Boost pipe material

Are you welding it? Mine are just painted mild steel. Not bling but easy to fabricate.

One weighs less than the other, one is easier to weld than the other, that's about it

They use aluminum to make heat sinks so it must be a better conductor of heat than stainless.

I was just asking that a few months ago over the honda-tech forums.
The answers were plain and simple....''doesn't matter''
I have the same point of view due to the fact that the engine compartment is very hot anyway so it will not matter if there is alu or stainless or mild steel
If you care about the weight you might search for some 1.5 wall tubing....so that you will not have that much weight.
Anyways....I had alu pipes that got crushed due to the fact that I have t bolt clamps to be ''leak free''
I will go for stainless 63 mm with 1.5mm wall..........and throw away all the alu from my system!

If worried about weight, I've seen carbon fibre used before, great thermal properties too........ but if not worried about weight the weirdest I've seen was soldered copper tube and bends
Carbon fibre is a nifty suggestion; if for no other reason that you can have the bends and fittings exactly where you want them. - What about fibreglass as the next-closest thing?
If it was all about the heat transfer, surely copper would be best? - From Rob's observation about heat sinks; mine is copper (well, copper heat-pipes and core anyway) rather than aluminium... but I do worry it's likely to damage the motherboard having all that weight on it.
- I guess it would make more sense for the intercooler to have copper fins on it than alloy; may not look as pretty though.

Copper, pah! You want silver

It depends; if boost temps > engine bay temps then you want good heat transfer properties to reduce boost temperature. If engine bay temperature > boost temperatures then you want to insulate to prevent heat pick up. Therefore the best silution might require aluminium pre intercooler and stainless post intercooler. Either way I would polish the tube to avoid heat pick through radiation.
Lets go with the ultimate in corrosion resistance; iridium...Copper, pah! You want silver

I'm sure it really doesn't matter either way whether they're alloy or steel, I doubt the weight saving would make a jot of difference to the people on here, It's not like you're F1 drivers looking for a 10th here and there is it ?, If I were to go down the front mount rout again I'd make sure I ceramic coated the manifold/turbo and down pipe and also fitted a turbo blanket before I ever thought about the boost pipes, With those I'd probably wrap them in some of that fancy silver tap to reflect as much radiant heat as possible.
I'd also wrap all the wiring in protective heat sleeves.
