HKS 2 Stage Exhaust System, 45th Anniversary - Nissan GT-R R35

When the valve is closed, the large capacity silencer and dual 60mm long exhaust pipes maintain the silence. Black exhaust tips provide high quality with visual presence. Gold HKS logo gives more premium appearance.

As the tuning level is advanced, implementing “silence” and “high power” together may be difficult. But, with 2sx Muffler, it is possible by the switchable valve equipped with this exhaust system. The valve controls the exhaust path depending on the engine RPM so the exhaust system can withstand high power maintaining silence at low speed.

This valve makes two exhaust paths. The valve is operated by an electric motor. The valve is connected to the electric motor with a control cable to transmit power. The electric motor is automatically controlled by a controller.

*The controller is a purpose-built. The engine RPM signal and speed signal are required to connect to the controller. The valve opens and closes automatically according to the engine RPM and speed. This exhaust system with the switchable valve can implement “silence” and “high power” together.
