Installed the Corsa system yesterday along with Eibach pro-kit springs.

Install was pretty straight forward. Most difficult part was removing the factory mufflers from the rear hangers... access is a b*tch.
The Corsa system bolts right up without trouble. Since there are several connections it really helps to have a few extra hands (which I had and am grateful for), but this also helps with getting the alignment just right as you have several points of adjustment to work with.
Since I have Stone White with the Altitude pkg I wanted the mufflers to be black to match the theme. I bead blasted the polished tips and painted the mufflers satin black with high temp paint about a week before.
The sound from the system is perfect. Just right for the family wagon. I have performance cars with exhaust systems MUCH louder, but didn't want anything too aggressive for this vehicle. The drone from the MDS is still there as it was with the factory system, but it's really no worse. The sound is subtle when cruising and not annoying at all. And when you put your foot down it comes alive with a deep aggressive sound. Nothing too crazy, but very good in my opinion. There's a touch of rasp in the higher RPM as you'll hear in Corsa's video, but I expected this and embrace it.
Overall I'm very pleased with the system and believe the Corsa is the right choice for this vehicle.
Thank you to all who have posted their reviews of this system before. It was you that persuaded me to go this route.
Here are a few iphone pics.
