Magnaflow or Flowmaster?

[dhyde79]

so, I want a dual in-single out muffler, and am torn on which one to get.

I want to keep the tone mellow, volume stock or as close to it as possible, and I want to avoid the "ricer" sound as well as the "forced air" sound that I've heard on some magnaflows at higher RPM's...

I'll take any suggestions that ya'll have, thanks in advance!

i have a single champer flowmaster. its great. calm collective sound even though i'd like it to be louder. no ricer sound at all. just a deep noise. i've also had problems with magnaflow rusting for me and breaking :/ not one flowmaster has done that yet.

I have a flowmaster 40 single in single out. I love the way it sounds. I used to have the 50 series that was a bit quieter.

I have the flowmaster 50. Sounds great. No rice.

The Flow master is an echoic muffler that uses chambers to baffle the noise.
The Magnaflow is a straight through muffler with packs to muffle the engine noise.
Or at least this is the way the Muffler guy explained it to me.

I have the magnaflow (dual in/single out) and thought it was loud at first, and now I like it. I had a Flowmaster 40 (single in/ single out) on my 1st Gen and after a while I didn't notice it at all and thought it was too quiet.

I have a MagnaFlow XL muffler (#13256) on my Frontier and I love it. Nice mellow tone with zero droning.

From MagnaFlow:

MagnaFlow XL Mufflers use an unique combination of large diameter perforated tubing and strategically placed sound baffles to reduce unwanted resonance and help your engine create horsepower.

The sound baffles tune the sound waves using calibrated tuning gate openings that allow portions of the waves to pass through. These tuned waves reflect off the back wall of the muffler and cancel out unwanted harsher sounds.

The large diameter perforated core eliminates the flow restrictions of a louvered style core. A careful balance between perforation size/spacing and the baffle tuning gate make for a great 3 chamber performance muffler.

peck, is it dual in single out or is it single in single out?

 

[Peck]

It's the single/single.

I had a Doug Thorley/Jardine cat-back on my Frontier before that. The Thorley/Jardine muffle is complete garbage and the inlet and outlets rusted off the damn muffler body. So I chose the single in as I already had a upgraded Y-pipe.

My truck used to drone at 60-75mph in 5th but now there is little to no noise at any rpm/speed.

Oh, and it appears I gained 1-2mpg since I have put it on. I track all my mileage and that's what it's showing. Plus I usually fill up Monday and Thursday, now it's Tuesday and Sunday with the same amount of driving.
