2026 KTM 990RC-R RS22 Full Titanium RS22 Exhaust System

Maximum Flow. Minimum Weight. No Compromise.

This full titanium RS22 Exhaust system is designed to unlock the full potential of the KTM 990 RC-R platform.. Engineered for performance first, they dramatically improve exhaust flow, sharpen throttle response, and deliver a noticeable weight reduction over the restrictive stock setup.

Important: An ECU remap is essential when running these headers to ensure correct fueling and safe operation.

This is a twin-exit titanium system, engineered to sit cleanly under the tail and complement the RC-R’s aggressive race geometry. Lightweight and compact, the RS22 offers a properly tuned exhaust note without compromising fitment or rideability.

This system includes the headers and the RS22 decat system, the ATOM unit can be found HERE
