is this the one:


Is 2.25" a good size as Perin advertises 1.6" as:
"The proper inside diameter of 1.62 inches is critical. Pre-turbo exhaust velocity is critical to boost response. Improperly oversized header and up-pipe systems lower exhaust velocities slowing spool up for larger turbo's decreasing power and increasing boost lag."

I admittedly do not know enough about the uppipe so if someone wants to give a lesson I am all ears!

Do we need a CEL fix when adding this?

Where did you see this sale? I ordered mine first thing this morning, their time, at the price quoted on their website.

Update: I just called Gruppe-S, the representative asked me if I knew which representative I had ordered through over the phone, which I did not know. He then went on to explain that their server was already down for the night and asked me to call back tomorrow to get things straightened out. I dont want to give any bad publicity for Gruppe-S, I've heard nothing but good things about the company.

That is the one that i have:
http://pg.photos.yahoo.com/ph/wrxdud...9c.jpg&.src=ph
Ignore the headers, it didn't fit so I had to return it.

Lag? What is that? Hehehe, seriously, my turbo spools up quicker than before after I installed the up-pipe. It pulled a lot stronger too! Too bad I didn't dyno it after the install but it was definitely effective. Sometimes it is more practical to just do a trial and error. Thanks for the info about up-pipe from perrin. I guess it would help if we ask someone using it.
No CEL fix installed and no CEL thrown to this day

Over at the "other" subie site. I'd post a link but it may be illegal.
Just call them back and tell them to refund the difference. I know it's 199 bucks regular price shipped.

I only know what I've read and heard second-hand, so take it with a grain of salt... but from what I understand only the very last (right before the turbo) section diameter of the up-pipe is even worth considering as far as turbo efficiency goes. Most of the more engineered designs taper from 2.25 at the header-up-pipe end. So maybe that line from Perrin refers to the pre-turbo ending diameter?

All is good, talked to Gruppe-S today and just had them credit me in their system since I'm planning on getting the helix downpipe in the next couple weeks. As long as my uppipe shows up on time, all will be good

Hehe, kool. You will not be disappointed.
Call and ask for Preston at Grouppe-S, he'll hook you up.

It was easier to swap it from the bottom as I did. You'd have to remove the headers (held by six nuts and two from uppipe). Also remember to remove the OEM temp prob because it will be in the way and you wont be able to pull the stock uppipe out.
You can also do it from top but you'd have to remove the turbo (this is longer process) which means you'd have to remove/separate the downpipe from the turbo.
I have done it both ways and I now like to do the removal/install from the bottom. If you have not pulled a turbo out before, install the up-pipe from the bottom.
LMK if you run into a problem.

It arrived today. I am debating whether or not to try and do this on my ramps or not. Or wait until I do the full exhaust system.

How long does it take to install this thing?

EDIT: pulled it up on ramps, thought about it, I'm going to wait until I do the exhaust. Hopefully I'll only have to take things apart once.

Hey 02_Forester

I got my up pipe last week from GruppeS and installed it yesterday. It took under four hours including cleanup before and after. I wasn't in any hurry either. I followed the Perrin method. I have read a lot of complaints about the install, bloody knuckles etc. It really isn't that bad. Pretty straight forward, way easier than main bearings in a Pontiac Bonneville, but that is another story... Unless you are doing headers, it doesn't make sense to put off the install until you get the rest of the exhaust. It is soooooo worth it A TBE install will be a piece of cake! Biggest PITA was reinstalling the manifold, damn heat shield catches on everything. You may be tempted to put the undertray back on when you get everything bolted together underneath DON'T DO IT, when you drop the screw, socket, Wrench when putting the Turbo heatshield on they will hit the ground w/o the undertray. Fortunately I waited to install it because I had washed it off and set it out to dry better to be lucky than good sometimes.

On a side note, yesterday driving around in Raleigh, I saw 5 other Bajas on the road. I rarely see one, let alone 5.

Good luck!

Sweet, how do you like it? Do you also have a TBE? It can now breathe a whole lot better right? Congrats on the install!

The uppipe takes the exhaust from both cyl heads and routes it up to the turbo. The stock one has a catalytic converter in it. Most aftermarket ones do not. PLus aftermarket ones are normally shiney, sometimes larger and so on.
