Hi Jeff,
I just got my XF in March. I am not looking to do any Mods to it. Just looking for a nice sound. At this point I have done a muffler delete. Didn't really like that and had a Cherry Bomb muffler added just after the rear cats. This is acceptable to me but may look into a Borla or Magnaflow system down the road. Right now I am good. hope you get what you are striving for. GOOD LUCK.
