Core Product Specifications

  • Material Construction: Fabricated entirely from high-grade 304 Stainless Steel tubing.
  • Exterior Treatment: Finished in a specialized, high-temperature matte black ceramic coating that provides excellent thermal management, prevents raw steel corrosion, and offers a sleek, stealthy look.
  • Muffler Configuration: Employs a low-slung, ultra-compact Dual Silencer Straight-Through configuration tucked tightly under the frame rails for an aggressive, shorty appearance.
  • Performance Gain: Features engineered mandrel-bent primaries that yield an increase of roughly +5 Horsepower over the stock catalytic assembly, creating smoother throttle transitions across the rev range.
  • Mass Reduction: Eliminates the heavily baffled stock under-body catalytic converter box, dropping the vehicle's net weight by roughly 6 lbs (2.72 kg).
Fitment & Installation Details

  • Cross-Model Compatibility: Fits both the 2022–2026+ Yamaha XSR900 and the 2021–2026+ Yamaha MT-09 / SP variants due to shared engine and mounting architectures.
  • Hardware Integration: The kit includes a dedicated O2 sensor wire extension harness, allowing you to route the factory oxygen sensor directly to the relocated bung on the M4 midpipe without cutting wires.
  • Tuning Recommendation: While the system physically bolts onto a stock bike, an ECU re-flash or fuel map adjustment is recommended to correct the lean air/fuel mixture caused by deleting the stock catalytic converter.
