All I know is that I love my maggie....very high-flow, and the perfect sound....not too loud not to quiet, not aggrivating, and it never pop's!

I had flowmaster on my ranger it was great because it was just a six but magnaflow definitely performs better on my f150 and it sounds awesome!

 

Crap can? Have you ever cut apart one of your precious Flowmasters? A few pieces of tin spot welded in the shape of a V inside a thin piece of cheap stainless that rusts out in 3 or 4 years. Woohoo.....

If you won't believe someone that's done the dyno pulls on the different exhausts, there's not a damn thing that anyone here outside time/date stamped pictures holding up the results will say to change your mind. You would probably accuse them of fabricating the whole thing even then.

You are obviously biased to Flowmaster because you either have reading comprehension problems or you sell the things.

Here's one for you.... go spend your dime on a dyno to test them both out and then you can call people liars about what their personal seat of the pants experiences are. Until then, everyone here has an opinion as valid as yours and the numbers are against you.

I personally could give two squirts what you believe.

 

If someone wants i have 2 flows laying in the garage that i am willing to cut open because they will never go on another vehicle of mine!!!!!

Yes baffles restrict power over straight through!
This is a never ending battle
Hers one for ya put the same parts on identicle vehicles except exhaust.The truck with the maggies will show the one with flows the tailights.

 

I've had a few. Had them on my big block and had them on my V6 with small blocks in between. Saw the biggest improvement on the 460 BB, and it only runs on torque. Flowmaster original 40 passed the burnout test on that truck. Wouldn't do a burnout from a dead stop and now it does it quite well, and I need new tires. I had an entire system made though, but I can still say that I have proof on my driveway that the Flowmaster improves power.

Im not saying that the magnaflow causes power loss. I know it improves power, but the flowmaster improves power too. I don't think that either are bad mufflers. Mags are made of stainless and flows are made of aluminized. Stainless is a better material for dealing with long term salt conditions.

The baffles actualy help scavange gasses. The baffles are a V shape and when gasses pass by the V is causes a ventury, and it almost works like a vacume.

Flows have the crappy V baffles and mags have the crappy cotton ball packing. (not really made of cotton). This will never end . I want to see dynos of two exact vehicles, one with mags one with flows. You cant realy race them because the drivers would vary results.

 

flowmaster sucks end of story. I wish i could get my money back. I would rather someone $100 bucks to take me out back and beat the **** out of me with a louisville slugger than buy another flowmaster muffler

 

That's funny^^^^^^^^^^^^^^^^^^^

06STX a 460 huh
I dunno i guess every truck is dif but i know it did not work well for me.I don't need a dyno to show that anywhere i hit the gas it has better throttle response by alot.The main place i notice is at take off and mid range

 

Exactly.......now back to your regular programming!

 

so it sounds like most people are in agreement that Mags will give you some low end and Flows will take that away. So with that established- why do people buy the Flowmasters?

I am asking this question because I plan to do my exhaust in the next two weeks. If Flows give a more aggressive and throaty sound, I would almost live with the low end loss. It sounds like the Mags might not be loud enough?
Is that why there are so many people with the Flowmaster?

 

People buy flowmasters for their distinctive sound, but I prefer the magnaflow sound. The low wnd torque is a bonus.

 

Couldn't stay out could you. If you like a throaty sounding exhaust, not too loud but is definitely there, get Flowmaster 40. If you want to barely realize you have something more than stock, get a Magnaflo. They get Flos for the sound. I would not have anything else.

 

From an old man who can't hear, magnaflow mufflers aren't loud, but mine is because I still have my hearing.

 

I hear well enough to enjoy the sounds of a nicely tuned engine exhaust and a lover during sex. What else is worth hearing?

 

Oh, wow. Do you know what TMI is?

 

Then quit berating us "old farts".
