I have a 3" stainlessworks off road x off my 2010 gt500! It bolts up to the 11-12 , only difference in the 11-12 is where your OTA (over the axle pipes) meet the x pipe! Your ota is 2.75" and mine is 2.5" - so you would just have to buy a .25" adapter to connect my x pipe to your OTA or just weld them together ! If you are handy or don't mind throwing an adaptor - I'll cut you a good deal , let me know
