Thanks FrankenFrankenstuff!
The header does look the same, so it probably will be (the header came with the bike when I bought it). Unfortunately, when I bought it, the front wheel could get caught between the middle header pipes while braking. Extremely dangerous... SO I had to make them a bit shorter.
The bike came without a muffler, so I made one using perforated tubing and the shell of a Virago muffler. Sounded like this:

. So I made a few adjustmenst and now it sounds prefect (imho).
