Simply getting at the fact that no one makes that I know of a one piece cat-back exhaust for the 2011 Mustang. So axle-backs themselves are not gay. They are one piece of the exhaust you should upgrade. So the question still lies what is a good axle-back and I am sure he will deal with the midpipe next and maybe headers oneday. Then the question is how much before he needs a tune and does he want to void his warranty to do so if it requires a PCM flash. Midpipe and axleback dont usually require one on previous years but neither did a CAI on previous years. I need myself to learn more about the 5.0 system because there seems to be 4 parts to this system. I have removed what appears to be the smaller cats or resonators on the midpipe but there are larger(than I have EVER seen) cats one the pipe above the midpipe. Have not seen any upgrades to replace those as of yet. Any idea on that I'd love to hear.

But I agree with what your saying in that just an axle back itself isn't as worthy as a cat-back upgrade.
