Anyone familiar with this exhaust bypass?

[TRP]

Does it add power? I couldn't say. They cut out the exhaust before the muffler. Make noise for the sake of making noise? I guess that's one way of looking at it.

The controller is a key fob. The valves are opened and closed via a control box which opens a valve that is tapped into a line off the manifold.

I like them better than an aftermarket system. YMMV.
