Review on 🚗 Dynomax Ultra Flo 17235 Performance Exhaust Muffler by John Contreras

Mounted on Silverado with 5.3l. Everything else is factory except for that muffler. Pleasantly quiet when idling, but sounds more aggressive when accelerating. There doesn't appear to be a drone at 55-60 mph. Updated when I set headers. Edit: Very aggressive with headings. The raw sound of a muscle car. Goes well with a slight cam split. Thumbs up.
