It's nice. I like the sound but I do wish it was a little louder

Not Quite What I Expected but Still Like It.

Reviewed By Dan S (Coldwater, OH) Reviewed for a 2009 Dodge Ram —8/12/2016 1:52 PM

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.

Loud and proud

Reviewed By Cody M (FAIRHOPE, AL) Reviewed for a 2005 Chevy Silverado —7/25/2016 9:47 PM

Not quite as powerful as straights, but way ahead of the other flowmaster models. I have the 3" in and dual 2.5" out and the sound is awesome. I have 12" turndowns right where the bed meets the cab so that causes plenty of cabin drone. Overall great sound from outside. Going from stock to this even added enough hp that i can spin my 35x12.50s on dry pavement. Something i couldnt do before!
