Apexi Exhuast Control Valve (ECV)

The ECV was created as an alternative to the standard silencer typically fitted in the tip of performance exhaust systems to lower the sound output. The ECV (Exhaust Control Valve) is a spring loaded butterfly valve that can be installed to the main piping of an existing exhaust system. The angle of the valve can be modified on the fly from within the cockpit to provide complete control over exhaust decibel output.

SARD T.C.V (Torque Control Valve)

T.C.V. is developed to increase low-range torque and improve torque response at low to mid speeds for race application with a sport-type exhaust system or the straight pipe exhaust system

T.C.V. offers a great flow, similar to that of a straight through muffler, while the valve is open

Noise reducing function of the valve works during idling or running in the low-range

This system is a bolt-on application to exchange with your catalyzer

The System and valve unit are made of durable and heat-resistant stainless steal

SARD Sport Catalyzer

This catalyzer brings out a high cleaning ability that is substantially below the emission control value of safety standard.  This exhaust system is legal and thorough a great flow.

Large cell (200 cpsi) made possible by the noble metal coating which is excellent in purification performance.  This keeps the pressure loss to the minimum.  (Certain vehicle has 180 cpsi) *Cpsi is a number of honeycomb cells per square inch.  Factory standard catalyzer has 400 cpsi.

Comparing to the factory catalyzer, exhaust efficiency is greatly improved which brings out high response and high power.

This catalyzer is made of heat and corrosion resistant SUS304 stainless steel

This catalyzer is equipped with stainless steel heat plate that avoid parts surrounding from adverse effects of the heat.
