so everybody knows the 2010s got the shit end of the stick as far as axle backs go. i was curious if all i would need to do is purchase 2011+ cat backs to be able to run the 2011+ axle backs or do i need new hangers and a bunch of other stuff.

11+ over axle pipes won't bolt right up to your Xpipe since they are different size pipes. 07-10 use 2.5" and 11+ are 2.75". Also the hangers are completely different on the axle backs. You need to purchase new mounting brackets as well. I'm running a 2013 Hpipe, over axle pipes and mufflers on my 2010. Of course, I changed out my whole rear end to fit the 13 tail lights and mufflers.

danm sounds pricy. oh well i suppose i will just have to have axle backs modified if i find the ones i really want. its so hard to find a good deal on some 2010 axle backs. i already have long tube headers for my car. so i really dont wanna mix it up to much( i havent installed the long tubes yet)
