Gen 2 to Gen 3 Hayabusa Full Exhaust Adapter Kit

(No reviews yet) Write a Review

This Adapter Kit allows the installation of our Hayabusa Alien Head, CT Series, 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 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

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 the 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 G3, 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 all Brock’s Performance Full Exhaust Systems, this kit will also work with most 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.
