·       Dyno proven gains of 30+ horsepower as measured internally at HKS and at external facilities

Debuted at SEMA 2019 on HKS stunning demo car, this dual muffler exhaust system for the 2019 Toyota Supra sounds as good as it looks. This system retains the valved exhaust system present from the factory and reuses the OEM actuator motor, allowing you to control the sound of your Supra just like you would with the factory system. This system makes the most of the B58, allowing the turbo straight six to sing its siren song free of restriction, yielding dyno-proven gains of over 30 wheel horsepower. Given the high performance of BMW-built turbocharged inline sixes – N54, N55, S55 and now B58, this is an excellent starting point for any high power A90 Supra build.
