I believe that is the DNA Motoring catback system. Appears to be a stainless 2.25" pipe that deletes the muffler. It's available on Amazon as well.

I too would love to know what others think of this exhaust. It looks nice but I would love to know what it sounds like.

It sounds mild in that video, which is good. I don't want to annoy my neighbors and/or get tired of non-stop rumble myself.

What about emissions testing? Isn't our catalytic converter hidden inside the muffler?

I have this installed. Yes its a DNA motoring exhaust. They call it a catback system but it allows the resonator (scubba tabk) to stay on the car still. This is basically a 2 muffler delete and 2.25in larger piping upgrade. The sound is very mild and sounds similar to a stick 350z/G35 exhaust which I love. The video on yotube actually sounds louder because the recorder is right next to the exhaust. I did feel a slight upgrade to power since the car went from slow to a little bit faster than slow lol. I installed this by putting my passenger side on jacks and squeezed under neath. Because of my lack of space it took longer than it should (1.5 hrs).

Smog should be fine. The catalytic converter is up front right after the headers. The resonator even stays. This exhaust starts from the center of the car after the scubba tank (resonator).

How is the sound inside the car? Any drone on the highway?

You can barely hear it, not annoying at all. Sometimes I wish it was louder but it has a nice natural sound. On the highway its not disruptive. Barely noticeable on the highway.
