Do Magnaflows Get Louder Over Time? (1 Year Later)

I think the Magnaflow exhaust sounds even better now! But unfortunately my initial intent was to make the truck quieter..

Wow, the muffler is much louder after a year. It definitely sounds better now, it had too much of the muffled fiberglass sound.

It just hit me that that's the best sounding 5.3 LS I've heard so far

[justinsilicato]

I love the 1 year later sound that's exactly what I'm looking for. Thanks for the video.

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

When do they start selling the “Year old” version? Life long Flowmaster guy, immediately jumps on the MAGNAFLOW train.

Sounds badass. It's got an edge to it now.

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.

Thanks for the up my mind, going with the Magnaflow!!!!

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

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!

[rubensalais]

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

[roadstomadness]

How many miles did you put on until it got this loud? Or did it take about a year to get louder? Sounds awesome

[dougcoleburn]

Which mufflers did you use. Part number? Thanks

[costigantx]

Too loud? Maybe for your neighborhood but sounds great to me.

[irwinjimenez]

Big difference. I prefer the muffled quieter sound. What are the dimensions on that muffler you used?

[tonksT]

Just had a magnaflow put on my Tacoma the thing is so quite!! Like so quite really hope it gets loud

[justus]

I’m sold Magna Flow it is!! Awesome Vid!!

[RC-zmir]

Would you please share you exhaust setup from manifolds back OMG best sounding 5.3 I have ever heard my tahoe needs that in its life!

[bobbyfinley]

That thing rolls out I'm gonna have to see what all you did other then the obvious exhaust and cam

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
