That's a good question, i don't know which mine are either. All i know is they're pretty mellow at cruising speeds but the harder you accelerate and the more throttle you give it, and the more load that the car is under, the louder they get up to the point of being plenty loud enough.
This is the kit that i have according to the guy i got them from. It still doesn't really say which muffler is in the kit. http://store.summitracing.com/partde...5&autoview=sku

I think there are only 2 series(could be wrong) regular ones that are similar to dynomax ultra flo but with a welded case and Magna Packs which are like glasspacks sort of and are louder
I have a 95 GT and all I have is the regular magnaflos welded in where the oem mufflers where with the stock tail pipes,h pipe etc. My car is really quiet...only slight noise in the 1200~2000rpm range. Slight drone...not like flowmaster....WOT its smooth and louder than stock for sure but doesnt sound like a fat guy farting or like your neighbors 71 f250 with flowmasters.
However I bet the flowmasters would sound alright with a car that still has catalytic converters and stock tail pipes.
I like my magnaflows though..stainless steel and loud enough but quiet enough the stock stereo can be heard at normal levels |

Personally i LOVE how 3 chamber Flowmasters sound, they're just not loud enough for my taste. If i had some kind of V8 family car i'd get those in a heartbeat.
The only reason i have my Magnaflows is because i lucked out and only have $50 in a catback that only has about 3k miles on it. I traded some 2 chambers for the mufflers and then bought the tail pipes for $50. Otherwise, for the money i'd go with Mac or piece together my own kit and get Spintechs. I will say though i'm not in any hurry to swap these out (and that's rare for me..lol). |

Don't get MAC's if you are running an offroad H-pipe, they sound like crap IMHO. I had my MAC's swapped out for some IMCO's and it sounds awesome now. |

Magnaflow makes "MagnaPacks" which are THE LOUD ONES. They are shaped like glasspacks. You will know if you have these, they are f'n loud and sound pretty angry.
They also make standard "Magnaflow" mufflers which are shaped like a conventional muffler. These sound the best imho. |

I'm not sure if there are different grades of magnaflows. My set is the 2.5 dia universal stainless steel muflers, they ran about 70 a piece from my local auto parts.
Magnaflows are great muflers, they flow wonderful and add power and are generally quite at idle but then once you push the rpms up and accelarate then they sound so nice. My 87 hatch is my daily driver since I wanted a mufler that was quite at idle but still sweet sounding under load. |

Its either straight Magnaflow muffler, or Magnapack.

The 'packs are louder, but I can't say I care for them on a 5.0.
As for MAC, they sound AMAZING with an off road X, but like chit with an H. I'd get an X pipe before getting a new cat back.
And the 3-chamber Flowmasters...everyone says they are so quiet. I have had them on 3 different cars and they were all PLENTY loud!! YouTube - 1992 mustang 347 stroker <--- this is not "quiet" maybe a bit at idle but i assure you that in person it has just as much of a deep sound to it as any, and they have a killer scream when you get on it. Short exhaust clip of 2003 Mustang GT. BBK 2-Cat H- Video <---- this is my old 03 GT that had a CATTED H pipe and 3-chambers...not quiet either. People would often ask me if I had cats because the car was loud enough to question it. |

FWIW, I actually like the sound of the 3-chamber Flows on Frankenstang's Capri (behind an off-road X) but I hate the way they fit on there with the flowtubes welded in position and the hangers on the tails being bent/welded all wrong.
Still kinda torn on what I want to use for a cat-back on my '84 whenever I get around to throwing duals on there. At this point I'm leaning towards piecing together my own cat-back by getting the flowtubes and tails separately, and then throwing on whatever muffler of choice I want - leaning towards Magnaflows, although I do really love the Pypes Violators, too.  I LOVE the way Magnaflows sound on my buddy's '04 Mach 1...  |

the second is the magnapack and they are straight through, but the pipes before and after it are slightly angled so that the muffler can be mounted at a slight angle, still achieving an 'offset' design....here is the Magnapack in mustang cat-back form... 
i had magnapacks on my 97 cobra, with stock headers and H pipe...heres an idea of the sound... Crappy exhaust clip of 1997 Mustang Cobra. with on- Video |

Ok....so who's got clips of the Magnapacks? Do they sound any better than Bullets? I had Bullets for about 1/8 mile and couldn't stand'em and took them back off. |

Not unless you get some custom-bent pipes... |

You could if you bought the Magnapacks just by themselves, and then did a REALLY good job fabbing up the flow tubes that go from the mid pipe to the muffler so that they S bend out to towards the frame and put the outlet in the same spot as your typical offset muffler outlet. This way the Magnapacks would be in the right place to put your typical tail pipe kit on without having to do anything custom to them...so you'd just need custom flow tubes, which any muffler shop should be able to pull off with no problem.
In fact it would be awesome if Magnaflow or even Dynomax made something like this for their tube style mufflers. | | Thread Tools | | | | Display Modes | Rate This Thread |  Linear Mode | |
