Great sound with this muffler. Did the flapper delete as well and this welded right in. I should have bought the offset (12259 IIRC) but it was not in stock and the installer had to put in a small piece of pipe for the flapper delete so a couple of small bends and it welded right up. Took it back into the dealer for some service work and no less than 5 people asked if that was the factory sound... Heck no.. Magnaflow sound, all loved it on the 5.3 V8. No Drone and barely noticeable in cab.

Good but not great

I recently installed this muffler on my F150 5.0L. The sound was not as aggressive I was expecting. This was my first time using a Magnaflow. I have always had Flowmaster or Flo-Pro in the past. The sound is just barely louder/more aggressive than the stock muffler. I will probably end up switching it out with something else.

Sounds great on my 2014 F150 5.0L

You can hear it when on the gas but quiet when on the highway.
