Magnaflow vs Flowmaster

[jimdeforge]

I would like to give my truck a more aggressive sound, it is a 2011 1500 SLT 4.7l. I am debating on which muffler is better, Magnaflow or Flowmaster and then which model would sound best? Does anyone have a suggestion? Any help would be greatly appreciated!

I have a 5.7L with a Magnaflow 3' in two 2.5' out muffler and it gives it a deep low rumble which gets louder through the rpm range. I also cut the factory exhaust right after the junction of the cat's to allow as much flow (and noise) as possible. On the other hand, my buddy put a Flowmaster on his F250 and it sounds like a coffee can with a tailpipe coming out of it. I recommend the Magnaflow if you want a good low bark for your truck. Also since it is a 4.7L I would be tempted to leave it a single 3' to maintain a little back pressure since my 5.7L has very little with the dual setup (This completely messed up how my truck shifted and performed overall until I installed a Superchips tune).

Op check this thread out. Might have some 4.7 sound clips in there.

Thanks, what I plan on doing to the truck is put a K&N 63 Series CAI in it then replace the stock muffler with a flowmaster or magnaflow muffler to give it a better sound and hopefully gain a little mpg's as well. I wanted to keep my cost as low as possible, getting the biggest bang for my buck!!!

Thanks. I actually joined to get a few questions of my own answered and ended up in the new posts trying to make one. Figure that.

I actually did the same but if your looking to save a little cash check out greenfiltersusa.com - greenfiltersusa Resources and Information.. I ended up getting a cold air intake for my Hemi about $150 less than a K&N and the tests show they make more horsepower. The mpg gain isn't greatly impressive, I only saw about 1.5 mpg increase with the intake but every little bit counts.

Thanks, they did have some good clips. The only bad thing is none of them were single exhaust like my truck. I can't afford to change it to dual exhaust, wish I could.

They don't make a CAI for my 2011

Sorry to hear that. It looks like they stopped making them after the 3rd gens. Sorry about that.

no worries, the K&N 63 CAI isn't that bad in price all things considered. I found it for $288 here: http://www.carparts.com/details/Ram...Intake/2011/SLT/8_Cyl_4-dot-7L/K33631529.html

 

[jimdeforge]

now just to decide on which muffler

 

[jimdeforge]

I do care about price and warranty, from what I found online Magnaflow has the better warranty and price.

Thats a good price. I got my cai for $250 at Chrysler Carlisle and I had been looking at a K&N series 77 for about $400 at the local auto parts store.

I've been partial to Magnaflow ever since we put one on my dads 360 about 10 years ago. The only problem with magnaflow is there isn't much inside the muffler itself so it can get pretty loud, but everyone around here has seemed to switch also since they heard the sound. I've noticed almost every Hemi around this area has Magnaflow duals under them.

I don't care about sound, I take that back, I want it to be aggressive. I am a firm believer in loud pipes saves lives. That is how I roll on my motorcycle!

Loud pipes do indeed save lives, the reason I like magnaflow is because the only diffence between their stuff and Cherry Bomb is a layer of packing and a drilled sheet of metal. The flowmaster may be loud but it doesn't have a smooth sound where the Magnaflows have both.

Here's some youtube videos for you to look at, this guy put dumps on his after the muffler but it still gives a good idea of the sound you would get.

not bad, I really need to hear one in person before buying

I personally like the sound of FM most of the time. However they do tend to drone at certain RPMs. But I would not buy another FM since I have had them rust out on me too many times. FM does make stainless steel versions now, may be worth a try.

Another to consider is Borla. I had an XR1 and loved it.

I had an 18" magna flow on my 03 4.7L ram and loved it(the black on over there <-). I had the single out and cut it at the spare tire. It was pretty loud, but like some other guys have said, its a low growl that I like. The flow masters sound too hallow and "tingy" for my taste. I put the 14" on my 2011 hemi cause the its so quiet inside, i wanted to still hear it, and its awesome.

I wish i had some sound clips from my old one for ya, but i'd go for the magna flow.
