Yah those are nice...but you still have to use a resistor. Check out http://www.i-speedusa.com if you're in the SF Bay area. They have bunches.

JDM up-pipe= Legacy 2.2 liter turbo uppipe for the record and available in the states 9not sure on cost though)..yes you either need to weld the bunmg or fit a resistor, as neither the new age STi nor old Legacy Turbos have the EGT sensor.
The Graham Goode is a really nice piece....we have sold it since day 1.
The BPM, etc with the flex is a bit beefier....all polished, very thick flanges, etc....quality piece for the price.
As for diameter it comes down to matching. the up-pipe is a bridge between the manifold and turbo, so ideally, it should be port matched to both. To big or too small and you get loads of turbulance at the flanges...small helps spool but kills top end..big does the reverse.
Stock diameter is fine...it matches both the turbo and manifold well

the manfiold is made of iron, so why does the upipe have to be made of stainless steel?
the txs upipe, expands, flows and retains heat exactly the same as the stock exhuast manfiold, which is crucial for maintaining exhuast gas velocity to the turbo. its also the same diameter too.
like..having a stock upipe, with a two bungs, and no cat

I'm buying the Perrin upipe because of it has 321 SS, and does not have any EGT bungs which I do not need, if I ever put in an EGT sensor I will tap the manifold most likely. Also it was an ok deal at $249, comes with new studs+gasket.
The STI and USDM OEM pipe does have areas in it that enable the pipe to expand and contract, I'm sure they put it there for a reason. Hopefully I will have good luck with my solid Perrin pipe though.
For those interested, you can purchase new STI catless upipes from Rallispec.com
