Dealership says they will install a quicksilver exhaust for me about 300 bucks, so that means the majority of the cost is the system itself so I plan on doing it for my 2012 XKR. This has the Active NON-Performance Exhaust and is rather quiet for my taste.

 

Hey Ryan, why not go with an "X-pipe" to replace your resonators and you will have the same exhaust is on your XKR-S.

 

Spires stage 1 is an option as well. I was considering doing that before winter got here and I had to put the car away, now I just decided to build my own.
