Hello everyone
I am seeking some advice from experts.
I found this VOD and the exhaust system on VOD is switchable between normal and sport mode by a button from inside of car.
The VOD shows both normal and sport mode constantly changing. You can tell by the exhaust note.
I would like to know what you guys think.
Also, what do you guys think about the drones and other issues involved with this exhaust?
The VOD may going to take a while to load, however, patience can payoff.
Hope I can get some good response.

It's obvious that car has an electric exhaust cut out. I will eventually do the same to my car when I do a quad exhaust using the stock muffler for quiet times and a straight pipe or straight through muffler for the loud times.
