Need some help in choosing between the Flowmaster series supper 44 and the 50 series HD. Which out of the two sounds the best but not to much drone in the cab? And which one performs better on 5.7 Hemi. I have a 2009 Dodge Ram 1500 Sport. Thank you for your help!

 

when I was looking for a muffler i was looking for the same thing. What I read was that the 50 series HD is the way to go as far as less noise in the cab. Good uck with your search

 

I agree. I went with the 40 series on my 09 Ram Sport and I love it. It does have a little drone at highway speeds. I heard the 50 hd has very little drone if any at all.

 

40's here too, little drone but........ it sounds nice LOL
