Review on 💨 Dynomax Ultra Flo 17553 Exhaust Muffler: Silencing Your Ride with Optimal Performance by Todd Foster

This muffler is amazing. I chose to weld mine as I am a welder. I chose 2 1/2" ID to match my 2 3/4" OD exhaust. I have a large 6.0 liter small block 364ci engine in my '99 Chevy Silverado 2500hd. My stock exhaust just didn't suit me and started to fail. I wanted to release this beast. I added a cold air intake but it wasn't enough for what I was looking for in a truck. After the installation I started it. Wow. What an instant difference in sound. Deep hum. Sounds great at idle. This truck sounds like it has a big block under the hood. It rumbles a little at cruising speed, but that's to be expected from a more powerful exhaust. In terms of performance, my engine can now breathe a sigh of relief. No lag when accelerating. Good performance. I would definitely recommend this muffler to anyone looking for a change in sound and performance. This silencer also has an integrated X-pipe. You get all the power in one muffler and don't take up much space.
