Designed for Harley-Davidson® riders who want a balance of bolt-on performance and budget-friendly customization, these head pipes provide low-end torque gains while allowing you to reuse your stock heat shields—saving money without sacrificing results.

What is a 2-1-2 Head Pipe System?

A 2-1-2 system routes exhaust from both cylinders into a merged collector before splitting again into two outlets. This configuration is ideal for riders who want strong low-end torque, smooth throttle response, and a cleaner installation that mimics the stock appearance.
