Key Technical Specifications
- System Design: High-flow 4-into-1 crossover setup optimized with hydroformed collector segments.
- Road Legality: Strictly not street legal. Installing these decatalysed racing headers bypasses the bike's emissions controls and instantly voids any road-homologation or EC/ECE type approvals of your existing slip-on muffler.
- Weight Reduction: Cuts an impressive 5.1 kg from the total system weight by eliminating the heavy, bulky factory underbelly catalytic converter and chamber.
- Performance Maximisation: When combined with a matching slip-on muffler and proper fuel tracking, it unlocks an additional 3.2 hp (2.4 kW) at 11,550 rpm and 6.9 Nm of torque at 9,050 rpm.
Critical Fitment & Mapping Realities
- ECU Flashing Mandatory: Running an unrestricted straight-through 4-into-1 pipe on the sensitive 2017–2020 ride-by-wire R6 engine safely requires a matching map. Bypassing the stock collector sensor feedback will severely lean out your air-to-fuel ratios. You must use a custom ECU flash or fuel management mapping (such as specialized Dynojet setups) to ensure proper engine durability and eliminate flat spots.
- Muffler Connection: The exit pipe diameter links natively with Akrapovič Slip-On Line mufflers (such as the Megaphone, Carbon, or Titanium configurations)
