I just did my UP pipe install this past weekend. I bought a stock one and gutted it. (trying to stay stealth). I figured since i have everything else appart, I went ahead and ported out the ex. manifolds. I didn't port them as much as I wanted cause I had to have the car back together for work on Monday, but I made sure I worked on the short turn radiuses. I probably spent about 3-4 hrs porting just the drivers side ex.
I already had the Cobb stg 1 on the car, which made a significant difference. Not only does it increase the power, but it smooths out the entire RPM range. before, it was like the car had an on-off button on the boost, but the Cobb made it much better. The UP pipe did help the spool-up time and helped smooth out the acceleration even more. I can't tell if my car is any louder though. I guess I'm done modding my car for now. maybe once my warranty is up, I'll add a DP
hey is the turboxs 4'' down pipe agood choise or is it too big?
just finished my up and down install this weekend, and had a little bit of trouble getting the hose from the intercooler to the turbo back on... figured out if you warm it up a little bit with a hair dryer it helps it slip back on.... hope this helps somebody

Man those nut's on the Turbo are tight ....I am in serious need of a breaker bar.
going to get it on the lift on wednesday, and get that thing installed.

I'm not saying its impossible, but unless you can rebuild a VW with only a hammer I recommend following the original instructions and get the O2 sensor tool before you start. I can't even get the wrench near the one on the manifold because of the shielding.
I am shocked and amazed that my install thread is still alive and kicking!
I just got a new TD05H-18G turbo and PE650cc injectors and APS Turbo Inlet and TGV Deletes and NGK Iridium cold plugs and fuel pump. They will be going on my car over the Memorial Day weekend, and I'll probably take loads of pictures and make a nice DIY for turbo installs for everyone. (There are many out there, but I'm confident I can put together a better one)
I'll keep you all posted, but thanks for the compliments, and I hope this DIY has helped you muscle up the courage to do your own installs on your WRX/STI!

I have question.I got my perrin uppipe for my 2005 sti,do I need some modification on it? or what can I do with sensor(O2) thanks.
Today I went to get a straight pipe put on and found out there is a O2 sensor connected to the cadilatic converter. So as soon as I turn the car on the Sensor will set off the code. How to fix that issue? Do I need to re-program the PCM?
just found this after searching all over for a good step by step guide to install a downpipe and upipe since i have a cat back on now.
this is hands down, amazing.
this makes me wanna drain my account , order them now and get my hands dirty.
i cant wait to order them now, a few more weeks and ill be set.
just one question...
did you back the car up onto the ramps....and then jack up the front then put it on jacks?
seems kinda sketchy, but just wondering....
eitherway, this tthread is amazing
Somebody is going to kick me off clubwrx for diggin up old posts.... I used these pictures to put my COBB DP on my 07 WRX and it was amazingly useful. Thanks to the OP (if still around).
1 thing I would suggest to those who may be doing this the first time.... I would recommend backing the car onto ramps and leaving the front end down. I had all 4 wheels on ramps and found working with the IC and heat shield very difficult from standing on a chair. I am 5'10" and had to use the chair to reach some of the bolts. When I was putting it back together, I put the front down and left the back up (you really can't move the car without the IC hooked up) and found it so much easier to work with.
I didn't have to "wrench" too hard on any bolts, but I felt very safe under the car since it was supported by its own shocks on ramps. I don't think I would have felt safe pulling on the O2 sensor if the car was on jack stands.
