Great sound and quality. Would by again. If you want more quite sound go with the 24 inch.

Exactly what I wanted and expected!

For my 2014 F150 5.0 I ordered the Magnaflow P/N 53070 with 3 inch centered inlet and 3 inch offset outlet, 5X11X22 inches. I had a local exhaust shop weld it up and they had to add a six inch extension as the huge stocker was longer. With only a few hundred miles on the muffler, it already sounds perfect! I wanted a not-too-loud rumble when the engine had to work, but otherwise pleasant. I got just that!

I bought #12589 because this Magnaflow muffler is Stainless Steel, has a LIFETIME Warranty for the original purchaser and is known to be quiet 90% of the time which I can say is very accurate. If you want something extremely close to stock noise levels when idling or cruising this is the muffler for you. The only time you hear it is when you are hard on the gas or the rpms sit between 1700 - 2200 while cruising and even then it's a nice mellow tone that is not deafening. Very happy with it.!!

Best Muffler....Period!

The Magnaflow Performance Mufflers have the best appearance, sound and quality of any muffler available. I've run them on numerous vehicles and will always be my first choice.

Exactly what I was looking for.

Wanted to add a little bit of an exhaust sound to my Expedition without getting the drone that my dual exhaust F150 has. This Magnaflow muffler is the longest one they make to ensure it is quiet on the highway. It has a great V-8 growl on startup and acceleration with no baffled echo like my other vehicle does with it's flowmaster. Top it off with getting the muffler on sale, and I'm a new Magnaflow fan.

Super quiet

I ordered a 22 inch magnaflow fitting the muffler dimention that I took off. I was very suprised that how quiet the muffler is considering that it is 3 inch diameter inside all the way thru. Perhaps with some age it will become louder but for now it is a little dissapointing. Overall I am happy with the quality and like having a lifetime warranty.
