COBRA Dual Bungs Pro Chamber Headpipe — Milwaukee Eight, 18 mm bungs, Black – 17-20, 22-24 Touring, 17-20, 22-23 CVO

This head pipe enlarges the PowerPort into a pulse chamber to accelerate exhaust scavenging and deliver the power riders expect.

The round, bulging profile between the heat shields hints at the increased performance beneath.

Includes 18 mm bungs near the heads to accept wideband oxygen sensors, making it ideal for use with modern auto tuners.

Stock Harley-Davidson mufflers are incompatible because of their internal construction; most aftermarket mufflers will fit.

Designed for the Milwaukee Eight motor, it optimizes scavenging and throttle response. 🚀
