounts. Stick a 2x4 on your jack so you don't punch a hole in your oil pan, and lift a couple of inches.

It's no big, you can just loosen the motor mounts (14mm easy to reach, but may need a breaker bar) and jack the crosspipe. Don't jack the oil pan. Or you can do the 2x4 thing mentioned. Slip one end between the oil pan and exhaust manifold and put the other end on the jack.

It's not like you're pulling the engine, you're just raising it an inch or two to get clearance between the fender and the block so you can get the pipe out. Nothing to stress over.

Motor mounts are a cakewalk compared to the UP.

Hello, just lost a turbo due to my up pipe coughing a healthy chunk of cat into it. I have a broken turbo inlet pipe and an O2 sensor on the up pipe that has a bad heater circuit all within a month. Good thing it all happened at once... I want to go catless up pipe, but if I do, is there an O2 sensor bung in any of the decent priced parts out there? I have everything apart and Im just waiting for some cash to get ordering. I need the following parts, any input would be much appriciated!

Turbo - as close to stock as possible, needs to still be a daily driver
Up pipe - catless to prevent this from happening aga7n, but still have a bung for the o2 sensor
Turbo inlet tube - not a b7g deal if I have to pull intake to get it in, I destroyed the broken plastic p.o.s. removing it.
Intercooler hoses if I have cash, the plastic is just not really giving me a warm fuzzy and since I have it all apart...

I live about an hour and a half north of detroit, so if I need to have it tuned after, its not a major deal just need to know what people out there are recommending. I have about 160k miles on my 02 wrx currently, I was getting about 26mpg on average best was 33mpg on highway last 4th of july and I would like to keep it that way!

Few things:

1) The O2 sensor is in the RH exh. manifold, not the uppipe. There is an EGT sensor in the uppipe which can be deleted (it's only there to monitor the pre-cat), just run a resistor across the connector contacts.

2) you can remove the uppipe fairly easily from the top side with the turbo out of the way

3) get a silicon inlet, a hard inlet will ave you hating life after about 4 hours of fitment struggle

Ahh, I saw the sensor on the uppipe and assumed it was the o2 that I have to replace. I'll search for the resistor to hardwire in soon on the forums. I saw a replacement guide for the o2 sensor elsewhere on the web, got the denso part number and the 22mm socket bookmarked already.

Yeah, the uppipe looks pretty manageable now, plus my nephew is a mechanic and had pretty good luck with all the bolts after some pb blaster and 15minutes wait time, even the heat shield on the turbo came off without snapping any bolts.

Perrin has a wire reinforced silicone hose, probably going with that, just thinking about taking the intake off to get different ones in make me groan... clipped the pcv valve adapter and the old one came out just fine

Thanks for the support everyone! I was on the right track but I wanted to make sure I took care of my wrx as well as it has for me in the past 12 years now that I can afford to do some of it.

Has anyone done the install without disconnecting the Dp from the catback? I didn't order a new gasket for that section and was wondering how much harder it would be to do it if I just dropped the Dp and moved it out of the way? Or if I completely removed the whole exhaust system as a whole? Any insight would help! I wanted to start Sunday since Monday was my only day off and it gives me enough time if I hit problems.

dropping the entire exhaust is pretty common and works well, but it's a lot easier with a second set of hands. ..
