The Yoshimura 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 “Twin 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 DR-Z400SM... but that's what Kevin wanted! The pipes have a stainless steel header and "Y" pipe mated to twin RS-4 mufflers, in either aluminum or carbon fiber, for incredible looks and performance. The kit also comes with a custom Yoshimura kick-stand.

We have this system installed on our 2016 Suzuki DR-Z400SM Project Bike and really like the unique look it gives the bike...there really is nothing like it available on the market. The fit and finish is beautiful, and it sounds great. The tone is very similar to the Yoshimura RS-2 system, but its slightly louder with a little deeper overall sound. If you are looking to set your DRZ apart from the crowd, this is definitely the exhaust system to go with.
