I decided to go 35% all around. Thanks to all for the help.

Driving home I do.like the purr of this can a lot. But, the sound of my corsa exhaust, mopar headers and CAI blew away any mustang. I wish I had recorded the sound of the engine starting after the car was outside overnight during a Chicago winter night. So badass!

In regards to dropping it I would be paranoid about speed bumps and curbs.

 

Very nice - congrats! I also have a 2012 G37xS Coupe. I added the midnight black grille and the rear spoiler and I am very pleased with the way booth look.
