The Performance Front-end (PFE) is an upgraded mouthpiece for your Grasshopper, reducing draw resistance by 80% and adding water pipe compatibility. Now available in Titanium! The PFE allows for a wider range of draw speeds, increases vapor delivery, and reduces mouthpiece heating during long sessions. In addition to being the best front-end for on-the-go use, a 10 to 1 taper provides a perfect seal against your existing glass. Natively designed to fit into a 14mm downstem, the PFE allows you to experience a new level of performance and vapor production.
