2009DodgeRam 1500 Mufflex 14" Magnaflow dual exhaust
Installed the Mufflex retrofit 14 inch Magnaflow muffler. It brought out all 390 ponies in the 5.7 liter Hemi. The old stock muffler was big enough to float down the river on!. If you have a truck that has factory dual Exhaust you want to be able to hear it!!. The Mufflex Magnaflow system achieves just that.I recommend it to all 2009 ram owners
2010 Dodge Ram 5.7 Hemi - Stock Muffler vs Magnaflow 18" Comparison
Just a comparison video on all the scenarios I wanted to see when I was researching mufflers. I hope this will help people who are in need of help like I was. The stock muffler was cut out and a Magnaflow 18" was stuck in its place. Single exhuast with factory resonator still in place. To be honest, I wish the muffler was louder. At Idle, you can barely hear it, and at WOT it sounds a lot like the stock muffler. I think only the city driving sound has improved, as it sounds really nice taking off from a stop at about 1/4-1/2 throttle. One thing to not overlook is that it DOES drone. The reason I went with Magnaflow after all was because everyone said it does not drone. I would've gone with the Flowmaster if I had known this... But I am very happy with it overall. I'll give it a few months to see how much louder it gets, and see if there is any better performance or MPGs from the swap. So far, I can't tell. Here is a link to the exact muffler I bought: http://www.summitracing.com/parts/MPE-11249/
