i meant greddy evoIIs, not the evo lol my bad... and im just not sure how an exhaust will sound n/a compared to turbo(besides the fact that it will be quieter). For example, i find the greddy evoii to be obnoxious witha k-series motor, i prefer an rsr or greddy sp2 sound. Unfortunately the piping size of these is 2.3", and I've been told thats too small for FI applications.
