Magnaflow Performance Muffler SOUND?
I recently had a Magnaflow Performance Muffler #12266 installed (a Midas friend Manager did a PERFECT WELD) and was a little disappointed in the actual sound. At idle, it sounded almost stock and it really is hard to tell at highway speeds. Now I was looking at sound clips and one company stated it needs about 400 miles on it before it "settles" in. Anybody find that when they installed their muffler, it actually did improve the deeper growl overall as it broke in? Thanks

Longtubes will make it louder
|
It will get louder with miles. Not crazy loud but louder.
|
Mine sounded great with long tubes and no cats. Even better cutout open :twisted:

I had one with no other mods wayyyyy back when. It will get louder but don't expect it to sound like a racecar.

Typically Magnaflow has a little more rumble than stock at idle and can be a good amount louder (with a nice tone) when part throttle or above - have a MF catback on my L98 GTA - I like it, not too obnoxious.
Each brand of muffler has a distinctive sound - Corsa for example can be loud as F and is very agressive sounding, MBRP can sound similar to Magnaflow, but is going to be louder. |

I ran a used magnaflow for several years on the stock exhaust and always felt it was too quiet (pretty much a deep bass note), never got louder over time. So I put a cutout on. But cutout with stock manifolds/ypipe sounds like trash, so I did LTs and catted y. Sounded better but still not loud enough. So I swapped to a hooker aerochamber. Then switched to ORY and ditched the cutout since it always leaks. Now I have an unbranded muffler that essentially doesn't muffle anything, and I think I'm happy with it... for now haha

i had a magnaflow on my car before. i also have 1 7/8 LTs and it was still wayyy to quiet for me so i switched to corsa.
|
I have gmmg... Sounded way better after changing out my ****** flowmaster. Now it's way too loud with LTs and no cats. Raspy around 3k. Lol
|
when i had a flowmaster exhaust put on my ram i was very disappointed with the sound and it sounded a little louder than stock. after a few hundred miles or so it really woke up and was the sound i wanted. he's right it does take a few hundred miles to wake up.

see the photo here: https://www.autohance.com/borla-1488...vrxGgJcOvD_BwE that is a totally different setup than a magnaflow exhaust setup or any other cat-back exhaust kit for these cars I bought a magnaflow cat back kit for my 2006 dodge ram 1500 from CTW MOTORSPORTS and installed it right there at Paul Huryk's shop in a few quick hours. it was indeed louder than stock exhaust. It was definitely a different quieter sound for the first 300 or so miles and then it opened up. I love the way it sounds now after about 2 years of being in use. It sounds perfect for this truck... which is not an fbody, but I am just giving you another magnaflow related example. |
In my opinion, Magnaflow is on the more mild side of aftermarket mufflers (especially for f-bodies).
However, every aftermarket muffler I've experienced opens up after a little bit. |
on the 4th gen borla, I thought the bypass plate made it so its a true straight pipe? That's why its so loud lol. my father has it on his 93 and its loud
|
You can get a SOLID plate from BORLA and cut out the center section with about the size of half dollar. I used this to get a really nice deep tone on the Formula.
Has anybody ever noticed that there must be about 15 muffler companies that make a system for the 5.0 Mustang and everyone sounds throaty. Some even sound better than a NASCAR. I don't know why, but maybe it's because of the horizontal design that is unique to this system. |
Stangs usually come factory with some form of H pipe, unlike the crappy Y into a Y fbod rasp design
|
Mustangs sound the way they do because of the dual pipes and h-pipe equalizer. Not much different than a 1st or 2nd gen f-body with a similar style exhaust.

I called Magnaflow today and asked about the "break in "period. Yes, it will get some deeper volume in time. The muffler that was made for these models, was meant to be an OEM REPLACEMENT, so sound was not a priority. He suggested to wind it out at highway speeds and move the packing around for the next 400 or so miles. I was disappointed that a company that does advertising for performance cars would sell something that you can get from a Midas shop. :|

Wife has a corsa on her 16 5.0. Sounds really good. I've never heard of a muffler break in period or one getting louder? Interesting

The Y with my LPP headers is super ******. I think this merge might help the rasp a bit... I have never heard of a break in period either on mufflers |

I had a magna flow with me the entire time, I loved how it sounded, from factory to cammed.
|
In Russia, muffler gets quieter over time!
