M4 Yamaha R1 2015–2026 Black GP2 Slip-On

The M4 Black GP2 Slip-On for the Yamaha R1 offers a sleek, compact design with a deep, aggressive exhaust tone. Designed to mount directly to the stock catalytic converter, this system enhances the bike’s appearance without requiring major modifications.

Constructed from stainless steel with a durable black ceramic coating, this slip-on delivers excellent heat resistance and a stealth, race-inspired finish that complements the R1’s styling.

Features

  • Slip-on design that mounts to stock catalytic converter
  • Stainless steel construction with black ceramic coating
  • Compact GP2-style canister for aggressive styling
  • Does not remove catalytic converter
  • Enhances exhaust tone and overall appearance
  • Stage 1 Q1 quiet insert pre-installed
  • Stage 2 Q3 quiet insert compatible (sold separately)
  • Optional carbon fiber heat guard available (sold separately)
  • Direct fit for 2015–2026 Yamaha R1 models

Tuning Recommendation: M4 recommends re-flashing the stock ECU to unleash the full performance potential of this system.
