Review on 🔊 Flowmaster 3.00 Offset IN/OUT 943053 Delta Flow Muffler - Moderate Sound, Black by Pushkraj Barton

I installed this to replace the 40 series that was on my Chrysler Aspen '07 with a Hemi. My MDS is disabled so I can't tell you how it will sound, but so far I'm loving the 50 series. It is significantly quieter than the 40 series, but with the same performance. I get 1mpg better than stock. When you step on the gas, it sounds really good, but not nasty. At a speed of 70-80 km/h it is quite quiet. I notice a hum at 30-40 km/h at low revs. My resonator doesn't work. Again, I'm not running MDS.
