Absolutely not good quality! Broke after 2 weeks

Loved this muffler, welded it on at a local shop, it sounded fine for a week then it got really bad, I thought the muffler was hitting a pipe or something like that, after much inspection I found that it was the muffler itself that cracked the entire top right at the welds! waste of money and time. Definitely not recommended

Pros
  • New
Cons
  • I vaguely remember

Good muffler for performance parts and accessories

I have used these mufflers on other vehicles and have always been satisfied. Installed on GMC Envoy Denali. I wanted more growl in the truck without too much rumble. I tuned in for a little moment as a welder and left the factory resonator. Been using it for a month or so and it sounds good. Windows open, it's not loud and doesn't hum. Windows down, you can really hear it. In general, the sound is very satisfied.

Pros
  • Great price
Cons
  • unreliable

It has a great sound

It has a great sound, not very low but you don't sound like you're in a drag race, just a nice low rumble. I bought my Durango and it had glass bags on it and @ 63 years old I don't want to go back to high school but I still have some of that kid in me and that muffle works great. They won't draw attention like Glass Packs, but you'll still feel the power of your setup.

Pros
  • Best
Cons
  • Crumpled packaging

I did not receive what is advertised, I received a muffler but not the straight pipe muffler as in the picture , which I need, so I do. No modifications are required, one outlet is in the middle and one on the side so it doesn't match the exhaust, and the muffler I have says there's a total other low end brand is, definitely not a dyno WTF, I thought it only happened on eBay, I think it still happens on Revain.

Pros
  • This is amazing
Cons
  • Negative impression

Good sound. Good performance. Good value for money.

I replaced a Chinese fake Flowmaster 40 series on my 2020 Ram with this Dynomax Ultra Flo. I'm much happier with the sound and performance. The Chloemaster was too loud. With its through-hole design, the Dynomax still gave a performance boost, but the extra glass in the muffler reduced the ride significantly. It still sounds great, with a nice quiet rumble at idle and at lower revs, without knocking you out of the cab on the freeway. It's not the perfect silencer, but it's great value for…

Pros
  • Few competitors
Cons
  • 0

Less is more, Dynomax 17220 Ultra-Flo welded muffler.

After removing the bulky OEM beast from my RAM 1500, I replaced it with one of these. The original muffler was rusted through and had several holes, so it was quite noisy. I put it on and what's the difference. My friend said she didn't notice when I pulled up and the neighbors smiled as I drove by. It still has a nice throaty sound but is a lot less loud. People at the driveway windows can even hear what I'm saying without asking me to repeat it a few times or telling me to turn that thing off

Pros
  • Great Design
Cons
  • Volume
