Right currently fitting my sillicone pipe and it's a really tight fit and rubbing/ sittin on a solid metal pipe , and how the hell do you get a jubilee or something on the turbo end ???

either undo the clip and wrap around and do up again or put clip on before putting onto turbo,

I've got the clip o now but it just seems like the pipe is far to tight like there's a lot of places it could rub etc are they just generally this tighter fit ?

there is a clip holding the metal pipe steady to the block, I had to remove this and actually leave it off.
