Had the #12588 installed with the Y-pipe upgrade on my 2009 Dodge Ram. This is my first Magnaflow muffler, and after watching numerous youtube videos I went with the 22" in fear of the drone. I was expecting to hear more of a difference when accelerating over stock, but I'm still early in the break in process. I've noticed a slight drone around 1500 rpms, it's not bad and could go away over time.
