Exhaust Silencer Review
I recently installed this exhaust silencer on my vehicle, and I’m really impressed with the difference it has made! The noise reduction is significant without sacrificing performance. My car now runs much quieter, especially at higher speeds, and I no longer have to worry about disturbing the neighbors or attracting unwanted attention. Installation was straightforward, and it fit perfectly on my exhaust system. The quality of the material feels durable, and it’s clear that it’s built to last. I also appreciate how it didn’t affect my engine's power output—it keeps things quiet while still maintaining the overall driving experience. One of the best features is how it manages to reduce noise without creating any rattles or unwanted vibrations. Plus, it doesn't add any extra weight, which was a concern I had before purchasing. Overall, this exhaust silencer is a great investment for anyone looking to cut down on noise while keeping their vehicle’s performance intact. Highly recommend!

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.

I have it on my 5.3 and it has the perfect sound 110 db on RPM 3 and it increased the MPG when on cruise control

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.

This muffler was a little louder than expected but sounds fantastic...... think old muscle car. Super deep throaty sound but loud. Only issue is resonance. This bad boy resonates like crazy..... so I put a MBRP 3” rolled tip on it and played with the length. Think trombone.... the more I slid the tip out the quieter it got inside the cab. It really focused the sound outside of the vehicle.... like amazingly ! Love the sound ..... just buy a tip to help perfect the sound. Built quality is excellent and stainless to boot.
