I don't think u need that many upgrades to have a nice sounding exhaust. its truly all about pairing things up the right way, without compromising parts that don't belong with other parts.......
I have mild upgrades. I have at least one person at every 4th light say something about the way my car sounds. Now yes I have no blow off valve or winding pulley that really catches your attention
. but I think a full headers back exhaust with the right set up & tuned will give u an awesome sounding Z
