I think when buying an uppipe the most important thing to consider is the diameter of the pipe. There is a reason why Subaru made theirs that size. With that said, Vishnu and the catless Subaru JDM pipes are the best. Shiv makes his the same diameter as the stock pipes. And I would avoid uppipes with flex joints.

I would think the flex joint is very important.
I had expierience with another turbo car that would NOT run right after replacing the flex joint in the exaust. The reason was the motor was picking up knock thru the exaust and retarding the timing.
Let me tell you... Its not an easy thing to figure out.
I like the idea of the flex joint... but the price on a nice pipe with it is HUGE... and im poor

Yah what whack-job's would put an unreliable flex joint in the uppipe sheesh! (Stock!?@#?!#)
The absolute best bang for your buck is to gut your factory uppipe and re-install it. The Subaru engineers are no dummies.
Paying $300 for an aftermarket pipe is insane. At least when you have somewhat limited funds to pipe into the car.
I just paid $80 for a gutted stock pipe, and am about to pay 120 for the install. It will fit like stock, take the stock EGT sensor, look like stock, blah blah blah.

I dont really think a gutted stock pipe is very good for performance. It is very restrictive for a few reasons.
It will probably be better than stock, but not close to the gain of an actual aftermarket piece.
But like you say you wont have fitment problems and thats always a plus.

If you plan to tune the car on a dyno, it's nice to have the extra O2 bung. Some place it just before the turbo and others go for just behind.
You'll "get what you pay for on up-pipes" The lower flange is a critical spot for leak free installation using the right directions.
Having installed Vishnu, PDE, Turbo XS, MRT, Godspeed, and Perrin pipes, my favorite is the Vishnu. Superior quality, perfect fit, and the extra bung for tuning.

I understand that if you want a bigger turbo or a wideband bung...then aftermarket is the way to go. But just the fact that I won't have warranty issues, or issues with that EGT bung falling out is basically what I was after.

"Could you elaborate? From everything I've read...you don't want to make the uppipe diameter larger (slowing flow before turbo = bad thing)."
exactly. velocity is your friend. It's not an exhaust. The only thing that I think is bad about a gutted stock uppipe is turbulance.
So your gutted uppipe, is the inside smooth or is there a larger diameter where the cat used to be?

The STi uppipe has a flex joint in it as does the oe piece, this is one of the reasons you hear few if any complaints of leaking. This was my main impetus for selecting the STi pipe (I had heard enough horror stories about leaks). One can argue the virtues of pipe diameter and flow, but 90+% of gains w/ a uppipe are the simple removal of the cat, this includes the faster spool.

Best I can do. (Actually the best that sr20det91 could do after he finished gutting it for me).

Might be a bit of turbulence. For $80, it don't bother me a bit!
