straight through mufflers

Who has a straight through muffler?
What kind do you have; Walker BTM, AFE, Magnaflow, etc...?
How does it sound?
I am getting really sick of my stack. I've had it for 2 and a half years now. It's lost it's novelty, and it's annoying as hell.
I have the pipe and tip I bought from Nick at SSS, i'm going to put that on and I want to quiet the truck down with a muffler. I would still like it sound throaty, just not annoying

Any input?

I just realize as I typed this.....I think i'm getting old

I have a 4" MBRP straight through muffler that I ran for a few months. Definitely less restrictive than the stock but not excessively loud. I took it off in favor of a straight pipe.

How loud is the straightpipe compared to the stock muffler? I want my exhaust less restrictive for gas mileage, but don't have a lot of money to put into an exhaust. I was thinking I could clamp in a straight pipe in place of the muffler, then, when i've got to do the Kalifornia smog thing in 2 years I'd clamp the muffler back in.

Whaddaya think? I don't care for loud or throaty, this is mostly a tow vehicle, all the money and go fast mods go into my other toys.

i also have a mbrp 4" not much louder than stock and no annoying drone. I can't think that it is much more than a straight pipe; when i put it in I remember that is was straight through

Wonder how that Aero 4040 sounds on a 7.3.
Sounds pretty good on that 5.9 in the video, but thats too much money to spend on a muffler IMO.

Thanks for the input guys. I imagine there isn't a whole lot of difference in sound from one straight through to another, but I'm sick to death of the straight pipe and the stack.

Sure looks like a big C to me, hmmmmm...

I have a 4" Magnaflow with a straight through muffler and I really like it. There's no drone at highway speeds but you can still hear it if you don't want to listen to the radio. But it has a good deep throaty note when you mash on the go pedal.

Edit: Also I don't like to listen to the radio too loud and I can still hear it just fine. I promise I'm really not that old.
