Does anyone have any experience with installing the Magnaflow Street axle backs on a 2013 V6 Mustang? On the American Muscle site it's listed to only fit 11-12 V6 Mustangs, but their demo video shows it installed on a 2013. Also in the Q&A section on their site one of the AM reps responds that it doesn't fit on the 2013, and that you need to buy the cat back specifically designed to fit the 2013. Almost all the other axle backs that I've seen say they fit 11-13, but not this one. Anyone have any definitive answers on why this would be the case? I'm trying to decide if I can buy the axle back and save a little money, or if I need to buy the cat back. I'm considering purchasing one of these soon since AutoAnything has a 15% off black friday sale until 11/25. There is an $89 difference in price which isn't a huge deal, but I think these things are overpriced as it is so I'd like to get by as cheap as possible.
