The Ford Racing cat back/axle back is the Borla. All that is different is the tips either say Borla or Ford Racing.
The factory exhaust looks horrible after a single winter, but it is all surface corrosion and it will take a long time for it to be an actual problem. A little steel wool would clear up most of the corrosion. After having a winter with the Borla and a winter with the stock exhaust, I can say the Borla one looked far better in terms of surface corrosion. The muffler, tips, and piping looks really good on the Borla. Is that enough to warrant spending the money? Not for me. I got an amazing deal on the Borla for my 2011, and if I had a similar deal that good for my ST, I would consider it. Removing the stock resonator on the ST seems like a great cost option, knowing the cat back versus stock isn't that big of a performance gain. I would like better looking exhaust tips, but the current offerings of cat backs/axle backs with tips that I like are more than I want to spend for something with an overall minimal gain. Looking at the price of the FRPP/Borla axle back, I would rather spend a little more and get the FSWerks complete cat-back. I can't imagine the axle back with stock resonator is going to be that much different than stock. Once you add up the cost of the axle back, installation, and removing the resonator, you are at the point where the FSWerks is a better option. It is really tough to justify the cost of throwing out a really decent performing exhaust for just sound and tip design. Even harder to justify the axle back option since it is still expensive and retains the stock resonator.
