Yes sir! Grandpa sir!

 

You need to quit comparing me to your poor old daddy. He is younger than me but seems older, he had the responsibility of raising you! That would age anyone before their time.

 

**Stealth thinks.........Must respect the elders**

I think you two are different breeds.

 

Yep, you are probably correct. He stayed with the challange, I would have sent you back after about 2 days.

 

Now that hits home. I was the first born son.

 

If you sort through all the chit people post, you still haven't seen one of them post a dyno chart, a graph, or even a shoddily put together spread sheet or link to prove their points. That because they don't have them. The best that can be thrown out here is that "my buddy said that his friends tuner thought that brand x beat brand y because....." The one and only arguement even worth debating here is the stainless one, and Flowmaster offers stainless mufflers. Those of us who've been running them for years without even the slightest inclination of rust know we don't need stainless and don't waste our money putting shiney metal on the underside of the truck. All you get with a crap can is that, a crappy sounding can. Cut your precious magnafart in half and what do you have beyond an oversize slightly quieter glass pack? Nothing, the guts are the same.

Flowmaster, origonated in 1983 as a solution for Sprint Car Racers

MagnaFlow got its start as a natural extension of Car Sound Exhaust Systems, Inc., that specializes in superior catalytic converter technology.
The date that magnaflow began, is amazingly enough (sarcasm) not listed on either of the websites they are attached to.

Now, lets compare a little of their R&D to see who does more in development.

Car Sound (this would be magnaflow) conducts business on six continents and produces and distributes product from three facilities in California and one location in Italy. The California facilities are made up from a 50,000 sq. ft. Company Headquarters, a 30,000 sq. ft. R&D Tech Center, and a 150,000 sq. ft. Manufacturing Center. In 2006 Car Sound will open a new 250,000 sq. ft. Distribution Center in California. The Italian facility is the company’s European Sales & Distribution Center.

Today, Flowmaster, Inc. is housed in two ultra-modern facilities together totaling over 400,000 sq. ft., one in Santa Rosa, and the other in West Sacramento, California. Flowmaster operates the only exhaust Research & Design facilities of its kind in the world, centered around the SuperFlow SF-7100 engine dynamometer complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dyno's. Through use of these dyno's, Flowmasters engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers "to the ground." Flowmaster also utilizes Spectrum Analyzers to fine "tune" the sound of each of the eleven different series of mufflers that Flowmaster currently offers, both for peak performance and just the right sound levels and tones.

Back to the bottom line.......Flowmaster does mufflers. Magnaflow is a division of a company that quote "makes thousands of products...." Flowmaster was derived from a racetrack need, magnaflow was a byproduct of emissions related components.

Shall we continue?

 

We can continue if you would like but it will never end
As far as price i paid $100 for 2 14in maggies shipped,prob cheaper than flows and they are stainless
As far as sound my maggies are alot louder than the flowmaster 40's were.
Also i get more comments on the maggies sound than i ever did with flows so i dunno man

 

Wow, I'm impressed!!!

 

dynomax bullet.. Sound.. Performance... $39 bucks shipped from summit... Will never own another muffler besides a bullet... I bet it would even tickle old man Stealth's fancy.. Not too loud, not to quiet and it performs.

 

98Navi, you've either got to be a used car salesman or a Flowmaster dealer. You're so full of bs your eyes are probably brown.

Here's the pertinent Magnaflow info in case anyone is interested in anything more than the one paragraph he snipped that has nothing to do with with R&D (they call that spin and deflection). Since when does square footage of floor space = a better or more knowledgeable company? (BTW, looks like the Magnaflow R&D dept. is 30k square feet all by itself.. Flowmaster's may consist solely of a broom closet in their dubious 400k total sqare feet )

I'm still waiting on your dyno pulls to prove all of these guys wrong.

 

Click this link. http://www.magnaflow.com/01home.asp
At the bottom of the page on the left side it says "see our syno sheets".

Can't get much simpler than this.

I already stated in a previous post that Magnaflow puts this on their site. Yes it's their own site, I know this, but I didn't see any dyno charts on Flowmaster's website.

 

Im not trying to say that the mags don't improve power, Im sure they do. They aren't however supperior to the flows. I will not own anything but Flowmaster just on the sound, I love the Flowmaster sound. I know they improve power though and so do Magnaflows. You guys try and make it sound like your stainless muffler is made of gold. You only need stainless maybe if you live in a place that has the roads heavly salted, and flowmaster has stainless to. So lets keep it to design.

Right from Flowmaster

"Flowmaster vs. "straight-through" muffler designs

First you need to understand the technology of a "straight-through" muffler design. "Straight-through" muffler designs utilize a packing material wrapped around a piece of perforated tubing to absorb sound as its traveling through the muffler. This internal tubing is generally reduced as it enters the inlet of the muffler to help achieve a further reduction of sound as its exiting the muffler, smaller hole, less sound. At the same time this creates a further restriction for hot exhaust gases traveling through the mufflers.

Why should I buy a Flowmaster?

Since Flowmaster mufflers use sound energy cancellation technology, you don't have to worry about "packing material" deteriorating and getting louder after as little as a few months.
The interior case volume of the inside of a Flowmaster muffler is far superior to that of a "straight-pipe" or "straight-through" muffler design. Imagine filling a "straight-pipe" or "straight-through" muffler with water vs. filling a Flowmaster muffler with water. Which one do think would hold substantially more volume?
The deflector in a Flowmaster muffler acts as a one way check valve eliminating reversion back to the engine and creates a low pressure area to help scavenge the exhaust.
Flowmasters use fully welded construction for added strength and durability to last even when installed on high horsepower engines.
Flowmaster mufflers are made in the U.S.A. "

 

If you look at the gragh for a 5.4 F150 wheel dyno, it shows that at peak torque there is only an improvement of maybe 5ft.lbs. There isn't any real difference until about 3800rpm. That is also around the weakest point of the torque curve. How many of you really go up to 4000rpm? So according to the gragh there isn't any improvement at the normal rpm's used in daily drive/towing. Thats proof (on their own site) that the mags don't improve low end torque, or this sudden better throttle response that you claim. There isn't a difference until higher rpm's.

 

I dunno about a catback system,never had one so i can't say.

I know someone on here had to dyno?
I myself love the sound of flows also but they did not perform well for me in my situation.I know Troyer must have some numbers.

 

I read about 50 threads similar to this one. And I am still unsure which way to go. I joined this forum for all the advice and knowledge and wound up liking what I have seen so much that I decided to do some stuff to my truck.

I have a 6" lift and Procomp 35's going on my 97 flareside this weekend. I am beyond psyched to see the finished product. On my way home I plan to drive in and get an alignment and across the street is an exhaust shop.

If the truck looks mean, it would be great to have it sound mean as well. BUT- its only got a 4.6. For this reason I thought the flowmaster would let people know its an 8 under the hood. If I spend the money on Magnaflows instead- can I get a loud Mustang type of sound out of them?

I havent heard anyone with a 4.6 and either type of exhaust to do a real life comparison
