Yes, indeed they do! My Magnaflows are 20 years old now and I can testify that they do get louder over time. Around town its no big deal but out on the highway it gets pretty loud inside the car. I can still enjoy the sound system but I do have to turn it up! My car is a 1969 Plymouth road runner, 383 4-speed with upgraded cam, rockers, ported heads and Comp XE275-HL10 cam with tti 1-7/8" headers and tti 3" exhaust system with Magnaflow 3" stainless steel mufflers. I have been toying with replacing the mufflers with something quieter but have not yet found a solution.
MagnaFlow all day. Just put one on my 2019 Silverado a month ago. Couldn’t be happier with the sound. Not obnoxiously loud, almost silent at idle/cruise speeds. Super mellow tone under normal acceleration, and sounds solid under pedal to the floor acceleration. Perfect for me
Thanks for giving info about the muffler and how it sounds. I have a cammed 5.3 with long tubes and cat delete and a flowmaster 44 dual out the back but want to do single 3" behind rear wheel.
I have a flow master original 40 single in 2 out. People that I’ve raced says it sounds good but I’m not really diggin it. I can’t decide magnaflow carven or others.
@@slowgoat6089 it will sound most like the loudest version you have. Almost full volume. I had one get knocked off and it basically sounded like straight pipe even though I still had one Flowmaster on Try it, you might like it
Is louder but still good, on my Yukon Denali I install it 3 years ago and sounds better now, but still quiet on highway. Yours still sounds really good
It’s like a whole different exhaust system, I’m about to install a dual in Dual out MagnaFlow and I wasn’t 100% convinced yet, but now I’m doing it lol!
Just installed a Magnaflow exhaust on my Accord yesterday & it seems loud enough for me.. I don't get how everyone says it's quiet at first. I don't need it any louder lol
I got the 4”x9”x14” one. It’s really quiet at first with a stock 5.3. Might update this later but I’m loving the way it sounds. It builds revs quicker and the engine sounds like it had a huge sigh of relief compared to the stock muffler
Use a borla pro xs. Resonator delete aswell on my turbo wagon. 8 months later I now get pops and crackles with a higher note . They do get louder and are best when broken in
well did you ever put this muffler on? I ordered a 12249 for my 05 Tahoe after seeing this video. Hope to have it here and installed next week. No cats, y pipe , maganaflow with single stock tailpipe.
Sounds really good! I’ve had a Carven for about a year now but I recently added headers, deleted the cats and added an x-pipe and I’m not really digging the way the exhaust sounds now. Looking for something new and this definitely caught my attention lol
How is it sounding now about half a year in? I just bought a magnaflow 2 weeks ago. It starting to sound a little louder, I’m recording sound updates 😊
Interesting. I did a single magnaflow and left resonator on. Tried just the resonator with no muffler and it was a little bit farty sounding like a cherry bomb and droned even with v4 disabled. Also didn’t feel as torquey (although butt dynos aren’t accurate). Might give it a few more months to see how it changes.
Is it my imagination, or is the magnaflow louder than the flowmaster was? Now. Because it was quieter b4. And it's got a way better sound than the fm in my opinion.

