What sort of area do you live in? I'd go for a bit more volume but I live in a 15 house cul-de-sac and the neighbours would not appreciate anything more than TORS. If you think you can get away with it, take a gamble and go for something different. If it doesn't work out, I'm sure someone will swap with you.
I got this information comparing relative volumes of various pipes from TRat.net. It was written by our very own Pat (Dinqua); I hope he doesn't mind me reprinting it here:
(Loudest at the top)
Sceptres
JC Whitney Open Pipes
D&Ds
Bubs
Thunderbike Pipes
Epcos
Specialty Spares
TORs
Stockers
(This is one persons opinion.)
Don't forget, you're not just limited to pipes made for our bikes, you just need to match up the pipe diameter where the header meets the silencer. (Do a search for the size.)
Or just debaffle the stock pipes.
