Review on 🚗 Dynomax Ultra Flo 17554 Performance Exhaust Muffler by Jason Winkfield

UPDATE: After 1,000 km the sound in the muffler has improved. A fully rounded sound is still missing. But things got better. Overall, my muffler didn't have the build quality issues that other reviewers had. While the muffler is doing its job, it's very quiet in my truck. I have a big 8.1 liter block and the muffler doesn't sound much louder than stock. Conclusion: I would not recommend this muffler to friends and if I had known that the sound was quiet I would not have bought it.
