M4 Yamaha R1 2015–2026 Street Slayer Half System

The M4 Street Slayer Half System for the Yamaha R1 is engineered for riders seeking maximum weight savings, aggressive sound, and race-level performance. Featuring a catalytic converter eliminator and full titanium construction, this system dramatically improves exhaust flow and power delivery.

Paired with the MC36 carbon fiber canister, this setup delivers a premium race-inspired look while significantly reducing overall weight compared to the stock system.

Features

  • Half system with catalytic converter eliminator for maximum performance
  • All titanium tubing for extreme weight savings and durability
  • MC36 carbon fiber canister for aggressive, race-inspired styling
  • Saves approximately 14.5 lbs compared to stock system
  • Improves exhaust flow, throttle response, and sound
  • Q7 quiet insert compatible (sold separately)
  • Direct fit for 2015–2026 Yamaha R1 models

Important Notes:

This system may drag during track use at heavy lean angles. ECU re-flash is required when removing the catalytic converter on 2015–2026 Yamaha R1 models.

Note: Does not meet emission requirements for street or highway use.
