Great Sound, Tough Install
Background and general satisfaction: I purchased this X-Pipe mainly because I wanted to make my Mustang louder. These pipes are loud. I am using the Borla S-type axle-back which have a good sound on their own, but the BBK x-pipe amplifies that sound to the max. 3000 RPM lets out the most loud, obnoxious, disgusting, raspy tone ever. People driving behind me have switched lanes because of it. I love it.
Fit: The pipes fit, there's no doubt about that. I did notice that after installation my mufflers shifted inward a bit and now do not sit centered in the rear valence. I'm okay with this, and it can possibly be fixed through some adjustments.
Installation: Somewhat difficult without a lift and the proper tools. I used a jack in my driveway with a friend's help. Removal and installation of the catalytic converters required a ridiculous amount of wrench extensions in every which way. My '13 has a lot of miles on it, and the bolts were heat-worn and rusted, and needed a lot of strength. We ended up stripping out the exhaust manifold flange bolt and I had to go to my local Ford dealer to buy a new one for $12. This did the trick. I drove the new pipe for 2-3 weeks and begun to hear an exhaust leak, almost as if there was a baseball card in a bicycle wheel. Tick tick tick tick and it was related to RPM. Decided to bring it to my local mechanic. The driver's side catalytic converter came loose and needed to be tightened. I attribute this to the difficulty reaching those bolts and would recommend this install be done by someone with the appropriate power tools, or a mechanic.
Conclusion: I love this pipe. Any problems I had with it are all attributed to mistakes made by me during the installation. That being said, the installation isn't easy based on the difficulty getting to those exhaust manifold flange bolts. I wouldn't go back to the stock pipe if you paid me, though.
