I got the Magnaflow #12909 muffler put on my 2013 with the 6.2L engine today. Really not that much difference from the stock muffler, :roll: wondering if I just wasted $175. 
At idle you can hear a tone difference, but that's about it. When you get on it, it sounds good, but not real loud from what I can tell. Time will tell, I'll have to let it break in and see if it changes at all.
This is a pretty quiet muffler so far, so be warned if your looking to replace yours and want something louder.
