6.7 exhaust

I guess (not to steal the thread) what i'm looking to be answered is does the egr being off make a noticeable difference in the sound of the exhaust, whether it be warming up or driving? cause I've heard quite a few 6.7's without dpf's but various ones with egr deletes and some with them still intact and the ones with the egr intact seem to make less noise and sound less throaty
