I have the SS unresonated x-pipe and the SS race muffler canisters, and felt zero discernible difference in power. In unopened/untouched NA form, the S54 with MSS70 ECU pretty much only gains power by changing out the 2-to-4 catalytic converters (depending which market your car was produced for), along with a tune. Every other bolt-on mod is trivial unfortunately. And anything more than that (altering engine internals) requires significant investment in terms of time/cost
