Oh and just a note for any of you out there this might affect:

We had to trim a little bit of rear faux diffusor to fit my Amuse Dual R1 Titan. No big deal and its on the inside of the bumper so its not something you see, just a note that the clearance is tight between the cans and the rear (some of it could be because my exhaust mounting points were a little bit jacked up from a fender bender but I still think you'd need to trim even on a brand spanking new S if you're running that exhaust).

The bumper would go on fine, but it was too close to comfort for me and I didn't want anything melting

 

Awesome, thanks for the feedback to both of you!
