Austin 2026 KTM 990 RCR RS22 DUAL UNDERSEAT SLIP-ON TITANIUM EXHAUST SYSTEM AR100

2026 KTM 990RC-R RS22 UNDERSEAT SLIP ON

TITANIUM dB COMPLIANT EXHAUST SYSTEM

The RS22 Underseat Slip-On has been developed specifically for the 2026 KTM 990 RC-R, delivering a sharp increase in sound, presence, and visual impact while retaining everyday usability. This system allows you to keep your stock headers in places, therefore keeping the standard emissions controls and volume down. 

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

Tested and certified to UK dB conformity and will be supplied with a certificate and laser etched eNumber on the silencer. This will help with riding within mainland Europe.
