I can’t believe how loud these cars are at start up. You literally have to yell to have a convo if standing behind the car. My wife loves it when I leave the house at 6am! 😬

I should take a vid of mine with AA + MPE and valve controller set to open.

It's deafening lol

Add downpipes into the mix and you'll wake the whole neighborhood.
