I am interested in the same. I have contacted Mike at 5 star for his recommendation on a CAI - Tuner package then I would assume the exhaust is just personal preference? Magnaflow, Borla or Flowmaster?
I will be installing a Magnaflow before I buy the Tuner and Intake, I am just wondering if they can make a 93 octane tune that would consider the exhaust that I go with,
