Review on 🚗 Dynomax Ultra Flo 17220 Performance Exhaust Muffler by Charles You

I have used these mufflers on other vehicles and have always been satisfied. Installed on GMC Envoy Denali. I wanted more growl in the truck without too much rumble. I tuned in for a little moment as a welder and left the factory resonator. Been using it for a month or so and it sounds good. Windows open, it's not loud and doesn't hum. Windows down, you can really hear it. In general, the sound is very satisfied.
