That's what I always assumed. None of my relays use their full bandwidth, although they aren't exits either. Still, the exits may not be a limiting factor anymore. According to Tor Metrics, the network has been carrying ~700 MB/s in recent weeks. Each circuit includes three nodes, so the actual amount of unique data is 1/3 of that**, or ~233 MB/s, which needs to find its way to an exit. I just pulled a CSV of relay information from Blutmagie and summed the actual (not advertised) bandwidth of the exits, which is 298 MB/s. So, they're already carrying more bandwidth than they need to in order to handle all the unique data (the reason it's more is because exits also carry middle and entry bandwidth). ** While the network carries 700 MB/s total, it's the same data at different nodes, at different times, so the exits only need to be able to handle 1/3 of the data, as long as they are 1/3 of the nodes on a circuit.
