Review on MagnaFlow Exhaust Products 12278 Muffler by Jake Larson

I bought this for my truck (09 Dodge Hemi) and it has the right sound - Hemi opens and sounds means under WOT but in daily driving I can still talk to my kids and wife. It does the job. One thing to note though, despite a lot of research online stating that an 18" muffler doesn't hum, I've concluded that it does hum and that's a problem. However, after a week the drone became quieter, despite my expectation that it would become too loud. Don't get me wrong - it's still there, but not as bad as day one. I also tow a 5500 caravan and the noise level was acceptable to my liking.
