I did replace the factory muffler with the AP. It sounded mostly the same but the AP muffler was of poor construction. The pipe used on the inlet was smaller diameter than on the factory muffler, and it wasn't mandrel bent. The AP looked cheap and restrictive. Shortly after installing the AP, the factory resonator blew out internally and I regretted not purchasing a complete catback from the start.I know this is an ancient thread, but did you ever replace the factory muffler with the AP? Did it sound the same? Has it rotted out yet? I'm deciding if I really need the Ford $400 replacement. My experience with Walker stainless aftermarket is that they last 2 years. How'd you make out?
If any component of your factory catback is bad I recommend replacing it entirely with an aftermarket catback-not AP.
Factory muffler vs AP.
