Agree they are the same size.
If you fit samco (other hoses are available) turbo hose's for the WRX/UK intercooler, they are actually a slightly larger bore and better flow then the STi ally link pipe.
An image of and STi8 link pipe Vs MY99 WRX/UK samco can be seen on my DIY STi 8 intercooler thread (note thisw refers to the STi 8 intercooler which is larger, but you should get the idea)

Samco Y-Piece Vs STi
Originally I fitted a 90 degree elbow to the Sti Alloy Y-piece, as recommended by alot of other people that have done this. However, this did not fit too well and caused the Samco to twist and kink slightly. The problem appeared to be that the MY00 Samco bends slightly upwards and sits closer to the Intercooler.
I thought about attacking the standard MY00 Samco in order to get a better fit.
But.....when inspecting the 2 types of induction pipework I noticed that the size/spacing looked the same between the STi Alloy Y-Piece and Samco Y-Piece. Infact the Samco appeared leass restrictive.
Hey presto a quick swap and the MY00 Samco and Alloy fitting are on the STi Cooler and looking like they will fit.
1. Swap MY00 Samco Y-Piece onto STi Intercooler…..then place STi 8 Alloy Y-piece on Ebay
2. Adjust Samco Y-piece slightly (see photo) to provide a better fit when attaching to Turbo. Although the Samco is not tight up against it’s preferred marking, there is plenty of material to byte on with the Jubilee clips.
