Let me ask you this....Was your truck properly tuned for each setup? Doesnt sound like it was. Seems that it would make sense that the stock setup would produce the best results with stock tuning because it was tuned for that setup. All too many people throw on free flowing exhausts then complain about the loss of low end power, and they didnt get the engine properly tuned to compensate for the added air movement and are then running lean at certain areas of the RPM range.
Theoretically if you compenstate for the added air movement/velocity by adding more fuel you will see gains. Off course your truck could always be some weird exception. Kinda how, to you, the Magnaflows produce a popping noise whereas they dont for anyone else.

My Magnaflow produces a very smooth rumble through all rpms, with no weird popping noises on or off the throttle.

Its all about preference on the sound issue. I can't change your mind on that (even though you are clearly hard of hearing lol) Do what makes you feel good about your truck. Im just bustin yer *****.

 

yea yea ha

 

alright well again im going to ask, WHAT ABOUT the pypes violator, hooker max flow, or the cherry bomb vortex mufflers?

 

^ Junk, junk, and... junk. There is a really good reason why Mangaflow, Borla, and Dynomax bullets are so popular here. They sound good, period.

Roll with it!

 

Well actually to an extent yes. When I was filling out my order form for a custom tune I had listed a free flowing exhaust past the cats but I didn't do dual pipes. After the cats, the "Y" is the highest point of restriction (yes, MGD, I screwed up on that earlier) so anything past that didn't matter as much. I test crossed the 1/4 mile times of just stock (with and without mufflers) then custom tune (with and without muffler). The results were still too close to base a decision off of even though the stock muffler had been that .1 seconds faster and not nearly as obnoxious as without a muffler. The deciding factor was my gas mileage and how poorly it dropped without the muffler. My city mileage stayed the same but it was annoying listening to how loud it was and highway was consistently lower by 2-3 mpg. I wish I still had the sheets for proof but I dont so you'll have to take my word for it.

Bill at PHP has told me different trucks run differently and respond differently to tuning and mods. What works for one person doesn't always work for another.

I'm the one who is hard of hearing? I'll get a vid put together of exhaust clips and compare that to some of the magnaflows on YouTube

I haven't heard the others in person but for the cherry bombs, it depends on how well you mount them. I've heard ONE truck sound really good with them and others sound really, really bad with them.

 

.1 second is easily attributed to a lot of other factors aside from the muffler. There is too much human factor involved to say one muffler setup made .1 second difference. You say you don't care for going with mufflers that are dyno proven to give more power than other designs, yet you are putting stock in quarter mile time differences that are miniscule enough to be attiributed to human error? Man I could go back and forth for days on this but I'm gonna leave it alone at this point. And you are basing sound of mufflers off of youtube videos? Really?

 

Yeah, that is why I then considered the differences in fuel economy. I didn't what to be stuck with a muffler that got me poor mileage when there was a noticable difference between a regular pipe and a chambered muffler. You have to admit that even just 2 mpg is a pretty big difference considering what was done. I drove over 1000 miles with a flow through exhaust from the cats.

No, that was a joke dude...ok I fail at humor today. No I really swapped about a dozen mufflers on about 4-5 trucks (2 dodges, 2 chevys and another Ford) plus asking what people had when I heard a sound I liked. All I remembered was my favorite was the flowmaster with magnaflow being a close second. Then price came into play and the flowmaster also won out against the magnaflow.

 

MBRP. Sounds good to me. This thread really didn't pay off. Sadly it's just opinions.

 

I read that charts too (like: http://www.mustang50magazine.com/tec...o_numbers.html) .... the Flowmaster and Magnflows are so close that no one here is going to know the difference in real; world driving or power pulling that camper or horse trailer or in 1/4 mile ET / speed.

It comes down to sound preferance.

 

 

Could you fix the link ? I want to see it.

I believe M5M also tested torque/power difs. Like a shoot out, some time ago. Borla topped the list that time.

 

Did we answer your question??

 

 

What else do you expect when the question is basically "why is everyone on here so biased toward Magnaflow"? In forums 98% of the info that gets tossed around is opinion.

 

I just now clicked on it and it worked? It appears shorter but it works.
