Post about intercom/sound system is going the expensive route. Look in motorcycle accessories. Chatterbox works fine, and not much over $50.
I assume you're talking used Chatterbox prices? Are there adapter cords that will allow it to easily interface with non-helmet headsets as well? I would still have to buy two of everything to make it work, where I would only need one aviation intercom and one more aviation headset, that could both probably be purchased used for about the same price or not much more. I would expect the aviation setup to provide better (too much?) noise suppression, might provide more effective open cockpit communication, and just for the fun of it would provide a more period-correct look/feel. On the other hand, the modified motorcycle setup could be used both with and without helmets, on the track and on the street respectively, and would allow phone connectivity too...Luckily this won't be a problem for at least a couple of years.
General Note: Wearing hearing protection while driving these roadsters may actually be illegal, depending on where you are driving and what method you're using.
