Review on Dynomax Ultra Flo 17233 Exhaust 🔥 Muffler: Superior Performance for Optimal Exhaust Flow by Steven Chiumento

Very good cold start sound. It has the kick I was looking for back then. But when driving it is almost inaudible. If you give it a few revs and you're behind it, that doesn't sound bad either. I hope it gets a little louder over time. I had a Flowmaster 40 on my old truck (Silverado 2011) but didn't want my new 2019 Silverado to be that loud. So it depends on what exactly you are looking for. If you are looking for a loud and aggressive sound, this muffler is not for you. If you're looking for some hum, this is it.
