This chillum from Grav Labs gives some clean hits due to it's Helix Venturi chamber. The Helix chamber is funnel shaped and has tiny holes angled up in the same direction to guide airflow. Due to the design, the smoke swirls into a tornado as it goes through the chamber.
Besides looking cool, the effect also cools down your smoke, slows the burning (which conserves your material) and creates a smooth hit.
A Helix logo crosses the chillum and to hold this pipe easier, there is a colored nub.
