Electric Exhaust Catback Cutout Valve Y Pipe E-Cut Out Valve System

Where would I go about installing this at on my Silverado, before the muffler? After the muffler? And does it work on stock exhaust system??

I would put it as immediately after your Y pipe merge as possible for more volume output after the converters and before any resonators that may be in the intermediate pipe.
