Good mufflers.
AI summarized what I said so here it is. Overall Experience Effective at reducing exhaust noise when used in a well-designed system Not sufficient as standalone noise reducers for very loud setups Installation & Fit Weld easily into place Fit well within tight space constraints Maintained solid structure and clean appearance Performance Reduced noise, but not dramatically on their own Eliminated drone when properly integrated Best results achieved with additional components: H-pipe before the mufflers X-pipe after the mufflers Design Insights Proper exhaust design is critical for optimal results Multiple redesigns may be needed to achieve desired sound Combination of components significantly improves performance Build Quality Durable and solid construction Maintains overall exhaust system integrity Key Takeaway Good quality mufflers that perform well as part of a thoughtfully designed exhaust system, but not a complete solution for noise reduction on their own

Sounds good, minimal drone
Little quieter than like a 40 series, less drone inside the cab but sounds about the same at Idle.. Revs are raspier than a traditional flowmaster. Overall I’m happy, wish it was slightly quieter maybe the bigger square one is quieter? I tried to see if there’s a difference in sound between the two but couldn’t find anything, but it’s an upgrade from my straight pipe old exhaust..

Great value
Was looking for a glasspack muffler. This Flowmaster was the same price and in some cases cheaper than so no name brand. Easy install, sounds awesome at idle and sounds great going through the RPM range, once you get to redline, it doesn't sound as good, but it's livable. There is some drone at highway speeds, but not annoying, it's better to hear the exhaust than not. We'll see how long it lasts and I had read other reviews that say MagnaFlow or Dynomax were better, but cost a lot more. This is my "go to the junkyard" truck, so it doesn't get driven as much as my other vehicles, so I believe this should last the life of the truck or even longer. Oh and it looks good.

Put on my 07 ram (has cats, no resonators) and it sounds very very good . Minimal drone at cruise or at highway speeds but just a touch loud for my liking . I have used many different brands of mufflers, but this one put on a Hemi almost gives it a slight lope/chop at idle or cold start that is pretty impressive . Would recommend if you don't mind it being on the louder side, but what do you expect for a straight through muffler. definitely not as loud as a glass pack.

utilice este silenciador en cada línea de escape (2) previo a unos súper 44, que daban un tono muy agresivo y resultó un tono muy agradable en bajas revoluciones y a la vez muy bien marcado cuando se acelera. muy satisfecho bien recomendado
