Review on 💨 Dynomax Ultra Flo 17223 Exhaust Muffler: Supercharge Your Vehicle's Performance by Harry Ashcraft

Silencer as advertised. It installed on my 2005 Sierra 1500 in about 30 minutes at a local muffler shop for $50. I used to always have a Flowmaster, but I wanted something more subtle. It's much quieter on takeoff and smoother around town. The flow is better because of the one-through design. Very little cabin noise which was one of the goals with this purchase. Finally, when you step on it, it roars, just the way I like it. This is a great option for those whose wife is annoyed by the constant noise of the Super 44 exhaust but still wants more power and that exhaust sound.
