Quiet DPF system??

I have a 4" AFE exhaust/muffler (not installed yet) and was wondering how quiet will this be in the cab. I rode in the 6.7 for a month then jumped in my 6.0 tuned and deleted with a 4"MBRP/muff and realized I don't need two loud trucks. I enjoy the quiet cab of the 6.7.

Will the 6.7 be as loud as 6.0 in the cab or should I get delete pipe with a Donaldson muffler with stock tail section. I wouldn't mind the rumble out of the tail section I just don't want to hear it in the cab for a long trip.

Straight piped was too loud for me and so I got the 51" donaldson. I can still hear a slight rumble and turbo noise, but at freeway speeds or towing, my AT tires are louder than the engine noise. I like it alot.

I have a 5 inch with no muffler and my tires are louder than my exhaust in the cab with the windows up.

Yes! I deleted my truck yesterday and also have the 51" Donaldson muffler. I love it! No wastegate screech whatsoever! There is a nice deep rumble that's slightly louder than stock and a nice turbo whistle that's roughly twice as loud as stock. The wastegate let off whistle sounds amazing! No wastegate coughing noise!

Yes, definitely. I'll probably start a new thread describing and depicting my delete setup. I haven't exactly posted a video on the forum before, but I'm sure it won't be a problem. Once I figure out how, I imagine I'll be popping up videos like crazy.
