A full exhaust will quiet it down a lot in the cab. I prefer MBRP over Diamond Eye, but that's only personal preference due to having used them so many times.

MBRP vs Diamond Eye exhaust system
2006 F350 CC DRW 8ft bed
Primarily tow ~11000lb fifth wheel (2011 Laredo 321BH)
The beast has popped the weld on the original to us exhaust and is in need of replacing. This is a workhorse and definitely not going to win any shows so I'm trying to keep it cost-efficient ($300-$450 max). Both MBRP and Diamond Eye offer comparably priced turbo back systems and I'm wondering what real-world advice can be given.
I found a few videos of idle and light acceleration but there isn't a lot out there for loaded heavy tones. And we have the towboss with the 4.30 gears so we run high RPM.
The old system had a muffler but I'm not really sure what system it is to compare. I'll try to look at the muffler tomorrow for a name.
I'm confident I don't need the 5" exhaust since I'm "oem+" and not racing it. Do the high flow mufflers make much difference?
I'm debating 4" turbo back straight pipe with muffler vs without.
Performance-wise:
- EGTs, I'm thinking there won't be much change with or without the muffler going to the 4"
- Maybe a little more power with the larger downpipe,even if it's 3.5" I've seen some listed at.
While I like the dump pipe sounds with extra bark and whistles under the cab, I'm curious how much it would change if I straight pipped it out the back. Will the rare family conversation still be an issue? Or, the exhaust drone when cruising loaded at 2100-2500 RPM (65-70MPH).
Here's the pair for reference:

Thanks. I should have started it with a poll. I added it and notched 1 for you
Which MBRP did you run?
Here's the ones I was looking at:
MBRP
Straight- MBRP 2003-2007 Ford F-250/350 6.0L 4'' Turbo Back, Single Side Off-Road - no muffler -- S6212PLM
Muffled- MBRP 2003-2007 Ford F-250/350 6.0L 4'' Turbo Back, Single Side Off-Road -- S6212P
Diamond Eye
Have to select options- Exhaust Systems | 2003-2007 Ford Powerstroke | Diamond Eye | Thoroughbred Diesel
The biggest between the two is;
Diamond Eye has a 4" down pipe, mbrp down pipe is actually 3.5".
I have the Diamond Eye 4"straight pipe.i was contiplating a muffler, but after I heard it, I said forget it. It sounds tough, but doesn't kill you in the cab.... Roll the windows down going by a fence though
.
You can beat the price of the site listed by a few $$, if you want to shop around.
I had a buddy help me put mine in, which I'd recommend, but it's not really necessary. We did fit, cut, fit, remove and then fit again. Then I clamped everything down (welding would be better, of course).
I do run a tuner and I think after the install, the stick tune feels a little laggy, but it could be because I've been running a tune for so long (I rarely run the stock tune and never more than a day).
What ever you do, you'll like it. Go stainless in the rust belt, otherwise aluminized steel is just fine.

I have the 4" MBRP system I picked up on eBay for $300. It's been on for about 9 months now. No complaints here.
Sound is great.

Performance is one thing but at MBRP we believe that appearance and sound is just as important. Every MBRP performance exhaust system has been specifically tuned to get the optimal sound from your pickup.
