A Valvetronic system is a variable valve system which allow exhaust branched into two paths. This technology has been used on Ferrari / Lamborghini supercars for more than 10 year and is now available to be added on many aftermarket exhaust systems. 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.

The performance of exhaust system is a perpetual battle between torque and horsepower.  A nice torque output will decrease horsepower, but to maximize horsepower output torque performance will inevitably be sacrificed under low speeds.  You will get unprecedented driving pleasure never felt before, including the horsepower, torque, and Formula 1 sound.
