Thank you for that. I prefer to upgrade to a 3 inch version, plus I have prior experience with Borla catbacks on my previous mustang. Nowadays, it seems that most aftermarket exhaust company's are only making 3 inch pipes for the 11-14 GT. I suppose I could just get the 3 inch version and get a local shop to cut off the extra inch.
