This Adapter Kit allows the installation of our Hayabusa Alien Head, CT Meg, CT Single, Penta-Carbon, ShortMeg, StreetMeg, and TiWinder full exhaust systems to mount and function properly on the Euro 5 Compliant Generation 3 Hayabusa (2022).

4-2-1 Sidewinder compatible when combined with a user-installed O2 Sensor Bung & Plug Kit. The CT Dual is not compatible with the 2022 Hayabusa.

The Brock’s Performance Gen 2 to Gen 3 Hayabusa Full Exhaust Adapter Kit Includes:

  • (1x) Plug and Play Oxygen Sensor Harness
  • (1x) 18mm to 12mm Aluminum Bung Adapter
  • (1x) 4 Pack of Graphite Exhaust Gaskets
  • (1x) Radiator Spacer Kit w/ Stainless hardware
  • (1x) Permatex Anti-Seize Lubricant

Most Brock’s Performance Gen 2 exhausts will physically fit the Gen 3 Hayabusa, but the Gen 3 will throw O2 sensor codes unless the Gen 2 aftermarket exhaust is equipped with provisions to allow the installation and continued functioning of the new dual 12mm O2 sensors used on the Gen 3. Since most Gen 2 exhausts do not have these provisions, Brock’s Performance has developed this kit to prevent error codes and the associated poor performance when codes (or pending codes) are thrown by the Gen 3.

We also include convenience items to perfect the physical fitment of a Gen 2 full exhaust to the Gen 3, such as Gen 2 exhaust gaskets (Gen 3 exhaust gaskets are not reusable), radiator/oil cooler spacers, and corrosion-free stainless steel mounting hardware. Although developed specifically to function with Brock’s Performance Full Exhaust Systems, this kit will also work with most aftermarket Gen 2 Hayabusa full exhausts that contain an 18mm 02 bung typically used for data logging air-fuel ratios. Please note the 18mm bung will no longer be available to measure air-fuel ratios using aftermarket data loggers.

Note: When installing an Alien Head, ShortMeg, or Penta-Carbon exhaust system using this kit, the muffler mounting bracket must be modified to provide clearance for the rear brake lever (follow link for instructions).

    Converts perfectly

    Posted by TIM L on Nov 26th 2021

    This kit gives you exactly what you need to convert the gen2 exhaust to a gen 3, minus one o2 sensor. Have ridden then bike without the second o2 sensor and have had no issues so far. Will say the new gaskets that are included are a tight fit but are definitely better quality then what comes with the bike. Also included are spacers for the radiator so that you can give the radiator a little room away from the now slightly bigger headers. Make sure to pick this up if you are buying a gen 2 exhaust for your gen 3.
