I called MF several years ago to ask for flow numbers for a specific muffler and the sales guy said they would NOT provide that information to me. Glad someone was listening. BTW, David Visard says that you need a muffler that flows 2.3 CFM per open pipe HP to have a lossless muffler.
Magic Questtion: How much CFM would be on the display if the pipe and(!) the muffler are mounted on the test bench?! (more like a regular exhaust system) Is it somewhere in the middle?
@@SummitRacing 🙌😉Regarding the comments exhaust systems seem to be a very interesting topic. 🔥 Maybe it's worth to wait for some more and to discuss them with RICH and listen to his expertise. BTW - great contents - thanks for posting. 👍👍
I say this test is not totally accurate because exhaust has pulse waves that slow down and speed up. Exhaust does not run at one consistent and steady full blast speed. If you watch the muffler and how much longer it actually took to get to the strait pipe reading then there you go it is slower. So what does one think will happen with the actual exhaust waves with all different speeds coming from the headers going faster and slower and the slower ones having to catch up but then they get canceled out by one or 2 more waves? I like MagnaFlow but nice try on selling them lol
Thanks for watching and commenting. You are right about the waves/pulses, and he does cover that at the 5:30 mark. But at full capacity, the muffler is able to keep up with and exceed the flow of the straight-through because of the perf-core inner design.
@@SummitRacing im not gonna lie, I stopped watching after the Magnaflow was tested after the strait pipe in the beginning. Once I saw how fast the open pipe hit peek flow and how the muffler struggled and then finally caught up and went a little past it I was done. I also noticed the Magnaflow fit much tighter on the flow pipe than the strait pipe 👀 I use to be a Flowmaster guy back in the day but grew out of them. I like Magnaf;ow and Spintech but I have been running 3" open pipes for years. Infact I just made new ones 2 months ago.
That muffler that flipped over that pipe is the same size all the way through so it's actually a little bit bigger than 3 inch all the way through I believe isn't it?
I don’t comment much but I feel dumber after watching this Hey magnaflow that goes on the back of the car not the front you don’t pull air through the muffler it’s not an air filter Pulling air through something is not the same as pushing air through something Pushing expands air and makes it tumble on it self and slow down pulling air makes it want to follow a straight path and not tumble on its self That muffler acts like a sorta Venturi speeding air up when it’s pulled through it compared to the straight pipe That muffler test makes no since Blow air through both and bet the straight pipe wines There’s not one dyno muffler challenge on you tube where substituting a muffler for straight pipe made more power Snake oil and lies Straight bs
But how much flow does your engine produce in a single pipe? For instance, a Suburban can hold more than a Civic, but if it's just you and your wife, the extra space is wasted.
This is null…. First of all you’re flowing COLD air through that muffler …. Secondly when those mufflers break in and those fibers melt …. That muffler will eventually turn into a straight pipe
Would love to see how the different styles of mufflers flow. Flowmaster vs borla vs corsa vs magnaflow
Most brands have pretty similar designs (aside from spintech)
You'd be better looking at a 40 series versus a flowfx versus an outlaw
Excellent Information!

Good follow up question. We can certainly ask Rich and the gang at MagnaFlow.

Any drone? So almost like black widow mufflers?
How about single pipe split into 2 pipes & mufflers vs single pipe single muffler?
I would love to see some spintech mufflers on there
Are spintech raspy mufflers?
@daviddup1978 at idle I think they are very deep. At high rpm they get a little raspy but less than flow master in my opinion
I would have never guessed that muffler weighs 14 lbs! 😮 28 lbs in mufflers? I'm guessing the stainless steel is part of the reason but wow!
How about a muffler that has an offtet inlet and outlet and use a curved pipe to compare
If you want to try and be more quieter, why not put two in tandem ?
An additional 14# against lower sound but Higher FLOW....
Simple theory… the “perforated” tube breaks up the surface stiction of the air…
I don’t comment much but I feel dumber after watching this
Hey magnaflow that goes on the back of the car not the front you don’t pull air through the muffler it’s not an air filter
Pulling air through something is not the same as pushing air through something
Pushing expands air and makes it tumble on it self and slow down
pulling air makes it want to follow a straight path and not tumble on its self
That muffler acts like a sorta Venturi speeding air up when it’s pulled through it compared to the straight pipe
That muffler test makes no since
Blow air through both and bet the straight pipe wines
There’s not one dyno muffler challenge on you tube where substituting a muffler for straight pipe made more power
Snake oil and lies
Straight bs
The proof really is in the chocolate pudding.

How did the spin tech perform? I need the highest flowing mufflers possible. I was recommended straight through but don’t like the sound of them.
I have spintech 6000s on my 318 dodge love the sound and it runs good with them
Throw it on a car and do it on a Dyno
It's been done, Fry burger did it on speed Secrets? Or what ever that show was.
Bogus test? let’s see a normal cars exhaust length , 5ft or more of pipe with and without the muffler and retest
😂😂😂😂😂😂😂

A lot of Gobley goop could’ve done that whole thing in two minutes. No actual proof to back up what are you saying
Go study static & active pressures on tubing, pipe & ductwork... Y'all might come away with a reason for those headaches, lol!
Go watch fry burger show. If this was over or under your head. They tested on a Dino with all different mufflers.All different length exhaust. 👍
Your full of it. It flows more because your comparing a 5-6" of pipe and a larger chamber vs all pipe
