(on behalf of) My girlfriend just bought a 2009 cbr125r, its so quiet u can barely tell its running (only 82 decibels factory), it looks cool but she wants an aftermarket pipe to make some noise. Any ideas where we should be looking/phoning to get an aftermarket pipe? (we are in christchurch) Also is it worth replacing the exhaust all the way to the head and getting a better air filter in search of a wee bit more pep? I assume being fuel injected, decreasing restriction to the "breathing" of the bike will increase power without having to tune it like a carberetted bike...
