that stuff looks awsome. ive shot them an email this is exactly what i am using atm, thats why i was quering how hot the pipe would need to take. curious if this pipe/hose would last but ye apart from that the best method looks like to be using a joiner
thought id just update this thread incase someone used search and checked this thread... ...i got some ford bottom hose from supercheap and cut the section out i needed. i also used the stock rubber hose aswell on the recirc side. your bends will prob be different obviously depending on where the outlet of the plumb back is, so just get the bends you need.... with the joiner you can get one from a hardware shop, but everything was closed so i just made my own. from the stock zed recircs i took off the metal pipe from them and cut them and welded them together from both recircs and made my own joiner ...this way both ends are already flared etc...so was an easy way out and ended up being good because its already flared and perfect size etc....
