how stretchy is silicone hose?

Simple question: will a 57mm silicone hose fit over a 60mm O/D pipe?

Silicon hose doesn't stretch much compared to rubber hose. Rubber hoses you can heat up and it becomes more pliable. I think you'll struggle with a 3mm difference and silicon hose...

32mm silicone hose fits onto 34mm outlets on my engine, so I reckon you should be OK. Don't blame me if it's not though

In my experience, yes with a bit of a push, the last bit I did to the tintop boost hoses was fitting a 51mm ID elbow over a 53mm OD pipe I turned up, but I also put a 2mm lip on the edge to stop it blowing off and managed to get the pipe over that too

(It was samco 4 ply, others can be even more stretchy)

Yes but you have to work it. I have found rubber ones harder to stretch over pipes, but maybe the size difference was just too big.

Think good rubber hoses get stuck to the surface faster then silicone, silicone tends to slide easier

Thanks for the info guys, looks like its a go then

I'm putting four of these in my airbox to connect to my throttle bodies:
