Install was a breeze.
Jacked up the car and crawled under to undo the connectors and to bolt on the controller to one of the brackets.
I forgot to bring the wire coat hanger, but it wasn't necessary.
Just plug the two connectors for the passenger's side and feed them through the heat shield. Came out the other side in like 5 seconds.

Mine is set to Factory (default) - Open (when on).
I always start the car (cold startup), hit the M1 button then hear the exhaust get louder, and then hit the Homelink button to activate the VSC and I'd say it gets equally louder when I hit the M1 button.
Exhaust note gets noticeably deeper in tone.
It's not night and day, but I think you'll be satisfied with the increase in volume.
Thanks, glad to hear! I bought the one where the flaps are open unless activated. Yeah I noticed hitting m1 is much nicer on the ears. Still needs more but it's an audible difference and I'll take it for now lol. Wonder why m2 doesn't do that even though I have the exhaust setting the same for both.
