The dump is a big part of the drone, especially with a flowmaster...

Personally I replaced my 40 series with an Aero Turbine 3030 and haven't looked back. It's a bit louder when accelerating but when cruising there is very little noise (I have a side exit), it sounds way better too, and better than magnaflow IMO.
Some videos of it, granted I have a 5.2.

I have a magnaflow that is dual sent out to the rear, cat still in place and at times I think it's almost too quiet, however if you're outside the truck at idle it sounds amazing! When you accelerate it really sounds tough! I really can't decide whether I should take the cat off of it, it's my dd so I'm scared about drone in the cabin.

I would say a magnaflow is definently the direction you want to go when it comes to mufflers. Exiting the exhaust out the back or dumping it atleast behind the rear axle would help your noise. Or you could do the side exit before the passenger rear tire and throw a high flow cat on it to help.

 

go with magnaflow! I have one dumped and it doesn't drone bad at all.
Never was a fan of flowmasters, never had any complaint with my magnaflow, get complements on it all the time, a mechanic at the dodge dealer actually chased me down as I was leaving cause he had been playing with mufflers on his 4.7 ram and wanted his to sound like mine.

 

You don't have to get rid of the Flowmaster, just pipe it out the side or the back. If you dump it under the truck, you're going to get drone, doesn't matter which muffler you have. It's just the nature of the beast!

 

Flowmasters are junk. You should replace it with a magnaflow and send it to me so I can dispose of it for you.

 

i went with borla. no drone whatsoever. $116
when i had my rollpan on i had it routed and dumped right at the bottom of the pan, it was hidden unless you got under the truck.

 

That's how I want to do it. How did that borla sound?

 

borla sounds badass. both on my 3.7 and one of my buddies 4.7`s. nice rumble with no cab drone like the dreaded flowmaster.

 

Oh well. I was gonna say Spintech. I still need to install mine.

 

Has anyone here with a magnaflow, or flowmaster that's dumped out the back removed their cat? If so did doing so create drone and more noise inside the cab? I'm thinking of deleting my cat but am leery to do so because my R/T is my dd and I don't want anything annoying. :drive:

 

I had my magnaflow 14" with my cat removed on my durango 5.9 a year ago, it droned a little bit, but on the highway, nothing. Best sounding truck i've had. I miss it too. lol

 

Another vote for magnaflow.

 

I think cats do help with the resonance. I would try to dump out the side or back. Less drone and exhaust fumes. I have a Flowmaster 40 on a full exhaust and it's still obnoxious. I placed a Dynomax straight-through in front of it and it helped with the drone considerably. I put an exhaust cut-out for loud and less restriction. I would go with Magnaflow or Borla.

 

I think I'm gonna go with a single 3 I/O magnaflow and run a single 3" dumped out the back.

Duals are just for looks anyway, unless I go true.

It's a nice way to get the sound to the drivers side too.. I like riding in the passenger seat in my truck because the exhaust sound so much better, I plan on going duals eventually.

I think you'll be fine with a 3" single.

 

Get rid of the Flowmaster, besides the drone, they are one of the worst flowing performance mufflers.

 

People's opinion on mufflers are just like their opinions on which motor oil or oil filter is the best. Take the information you have and make up your own mind because you have no one to please except yourself.

 

I know that, I just want some options to choose from. Seems like straight through is the way to go for the elast amount of drone.

 

I went with a Gibson Dual Sport side exit cat-back exhaust and couldn't be happier. Can't recall where I got it from anymore, but it sounds great when you get on it, but doesn't drone on the highway. Problem with exhaust is "good sound" is in the ear of the listener...
