Same set up as what many other manufacturers have
Most muffler shops can do something for you, and the advantage of the Aussie made ones are that they are "universal" and will ensure that the noise level is below the WOF threshold.
I have seen this done a few times to BH/BE, BM/BR, BP's etc ove in Aus as the mufflers come in a range of sizes just talk to your local muffler shop for ideas...
Yeah I was thinking of going down to pitstop, although I'm sure they'd tryn push their brands in.
Thing with mufflers is, I kinda need to hear what its like before fitting it in, guess I'd have to take their word for it..
