On my FMIC the top hose that come off the turbo to the FMIC piping has always been a bit too short and thus the Mikalor clamp regularly needs re-tightening or it slips off and I lose all boost. So I'm trying to order a new hose as it's now damaged and also a longer hose so that I have more excess showing as I have almost none at the moment, if I had a picture I'd show you but the turbo is off the car now.
What I can't figure out is where to measure from? It's a straight reducer and on one side the Inner Diameter (I think, as it's not quite round so hard to measure) is 52mm, the other side is 55mm, the Outer Diameter on one side is 63mm and other side 66mm. It looks like more than 3mm difference when I look at the pipe but it must be right 
It's 72mm long, SFS Performance site
http://www.sfsperformance.co.uk/straight_reducers.asp
gives them in 102mm, so I can cut it down if need be but it gives me plenty of excess, but I can't figure out which one I need
Any tips? Cheers

Well its only 1mm smaller on each side than what you need. The sizes are internal diameters.
Can you measure the turbo/IC diameters?

They are internal diameters then? That's cool that's half my question asked  I can't imagine 1mm making a difference either but I really don't know!
Yeah mate, gonna go do it now

Pics of what I mean, here's how it goes together
Measurements are: Turbo side: 56mm FMIC side: 59mm
So my measurements do all add up :-) but I still dunno what size to buy
