You don't have to have that to fit the I/C, could just make up a connector from silicon parts.
if you really wanted a solid pipe then it'd probably be best to find a friendly local fabrication shop and get them to knock something up for you. Doubt you'll find an old PSD one for sale as they only made a couple as far as I know.
I can't sell you mine because it's been modified to fit with my bigger IC and turbo setup.
