The RS-4 Twin Pipe kit was previously only available as a custom system for Kevin Schwantz.

Yoshimura is offering these incredible "Twice Pipes" which are completely fabricated by hand and TIG welded to perfection. They certainly sit at the high end of what is available for the mighty SM... The pipes have a stainless steel header and "Y" pipe mated to twin carbon fiber or aluminum RS-4 mufflers for incredible looks and performance. The kit also comes with a custom Yoshimura side stand.
