DynoMax mufflers
Anyone ever use a DynoMax muffler??
This is the muffler I saw on a 94 C4 and it sounded awesome.. Just curious if anyone has any good/bad experiances with them.

I think they are a great muffler over stock. The only problem, that most people who have them can agree on, is the brackets fall off easily. If you get a set, I would advise you have them welded for extra reinforcement.

I have these on my C4. They are straight through and work pretty well.

So in essence isn't this a jumbo glasspack? What do these suckers cost? I started a thread in tech about CherryBombers, most people seem to think they sound like crap or that magically they flow less then stock mufflers

I have a set of the ultraflows (stainless) on a 2 1/2 inch exhaust. I like the sound. I am not a big fan of the flowmaster sound so these mufflers suit me. They have been on the car for 6 or 7 years and are holding up very well. Bradvette heard them in full song at Carlisle when we reved it up for Chip Miller. He liked it as well.

I wish someone like Magnaflow or Flowmaster would make mufflers with the LT1 square tips. Unless I'm looking in the wrong places, the only ones I have found are the Borlas, which are a little pricey in comparison with the aforementioned two.
Only drawback to the Flowmasters is every Mustang in town has them.

I had a set on my old Nova for a while and it went mid-11s at the time. Was actually quicker with the mufflers than with open headers.

Corvette central sells a magnaflow muffler with lt1 tips on them. They are aluminized and not stainless, but they do have those tips.
P.s. i have the super turbo mufflers on my car now and they sound like crap, Just a heads up...

If you get the cherry's let me know what they sound like..
Actually PepBoys and Kragen sell them for 19.99 ea. (used to be 14.99 a year ago!) in all diameters and lengths - so not sure if your $30-70 included both or what...

I have the Dynomax on my 85-they have the duel outlet--they create quite a resonance in side from about 1400-1900 or so--sound great outside but the resonance is a pain--I ended up putting in removable plugs of different diameters to help with resonance--which seemed to help-I pop out the plugs when I autoX --but for daily driving the plugs go in to help reduce the "Buzz" inside--

Here is both dynomax mufflers (88 vette) cut open.
Did my best to highlight the insides and flow path.
The Super Turbo
Only real flow from one tailpipe, the other only let out noise.
I wound up plugging the "noise" one, and sound was little louder than stock.
Notice the fiberglass packing is almost gone, mufflers only a year old?
The Ultra Flow
Straight thru, much better packing glass than turbo.
Dumps into a chamber with both tailpipes about equal flow.
Very good but very LOUD sound.
I'm a magnaflow convert also, running them now.

Thanks for the heads up, would have never known. Magnaflows are great mufflers, my local muffler shop is a dealer. They may be able to get them.
Does anyone remember "Purple Hornies" by Cylcone Headers? These had a great sound. They were out in the early '70's.

Mine sucked... Both mufflers rust from the inside out and broke right at the rear hanger within 3 years...
Poor customer service, poor quality product, etc... NEVER AGAIN...
I posted my expereince with them in the reviews section of the forum if you want to read the whole deal...
I'm running a Flowmaster Force II system now and couldn't be happier...

I've run the Ultraflo stainless steel for 4 years, the still look like new, have a great sound too! I do have to agree that they create a lot of resonance but I usually have a window open and the stereo on very loud!! When I stand on it they really talk!!
