There's no way a CX-5 will beat even a V6 Mustang. Second, you'll love the gears. I was quoted around $300 for install if I ever wanted to do it. My 3.31s do just great though.
I know a CX-5 won't beat a V6 Mustang, after 1st gear it has no power. From a standstill it just feels faster till the Mustang hits 3500 RPM's due to the 2.73's. Thankfully that will be fixed Monday, should have done more rresearch and gotten the performance package, but my wife fell in love with the grabber blue and matte black stripe.
Going to be an interesting drag race now, the Mustang will have the torque advantage over my Camaro, but once the Vortech spools up can the Camaro catch the Mustang? Going to be some awesome GoPro vids.
