The RS-4 Twin Pipe kit was previously only available as a custom system for Kevin Schwantz who was passionate about these pipes on his Super Motard. He wanted his motorcycle to look like a "Hot Rod" and have a "cool" factor. Yoshimura obliged and one of their most sought-after-yet-unobtainable pipes was created, which was not available to the general public, until now.
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...but that's what Kevin wanted! The pipes have a stainless steel header and "Y" pipe mated to twin aluminum RS-4 mufflers for incredible looks and performance. The kit also comes with a custom Yoshimura kick-stand.
