GY6 Raw ProBld Yoshimura Exhaust System

The Details ⚙️

Most GY6 exhaust setups cheap out where it matters — especially the header. You’ll see high-end mufflers paired with thin, one-piece headers that discolor, crack, and kill the whole setup.

This ProBld Yoshimura exhaust system fixes that. Built specifically for Honda Ruckus and Icebear Maddog GY6 builds, it pairs the proven Yoshimura RS2 muffler with a header that actually matches the quality.

You’re getting a polished, TIG-welded, 2-piece stainless header with an integrated wideband O2 bung, a reinforced triangle hanger, and a clean heel guard — all designed to hold up under real use.

No shortcuts. No weak points. Just a proper exhaust 🔥
