Yoshimura – RS-12 Slip-On Exhaust (KTM)

Born from over three years of factory-level testing and refinement, the Yoshimura RS-12 Slip-On Exhaust takes KTM performance and sound to an entirely new level. Designed in collaboration with top pro riders and Yoshimura engineers, this system is all about real-world gains — stronger power, smoother throttle response, and a more centralized mass for better handling.

At first glance, the aggressive asymmetrical muffler design sets it apart, but it’s the details that make the RS-12 truly special. The matte carbon fiber end cap with embedded decal inlays, the precision-machined joints, and the tapered muffler body inlet all come together to create a slip-on that looks as good as it performs. The patent-pending Precision Taper Fit (PTF) insert ring makes insert swaps and maintenance easier than ever, while the internal tuning delivers the unmistakable Yoshimura tone — clean, deep, and powerful.

Why We Like It:
It’s a perfect balance of performance and craftsmanship. The RS-12 gives KTM’s already aggressive powerband more punch and refinement, with a tone that’s rich without being obnoxious. Every weld and curve screams race pedigree.

Why It’ll Work for You:
This slip-on gives your KTM sharper throttle response, more midrange pull, and smoother delivery from corner to corner. It’s lighter, easier to maintain, and designed to fit perfectly with your stock header. You’ll feel and hear the difference the moment you crack the throttle.

Variants / Options:
Compatible with OEM or Yoshimura headers. Available with matte carbon fiber end cap and brushed stainless or titanium canister depending on model.
