I have the Apex-i World Sport, Not ricey at all. Just a nice deep tone that looks great too. Much like the RS-R Ex Mag
The greedy EVO is nice just like the WS and RS-R in low RPM's, but once you punch it with the EVO it sounds ricey. Also I have noticed that the EVO's polished muffler turns dull and yellow (at least two of my friends, and a third getting close to it) over time
