Power wise I don't think there is anything bar a straight pipe that can match it for top end power gain. I kinda miss the noise it made, VTEC through tunnels was AWESOME.
However now I'm about to try something quiet, just have to wait for it to arrive. If you are after performance but don't want too much noise, try Fujitsubo exhausts (Power getter, RM01A, Legalis R).
NB if you do go for a japanese cat back you will need a custom shorter cat; AUSDM stock is about 17" long IIRC and you will need a cat about 12" long.
