Due to our state Cali has very strict law of modified exhaust. I found this as alternative for those who do not want lose their performance of getting a "quiet" restrictive exhaust. I might beconsider getting this, dont know if anyone tested this out before?
Here's description:
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.
