FS: Magnaflow 12589 Stainless Muffler Like New

[Vulcan762]

For sale is a practically brand new Magnaflow 12589 Stainless Oval Center / Offset Straight Through Muffler. I installed it and two weeks later put on a cat back system. Paid $146 for it and would like to get $75. Pics are of the actual item for sale. This muffler is a direct replacement for the factory muffler on a 2014 GMC Sierra 1500 5.3L but fits a wide range of applications. Just measure the length of your existing muffler and see if you have 22" of space. Sounds a little more throaty with a smooth deep tone. I'm located just West of Tampa Florida but can meet up within a reasonable distance.

If the tip will fit a 6.2L and can be shipped, I'd love to buy it.

I won't be able to measure my 2017 6.2L exhaust diameter until January 4th (traveling right now). I don't remember what size it is after the resonator, but I know it's smaller than before the muffler.
