I can vouch for universal e-bay intercooling pipe kits, and you can get a LOT for your coin even shipped from the USA. I've bought two, one in 2.5" and one in 3", and will have a fair bit of excess if anyone is interested in some sort of a deal. No rush, just stuff I won't use.

The e-bay tubing is a little rough here and there, arrives with the odd ding, but the bends and silicon parts are fine, certainly great compared to individual prices at supercheap etc.
