I am bumping this thread for some input on this.
I have the stock axle backs off of my 13 5.0 GT, and I was wondering if they would bolt up to my wife's '14 3.7.
From post 5 and 6, it sounds like the inlets are different sizes, and I will need to take them to a muffler shop to get them to fit? I just didn't want to crawl under the car and take the stock 3.7 mufflers off only to find the ones from my GT don't fit.
