You might also want to check with Chris Wedman at Wedman Motorsports. He serviced my 1997 Vmax and I plan to take my 2009 Vmax to him also. Chris Wedman --- Wedman Motorsports --- 9005 NW 10th Street, OKC --- 405-440-1900
Chris races and services drag strip bikes and sometimes is out of town...
I don't know about non-U.S. manufactured Vmaxes, but the U.S. produced models only came with the black factory mufflers in 1996 and 1997. I have a like new set from my 97 that I boxed and stored when the kerker system was installed in 97/98.
