Don't know if you still want the stock headpipes or aftermarket, but Hindle (Canada) has BN Header & Mid-pipe available in low or high-exit at a discount. In addition to the header & mid-pipe, you then have to add a silencer, which they have many configuration and finishes.
Look under Blow-out sale on the main page:
