As someone who wants the performance of down pipes but wants as much of the factory exhaust sound as possible, do you think the Encore X Pipes will introduce too much of a change in terms of sound?

Similar to the E46 M3 with HFC's, when it's cold the resonance is more pronounced, when it warms up it goes away. It's more pronounced when you shift, but that subsides too. I do not like loud exhausts, and I probably won't be changing the stock muffler.
I would say there is a slight increase in sound while going through the gears passively, but it's a great sound, and pretty much stock like while cruising, and no drone, but great WOT sound, if that's what you are looking for this xpipe with HPC's fits your needs.
