No muff too loud?

Hi all. Just got an 03 F250 w 61k miles on it. Don't know much about diesels as I was a die hard small block chevy fan and builder. I put in a low restriction air filter setup already and want to go w 4" turbo back (probably diamond eye). My question is, will it be too obnoxiously loud w/o a muffler? Was also tossing around the idea of getting a 6 position chip for it but don't want to cause any premature engine issues. Thanks

Not sure what 7.3's this guy ^^^ is listening to but all straigh piped 7.3's ive herd sound awesome!
Can hardly hear the exhaust with windows up and just cruisin but if you open the windows and get on it it sounds great!
If you like the whine of a turbo you will enjoy a straight pipe.

Go to youtube and look it up. You can get an idea of what it will sound like.

I would hate to see the thing that farts like a 7.3 sounds. Mine is straight piped and I love it. As stated before, not too loud in the cab, sounds great with the windows down, may be super loud to everyone else around you but shouldn't bother you.

The issue with a straight piped 7.3 and most v8 diesels Ive heard is that they tend to have a bit of a flutter that some folks dont like...... I personally like the way mine sounds, and it doesnt have nearly the drone in the cab my cummins had.

I like my straight pipe. At idle the noise level is equal to the engine. Depending on where you stand you either hear the engine, the exhaust, or both if you stand just right. I have 4" to where the cat would be, 5" the rest of the way out. It is in no way comparable to a gasser running straight pipe.