How long will it take for the magnaflow to get louder. I just installed it almost 2 weeks ago and I already hear a slight difference. Do they really get that loud if you don’t have a cam?Anything you can do to speed up the process? Great exhaust set up by the way.
I’ve had my magnaflow on for a little over a month depending on what type you have it will get slightly louder the packing will settle mines gotten louder
@@TheUndertoe Very interesting. I know there are 2 types. One with acoustic packing and one with fiberglass packing. The one in this video is the one with acoustic packing so either type you have will get louder. It would be interesting if every magnaflow gets this loud 😂
@@smooth235 mines straight through and has stainless packing it was fairly loud first startup anyway they are good mufflers delete the cats and they sound even better mines got no cats
Do you get drone in the cab? I have a 07 classic with the 5.3 and a 212/218 cam and just did long tube headers cat delete on it and have flowmaster 44 on it and now wanting to do magnaflow. Truck sounds great! What magnaflow muffler is that one?
Damn Michael, you actually listened to my videos lol. I saw you commented on a few others. You won’t believe how many people ask what type of muffler I have or what I have done to the truck when I state it in the video lol. I appreciate it.
Oh shit now I know why it sounds so familiar after a years worth of miles on the magna's they now sound identical to brand new loud mouth 2 mufflers check them out and loud mouth 2s keep that sound years on end!!!
I had a pair of Magnaflow Magnapacks on my 2001 Mountaineer 5.0 and just couldn't deal with the that underwater raspy fart clapping type growl they have so I switched them out for a pair of SLP Loudmouth 2s.
@@chrisgarcia7883 sorry I wasn't more specific on my setup, factory cams, stock GT40P heads, Torque Monster shorty headers, true dual 2 1/2 inch pipes going into a 21 inch X-pipe from summit racing, Flowmaster 200 cell cats, and a pair of SLP Loudmouth 2 mufflers. Also Borla S-Types are very similar sounding to Magnaflow Magnapacks but the Magnapacks are in between the S-Types and ATAKs in loud decibels.
So you bought this Muffler stand alone right? Did you just buy and install your 3" Pipe from your Y-Pipe to the muffler yourself? Im looking at doing it this way rather than buying a complete cat back system kit from Magnaflow. You have it dumped right before rear wheel right?
Which Magnaflow muffler did you put on your Truck. Is it a full dual exhaust. 2 mufflers or a single muffler dual pipes. I've got a Ford 468 that's built up and was curious if 2 mufflers would be better than the factory 2 into 1 exit.
can't believe - I have a MagnaFlow installed on my XJ 4.0 for a couple of years now and there's nothing comparable to the sound of the MF on your truck over time - mine sounds nearly the same as in the beginning - don't know what happened to your truck - however I'd appreciate your sound !
I just put Magnas on my tundra and I'm like these are to quiet, looking forward to mine sounding like your one year video, How long would you say the actual break in was?
@@gasparandres1990 I still have mine, they are still quieter than I expected. Only time I hear them is when first starting up the truck and heavy acceleration.

No way that Cam is stock. What else has been done?Forgive me if you have answered this in prior videos. This is the first of your videos I’ve seen. Sounds like a BTR stage 2 cam or something comparable. Either way it sounds good.
I have a Cammed 6.0 Silverado 2500 with a magnaflow. I’ve only had it on a month. It’s actually very loud and the drone is so horrible I don’t want to hardly drive it. lol just wondering if you had drone or if you did anything to fix it? Thanks
I love the sound of MagnaFlow but hate the fact that they get louder in time. Been looking at the 18” (part number 12288) for my Ram but I don’t like the sound of the year later section on here at all. Extremely too loud and aggressive for me. I don’t want my Laramie sounding like a hot rod.
Magnaflow Muffler: amzn.to/2qy2BVd
Is that the one you have?
@@Sam-vs8dt it sounds cammed he definitely did some work to that truck
100 percent cammed
Get a magnaflow part number 12579 if you think it’s too loud. I have this on my 6.0l vortex motor. 1 7/8 headers Catless to that muffler

Sounds great to me one year later! 🤪
How many miles did you put on until it got this loud? Or did it take about a year to get louder? Sounds awesome
And you added a cam😮
Too loud? Maybe for your neighborhood but sounds great to me.

Big difference. I prefer the muffled quieter sound. What are the dimensions on that muffler you used?
Dang thats a ton louder! Jeesh
Thank you ... well done. Video says it all. Sounds great.
That thing rolls out I'm gonna have to see what all you did other then the obvious exhaust and cam
Great looking and sounding truck
Use a borla pro xs. Resonator delete aswell on my turbo wagon. 8 months later I now get pops and crackles with a higher note . They do get louder and are best when broken in
