I installed this on a 2015 Ram 1500 and it sounded amazing. There are videos on YouTube of how this muffler sounds on a 5.7 liter Hemi. I had a straight glazing tube on my 2012 Ram 1500 and I liked the sound it made, but the hum was terrible when turning eco mode on and off. This Super 44 muffler still hums a bit, but not as much as the glass pack. It's a deeper, throatier sound, and when I get it right, it pops a bit. Like the sound.
