You use silicone couplers to attach it to the radiator and engine.

I went with this option (over Aluminum pipe + silicone couplers) because I didn't want to go back and forth with the various parts to make everything work, because I couldn't find a bending reducer in the sizes I needed, so I'd end up with several couplers/reducers in line with tiny sections of actual pipe... imagine a top radiator hose with 6 or 8 hose clamps holding everything together... no thanks.

I've yet to get the engine started up and get everything up to pressure, but I'm pretty confident that it'll hold.

I'm a little beat down with this exhaust issue... More $$$ more waiting. The difference is large enough that I'm pretty sure I'll need a pair of flex pipes for the thing to be flexible enough to work. fckin annoying.
