The APEXi Exhaust Control Valve
![](./images/smilies/spacer.gif)
(ECV) controls the amount of exhaust flow from an exhaust muffler and thus varies the loudness of the exhaust volume.
![](./images/smilies/spacer.gif)
The ECV is installed after the catalytic converter in a vehicle's exhaust system.
![](./images/smilies/spacer.gif)
It can easily reduce the exhaust loudness level by a maximum of 10dB by varying the butterfly valve in the ECV.

With the ECV, you can now maximize a high performance car potential; be it driving in urban areas, at night, or in areas with strict sound emission laws, just by varying the butterfly valve opening in the ECV.

All these adjustments can be done in the cockpit on the fly by wire controls of the ECV.

The butterfly valve can be controlled in real time while driving either with the valve in fully opened, fully closed, or partially opened position.

Before the invention of the APEXi ECV, exhaust sound levels could only be controlled by using different inner silencers in an exhaust muffler.

These inner silencers require vehicle down time to install, dismantle, and re-install to achieve similar performance levels of the ECV.

The ECV replaces the connecting flange on the piping
![](./images/smilies/spacer.gif)
(after the catalytic converter) that connects to the catalytic converter.

The wire that controls the butterfly valve on the ECV runs via the heat sensor cabling
![](./images/smilies/spacer.gif)
(as in NISSAN vehicles) and through an opening from the vehicle's under carriage to the interior of the vehicle where it terminates at the valve control lever switch in the cockpit

(Easily accessible by the driver).

Minor drilling

& modification on exhaust piping after the catalytic converter might be required on other vehicle makes

(e.g.

TOYOTA vehicles).

Please select your Pipe or flange size.
![](./images/smilies/spacer.gif)
Either is suitable depending upon your application.
![](./images/smilies/spacer.gif)
The flange type will fit as a replacement flange that connects to the catalytic converter
![](./images/smilies/spacer.gif)
- just choose your flange size.
![](./images/smilies/spacer.gif)
The pipe type will fit AFTER your existing flange by creating a cut and weld in between the pipe and is specified in the size of the pipe you are installing into.
