2017-2023 KTM 390 Duke Chamber Delete by Competition Werkes


  • Removes main chamber/canister
  • Does not delete stock muffler or catalytic converter
  • Compatible with any slip-on designed to fit the stock exhaust
  • Reduction in weight and mid-range HP gains.
  • Increase in exhaust dB level.

Please note: The Australian KTM 390 Duke uses this model for 2017-2023 and not the 2020+ variant seen in the US - due to the exhaust difference.
