The brake lines are the same for the 03 and 05 bikes. Keep in mind that you're not ordering Triumph parts. They may differ slightly from the OE parts on the bike. This doesn't mean they don't work. It simply means they differ slightly.
Since the Billet Manifolds are a new product for us, I'll defer to the experience of the guys at SouthBay/TPUSA. These manifolds were designed by Matt Capri and have been used for years on these bikes. Please keep us updated on their reply.
