At DMG Motorsports, we present the Yoshimura R-77 Premium Muffler Repack Kit (REPACK-R77-ADV) — the genuine OEM solution for restoring your R-77 muffler back to peak performance. Over time, exhaust packing breaks down and gets dirty, robbing your bike of power and changing the exhaust note. This factory repack kit gives you everything needed to refresh your R-77 muffler with fresh, premium packing material so your exhaust performs the way it was engineered to.

Features:

• Genuine Yoshimura premium packing material engineered specifically for R-77 muffler systems
• Complete kit includes premium packing, rivets, rivet bands, an R-77 name badge, and repack instructions
• Recommended service interval: Yoshimura advises repacking every 7,000–10,000 miles to maintain optimal performance
• Restores airflow that becomes restricted by dirty, worn packing, helping recover lost power
• Improves and refreshes the exhaust sound that fades as packing degrades
• Fits R-77 muffler systems only (not compatible with R-77M mufflers)
• Designed for motorcycles as delivered from the factory; compatibility may vary with non-stock accessories
• Backed by Yoshimura's decades of exhaust research and development expertise
