I am thinking of taking out my muffler. I have 3" exhaust from the turbo back. How loud would it be if I took the muffler off and simply ran 3" all the way back? How much difference would it make in performance? Keep in mind, the wife has to ride in it from time to time. Side note, trying to get me signature up with info, but unable. Any suggestions?

 

take it out! it will be a little loud when you hold it to the floor, but the turbo chops alot of the sound up, but if its real bad about noise pollution were you live then you might not want to.

 

If I remember right yours has a turbo. If so I'd straight pipe it. It isn't bad at all.
My truck is a '94 so I think it has more sound-deadening but It isn't any louder inside while cruising or idling. It's only louder on hard exceleration but it sounds GOOD!
There's a Jake-brake sound under hard compression braking but I like that too.

My Powerstroke is straight-piped too and it doesn't sound nearly as good.

 

Its loud at high RPM. Its not any different in the bottom end, Except for a little more drone.

 

It must be cab/body style/insulation differences because mine is not obnoxious at any prm/speed and you can't even tell the difference until you hit WOT.

I'd pay attention to what the guys with your body style say though.

 

Go for it, they really aren't that loud. I ran a base '94 for awhile with a straight pipe and with the windows up you couldn't hear the exhaust in the cab.

 

I have mine striaght piped and it is a little loud under exceleration but still sounds good. Will be better when I get the 3" pipe on it.

 

I just did mine yesterday like everyone said turbo chops up exhaust pules. only when you put your foot into will you feel and hear the difference.

 

weird.

I put 4" straight pipe all the way back on mine initially (after the 3" downpipe) and it was loud and blatty as hell.

 

thats wierd ghunt, cause my dads non turbo 7.3 dont have the muffler and its not horrible loud its a little loud with a load and wot but i like the way it sounds, it does favor a big block gasser but i like it.

 

just do it you will like it

 

Is that unmuffled with the stock exhaust & downpipe though? That might be the difference, I dunno.

When I bought my truck it had the factory 3" exhaust with a 3" straight-through Magnaflow installed on it. It was super quiet, but I figure that smashed stock downpipe doesn't let a lot of sound out either.

 

its a n/a 7.3 with the stock restrictive y pipe, muffler unbolted from the factory location and taken off

 

Even as deaf as I'm getting, that is too loud to drive every day. I like the sound of a good, loud exhaust, but a straight piped NA just sounds like crap.
There is a nice rumble at idle, but too rappy anything above that.

everyone just has a differnt way they like there vehicle to sound, i like mine to **** people off not only cause its loud but i can also blow smoke if i want to
