Not trying to hijack this thread, but WEIRD, on that picture of the bottom of the BOSS you posted, I noticed one of the resonators (I think it is the resonator?!?), looks crushed (Driver's side, top in pic about 3/4 the way back right as the exhaust goes through the gas tank tunnell?!?). I noticed the same thing on my 2013 when I was installing my flowmaster outlaws and at that point was wondering if my car had bottomed out when it was pulled off the truck at the dealership. Now that I see the same thing on that BOSS pic, it has me wondering why they are like that? Anyone else notice this on their 2013 and have any insight as to why one of them appears flattened??

I had the GT500s mufflers on my 2011 6MT 'vert, then removed them and put the 2011 back to stock for selling it when I ordered my 2012 6AT. May have been my imagination, but to me (and my wife) my 2012 6AT sounded "better" than my 2011 6MT did, stock-for-stock. And when I installed the GT500 mufflers on my 2012 6AT it didn't seem to be as much of an "improvement" as when I installed the GT500 axel-backs on my 2011.
Was wondering if the mufflers were improved for sound between 2011 and 2012, and almost started a thread on the subject....

No they aren't the same, automatic has mufflers with a different tip, the ones with the small pipe inside the tip.
Early 2011 through end of Job 1 had no resonators on manual equipped cars, later ones did and all 2012-2013 cars do.
And sure you can remove the resonators and replace them with a straight pipe, will increase the burble and pop on deceleration might make it slightly louder.

I believe all cars have the resonators. Those are in place to attenuate a single frequency. Typically it's the frequency that adds to the dreaded drone. They are straight-thru and really do not pose much of a flow restriction. Even where you see the dented area does not get into where the exhaust flows. because there is a straight pipe that passes thru the center of the resonators.
Now, the mufflers are in fact different between automatic and manual cars. I just got finished swapping my mufflers on my car with GT500 axle-backs. I noticed that the stock ones I removed had stickers that had "MAN" on them. That means they were specific to manual trans to give a little different sound.

amen to that.

I can confirm that my 2011 Job 2 Performance Package V6 did NOT have resonators.
