I installed a magnaflow Stainless muffler. its a straight though design just like a Aero.
Mine has no drone. it also has stainless packing as well.

Magnflow has 2 kinds of diesel mufflers Race and street, identical in every way except one. Their street mufflers have packing.

I bought this one 2 years ago (its the longest one they sell)

Aero Muffler

I'm removing my Aero muffler next month and re-installing my OEM muffler. While many folks in this forum love them, I used mine for two seasons and I'm not a fan.

Two reasons: it's exceptionally louder than the stock muffler, at least on my engine. Some folks say it's not that noticeable, but it's too loud for my taste. The main reason I'm ripping it off is the excessive exhaust fumes it allows. The OEM muffler has an integrated cat converter which helps filter exhaust. The Aero is a free flowing muffler, so it does no filtering. The fumes come into play when I climb in my dingy after towing it. The interior of the dingy smells like heavy diesel exhaust. This was never a problem with the stock muffler. When my wife follows me in her car to drop the MH off for service or the like, she has to keep her distance, as the exhaust fumes choke her out.

None of this may bother other folks, but since I've seen no improvement in power, exhaust temps or fuel economy, I see no reason to put up with the fumes.

I took my aero off and replaced with straight pipe. Aero was louder than stock, straight pipe is much louder. I have not seen any improvements also with aero or straight pipe.

Total agreement for some folks, me, I love the Walker resonator, very slightly Lou der than the OEM Cowl design muffler. but to each their own. As for not noticing a n improvement in power, reduced heat in bed room etc, am thinking Might not notice a flat tire either.

Full time since '07

It is installed correctly. IN and OUT were marked. It is MUCH louder than the stock muffler, with a very annoying drone in the 1,600 to 1,700 RPM area. At highway speeds (65-70 mph) I'm right in that RPM range and the drone inside the coach is WAY too loud.

I also did not notice any difference in performance or mileage. I keep very accurate MPG records and saw zero change with the installation of this muffler. It was a big waste of money and time.

Have to open the window to hear anything and drive under a bridge to hear my slightly louder exhaust, since my setup uses the Cummins iSM500, wondering what engine would be so loud, maybe a non insulated box ? With so many enjoying the advantages, sure is interesting. Agree, I do not gain any mpg, I just Arrive sooner as I drive faster enjoying the noticeable hp gain.
