Yoshimura RS-12 Signature Series Full Exhaust System | Stainless Header with Aluminum Canister

The Yoshimura RS-12 Signature Series Full Exhaust System is a complete header-and-muffler replacement built with a stainless steel header, an aluminum canister and a carbon fiber end cap.

Signature Series is Yoshimura's top tier, and the distinction is build quality rather than a different design. It is the same system produced to the standard that goes onto the factory race bikes, instead of the cost-reduced version that fills most of the catalogue.

Underneath that, it is an RS-12: Yoshimura's current off-road canister, shorter than the RS-9 it replaced, with the mass pulled in from the back of the bike. And as a full system it includes the header, which is where the change in power delivery on a four-stroke actually comes from.
