The A'PEXi ECV (Exhaust Control Valve) allows you to control the loudness of your exhaust sound. The ECV is installed right after the catalytic converter, and adjustment of the valve is done through a cable run from the cockpit to the valve body. All you have to do is slide the lever installed in the car to get the appropriate sound. With the A'PEXi ECV you'll no longer need to get out of the car to fit a detachable silencer into the tail pipe.

The J-STYLE Exhaust Control valve is incorporated into your exhaust system with a lever puller inside your cockpit to adjust the flow rate of your exhaust. This means you can tone down the exhaust noise dramatically over ANY brand of silencers available on the market today period!
