hi, anyone know the exact sizes of the various couplers in a 951 engine bay? hard pipes, expansion tank pipes, etc etc. This will save me taking mine off to measure. (I assume it is the internal diameter that is measured?)

FYI - found the hard pipe sizes
Two 2-1/4" Straight Couplers for intercooler connections
One 2-1/4" - 2-3/4" Reducer for throttle body connection
One 2-1/4" - 2" Reducer Elbow for turbo connection
I bought a set through ebay for $23 by buying the parts individually and got free shipping. A lot cheeper than other sources, I will feedback on quality

If those don't end up working out for you, Sean (azmi951 here on Rennlist) had a bunch of sets of Tial silicone boost hoses made up with good clamps. It looks awesome and is waaaaay better than the stock crap. He's got various colors -- blue, black, red (I think he's got a set left)...
