That is true however if the conditions that caused it to get hot still exist, the alluminum is going to transfer that heat into the intake charge as opposed the the SS which does not exchange heat in the same fasion. If you are talking about running at the track, between rounds, there is adequate time to cool SS piping and the likelyhood of it heatsoaking is less. It takes longer to heat soak the pipe and even after it is hot, it still will not transfer that heat into the intake charge more than alluminum otherwise intercooler cores and radiators would be made from SS. Alluminum is much less expensive to manufacture which is why larger companies like APC and Injen make intakes from alluminum, they take manufacturing costs into consideration considering volume of parts and marketing to the masses. That and polishing SS is more expensive and you don't have the options to anodize in lots of pretty colors that the majority of our markets seem to like over performance even. Buschur's intake pipe is SS as well for the same reason's I mention, not for ease of manufacture, rather because it is better. As far as intake manifolds being made from SS, they can be, and it would be effective but the fabrication required to make a decent manifold that didn't look like ass would be cost prohibutive to too many customers and beyond the capabilities of most shops. In either material, I would want the intake insulated from the head to stop heat transfer to keep it from maintaining a higher temperature. I have actually considered making my intake out of SS because I don't have to worry about the cost of manufacture and trying to make the price attractive enough to sell to the public.
