Question EJ22T Up-Pipe Compatibility?

Just curious if any of you guys have tried or know if the factory cat-less up-pipe from the 91-94 Legacy Turbo's are a direct bolt-in replacement for the factory WRX up-pipe with cat? The flanges look identical, but I don't know about the length, bend, etc. The older WRX headers and the Legacy Turbo headers were just about identical IIRC.

Subaruparts.com has them listed for $187.03 I think. If they fit, just have the O2 bung put in by a muffler shop and your set. Not trying to sell Shiv or BPM short, just curious if they would work. Might be especially helpful for those who know where a few Legacy Turbo's are sitting in salvage yards as well.

-Matt

Edit: Part number is 44104 AA010 and comes with heat shields I believe.

for $187 you get a stock skinny uppipe without a EGT bung. Add $20 and you have a stock skinny uppipe with an ugly weld for an EGT. But, for ~100 more you can have a race quality uppipe from Vishnu, for example. Why bother with a stock pipe?

Why bother?...Why not?

If you truly know that the aftermarket up-pipes, like Vishnu's for example, give an extrodinary increase in performance over a stock EJ20/EJ22T factory catless up-pipe(no speculation based on looks or reputation), then I would say, yes, don't waste your money and time with a factory up-pipe.

But who is to say that the factory cat-less up-pipes don't provide a substantial increase themselves and that by going to an aftermarket up-pipe would have minimal gains, if any, over a OEM cat-less up-pipe?!?The fact is, I don't know. Hell, I don't even know that it would fit. But it would be nice to know if it would fit, and regardless of how it looks or will look after you get the oh-so-ugly bung welded in, I will go out on a limb and say that a factory cat-less up-pipe would outperform the OEM up-pipe that's on my WRX right now.

And not for nothing, but, although there has been mixed opinions, it has been said time and time again from many different tuners that, despite their looks, the factory header system(two manifolds, cross-over pipe, up-pipe) on the WRX's do not pose a much of a performance hinderance. Sure the WRC car doesn't use stock headers, but they are also trying to get 300+ hp and 400+ lbs/tq sucking through a 32mm restrictor, they need all the help they can get. That being said, I'm sure the factory cat-less up-pipe would work just fine for me, going by it's track record from years past. I don't always need the biggest and best of everything(not implying anything, just speaking for me personally).
