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 money. I would recommend it.
