Trying to find some boost pipes in polished aluminium or stainless, where’s the best place to buy them from? Also I noticed there’s two type of radiator bottom hose (big L shape) one set is chrome with 2 silicone sleeves and the is just a big silicone hose, has anyone fitted either? Does the chrome pipe rattle about? Not sure what keeps it in place. 

The hard radiator lower pipe was designed due to a few reports of the pipe collapsing under vacuum “upstream” from the water pump. I’m not sure how common this phenomenon actually is but I fitted the Z1 hard pipe kit in black with black sleeves. It can be secured in the same way as the stock hose.

Thanks. It is the Z1 kit I was looking at. 

Just jump on the Z1 or CZP site in the US there isn’t going to be much option other than shopping abroad. Get the hard pipe version for coolant and same for the boost pipes which I assume you just mean the 4 on top at the front. Get hard pipe version again and a quality brand as they can be made poorly otherwise.
