The Yoshimura RS-12 Full Exhaust System is a complete header-and-muffler replacement for KTM and Husqvarna machines, built with a stainless steel header, an aluminum canister and a carbon fiber end cap.
KTM and Husqvarna share an engine platform, which is why a single Yoshimura system covers both — the badge on the tank differs, the exhaust flange does not.
The full system is where the real change lives. A slip-on alters the last section of the exhaust path; a full system replaces the header too, and on a four-stroke off-road bike the header does as much to determine where in the rev range the power arrives as the canister does to determine how much of it there is.
Fits KTM and Husqvarna applications. Confirm your exact model and year against Yoshimura's application chart before ordering. Check the sound and spark arrester requirements for the land you ride — a separate Yoshimura spark arrester insert is required for USFS and BLM areas.
