KTM 390 Duke | Chamber Delete | 2021-2023
This link pipe allows you to remove the heavy muffler/chamber that sits inside the swing arm of your 390 Duke. This does not delete either of the catalytic converters located in the head pipe. Competition Werkes will not be making a replacement head pipe. This Chamber delete will work with both the stock and aftermarket rear canisters.
Off-road use only, not street legal
