Thank you Hydra and Indy for your replies. This explains a few things for me on what I need to do now.

 

Your welcome. Good luck with the choices and the install.

You aren't comparing apples to apples!

This guy didn't install just a Flowmaster Muffler and Dino it, then install a MagnFlow and Dino. You are comparing a entire Magnaflow system to a Flowmaster muffler! You can get an entire Flowmaster exhaust system as well? You could just replace the muffler either way dude!

Not to mention what were the actual numbers torque and hp as well as power charting. Ya, he could lose hp but what about torque along with the other info? This is a biassed opinion with no actual vaules or data to back it up........Give up the numbers?

 

He took a fairly new stocker setup, replaced the ENTIRE thing (a full cat back), not just the muffler, and lost his *** on the dyno. NOTHING improved. Magic was there. Ask him!

Magnaflow SOUND nice. Flowmaster sounds AND performs nice. Fact. Pick what you want... sound or sound and performance. Just because you have it doesn't make it the best choice. Sorry to **** on your beloved Magnaflow.

Just sayin that if you can replace the muffler you could go either way. Also you could do full system on both as well, it's the same thing.


But again you arn't compairing apples to apples and I'd like to see the graph to see any improvements and where they are ya know? The dude lost 2 hp but what about torque and power band, ect? You can't just slip on a exhaust and that it and expect a masterpiece? Also not dissin your your truth because I don't think I should my friend, just lookin for the graphs?

 

Honestly HS, I have no idea what you are comparing or talking about at this point. The guy asked about a replacement muffler for something better. After he was suggested the Magnaflow, I provided info on a Magnaflow to Flowmaster comparison with a real world Magnaflow story.

The story has the guy who was pissed when it happened. I doubt he went back from Carlisle and posted any charts for the world to compare. He was last seen headed back over to the Magnaflow tent to have a "discussion."

Again, the only thing he gained was sound and high blood pressure from being pissed. No HP, no Torque, no Performance Gains.

Chrysler most likely tuned the exhaust in on that model and he went and messed around with it without knowing what he was doing. He though he could just add a new system to it and have a masterpiece. Were he went wrong was that the car was already tuned in. Had he installed a Flowmaster setup he would have ended up with the same numbers I'd bet. Sounds like this was a classic screw up on his part.

Some vehicles have already been dialed in thus only removing the muffler for better sound would be warranted for better sound. However, if this guy does some intake work or other exhaust work like headers and intake work it will flow differently. The new system would work better than the old.

Most people think they are going to get HP and torque out of their trucks like what everyone tells em.......AKA......You'll get 15 hp and 33 lbs of torque using my system!......Thats totally BS! It never works out like that but the power curvature will change and you might get more HP and TQ. There is more than meets the eye on those dino records!

To prove this point I will look up and old old build that Horse Power TV did then dino'ed and they got 15 HP......You'll crap your pants to see what they did to get it!


Whether it's MagnaFlow of DynaFlow or Flowmaster, all work differently and what it really comes down to is a few numbers but mostly personal sound and choice.

 

As the creator of this thread I am asking IndyDurango to provide the numbers for the test. You Provide no evidence that the Flowmaster preforms better.

 

I couldn't find the episode I was looking for but this could also be something to look at. http://www.powerblocktv.com/sites/bang4buck/0704/ Your talking about only a 14 hp and 19 lbs of torque! Now look at the curvature of the now NEW graphing in comparison to the old. This is the difference I'm talking about not just the loss in overall hp that you are going after. Hell, in OEM it's producing only 140 hp at 2500 rpm and after the mods at 2500 rpm a whooping 300 hp! Thats apples to apples.

So ya, your boy lost a whole 2 hp in overall horse power numbers but what did he gain in power curve? Performance and torque during the power curve is what wins races and towing, not overall numbers!


Just in case I also want to clear the air. If that guy would have replaced just the muffler to either Flowmaster or MagnaFlow or any other brand for that matter, it most likely would have pulled the same numbers. I just really like the flow of MagnaFlow a lot better than Flowmaster and the sound comes as a plus.....IMHO.....But each to their own.

 

HS, What part of the "HE WAS AT THE MAGNAFLOW TENT BUYING DIRECTLY FROM THEIR EXPERTS and he ended up GAINING NOTHING do you not understand? Since you have a Magnaflow, you must be 'thread blind' or something refusing to think just perhaps you didn't get what you thought you got. God forbid! And as a Mod here, since FM is a sponsor here too, I would have thought you would give them a bit more love.

It wasn't MY test. Where did you read that I had numbers? I said it was first hand personal observation at the All Chrysler Nationals this July with other members of this forum there to see it too. I am telling you FM is better than stock AND that MF did nothing on a first hand observation. You can search and get all the other data you want.

With that, I am done "helping". Go ahead and tread blindly and buy what you want Pal. Good luck and enjoy your new muffler of choice. It's King Kong vs. Godzilla, Charmin vs. Cottonelle. Both are monsters, both will supposedly wipe a stock muffler's ***.
