Aerosol-generating system with low resistance to draw and improved flavour delivery

An aerosol-generating system, comprising:

• an aerosol-generating article configured to produce an inhalable aerosol upon heating, the aerosol-generating article extending from a mouth end to a distal end and comprising:
• an aerosol-generating element, and
• a downstream section located downstream of the aerosol-generating element, the downstream section extending from a downstream end of the aerosol-generating element to the mouth end of the aerosol-generating article,
• wherein the downstream section comprises a hollow tubular element and a resistance-to-draw of the downstream section is less than about 10 mm H2O;
• and
• an aerosol-generating device having a distal end and a mouth end, the aerosol-generating device comprising:
• a body extending from the distal end to the mouth end, the body defining a device cavity configured to removably receive the aerosol-generating article at the mouth end of the device, and
• a heater configured to heat the aerosol-generating element when the aerosol-generating article is received within the device cavity,
• wherein the heater is further configured to externally heat the aerosol-generating article when received within the aerosol-generating device.
