The DPF adds about as much backpressure as a muffler. Ask yourself if you would expect much change if you installed a muffler-back system, because that's effectively what a DPF-back system is. There are videos of these EcoDiesels running with the exhaust detached after the DPF and they're still quiet.
As with everything, it's your money. However, if you install a DPF-back system for increased tone then you're very likely going to join the others who did the same and were disappointed.
