    This product was great for my 2004 Chevy Silverado. I cut off the old muffler and discarded it along with the rest of the tailpipe. I attached this muffler in it's place using a size reducer with a few muffler clamps and it works great. Solid item all around. The muffler puts out a deep, throaty sound at a medium volume when accelerating, but backs off on the volume and droning when cruising at a set speed. My truck "cruises" between 1500-2300 RPMs on city roads and highway, and the drone isn't bad at all. Overall, loud when you want it to be and quiet when you don't. I think it's a great combination. Very happy with it.

    Note: The 2.5" measurement is the INSIDE DIAMETER of both ends. If you use this muffler on an 03-07 silverado like mine, you will need a reducer coupler since the stock piping on the truck is not 2.5".

    I installed this on a 2019 Silverado with a 6.2l. I replaced the Flowmaster FX 71419 due to the interior drone at 75 mph. Exterior noise levels are a tad bit lower than the Flowmaster FX 71419 but a huge difference in the cab. Very little cab noise, a little louder than stock. I did remove both flapper valves. It will get louder as the muffler breaks in as it did with all my other MagnaFlows.

    I just installed this on my 1996 Honda Del Sol which has a full exhaust that originally came with a N1 -Style Canister Muffler. Regardless of having the top on/off, windows up/down, the old muffler was LOUD to say the least. Worst off all, I could not really hold a conversation inside the car and I looked like an idiot taking off from an intersection as everyone thought I was trying to race them! :\

    I am huge fan of magnaflow, but looked at other products first, including the complete Dynomax product line. I wanted something quiet that would not hurt performance (Don't we all). After roughly calculating the required flow my engine would need, I ruled out the Dynomax Super Turbo (regarded as one of the most quiet performance mufflers). The Dynomax VT looked good, but I found many (online) reviews of issues with the diverter valve and spring assembly. The Dynomax Ultra Flo is most like the magnaflow, but costs more.

    This muffler has a high flowing straight-thru design that does not hamper performance. Best of all, the noise level of this muffler on my car is almost stock. It has a really mellow tone that wakes up under hard acceleration.

    I am extremely happy with this muffler as it solved my loud exhaust issue with a quiet, high flowing solution.

    I have to give a good review because of the fantastic quality these mufflers are, but THESE THINGS ARE WAY TOO QUIET!!!! I installed a Magnaflow x pipe and deleted the cats on my '08 crown vic when i installed these mufflers and removed the stock exhaust. I read the reviews thinking they would sound nice and be a good volume, but wouldn't be ridiculous. DON'T BE FOOLED!!! They sound great, they do, but they aren't much louder than my stock exhaust, I'm not sure if its the muffler's fault but I feel like the only reason it is only a little louder is because i removed the cats. So, Im disappointed that I spent so much money on two of these and an x pipe (around 400 dollars) and it sounds no different. I even compared with a decibel reader, and these mufflers are only 3.5 decibels louder, if that. If you want a nice sound, louder than stock, but not obnoxious like cherry bombs, Id recommend Flowmaster 40s. But if you want a good gain in performance but want it quiet (maybe you have a sleeper build in mind) get these mufflers.

    Idk what people were saying how these are "way too loud" like they sound just like stock.......
    Also, I do feel like the flow has been freed up, by a lot. you can look down these mufflers and see through them, they have it flow very well, again, also thinking that they would sound loud, but they dont, but these straight through style mufflers with the x pipe have picked me up like 10-15 hp, with a good brand intake you could see some nice hidden power from your engine without attracting police. So enough of my rambling, still 4 stars because they are good, but I hate that they are so quiet, quite a disappointment.... :(

    Someone at work recommended this muffler after I was looking at all the Dynomax choices and I am so glad I went with this one. If tone is the only thing you are after, then the Dynomax mufflers probably offer a wider range of sound, but if its performance you are after, then simple physics will tell you this is the way to go. If you look into one end of the muffler, you will see daylight out the other end. It is basically a slight S turn in the pipe to give it the offset and its perforated, so this is about as close to a straight through, open pipe design as you will get. The amazing thing is, it still quiets things down. I ran my truck a few days with open pipes (2004 V6 Tacoma) and as long as I did not open up the throttle, I could get away with it. I liked the sound, but there was no way I could leave it that way, and the drone in the cab on the highway was too much. After the muffler was installed, you could tell it was better sounding than stock at idle, and definitely not stock when goosing it to pass someone. Sometimes when I am leaving the parkade at work to go home, I try to stab the throttle real quick to see if I can make it bark and set off some alarms, but it works well enough I can't get it to be that loud.

    I love this muffler and will definitely be getting another one when the time comes for another vehicle.
