Thanks to its Euro 5+ type approval with an engraved certification number, the Sioux III is fully street-legal – for all Chieftain models built from 2025 to 2027.

Your style – your end cap
Choose from three end cap shapes – Standard, SlashCut or Tapered – each available with a high-gloss polished or matt black finish. The Sioux III itself comes in high-gloss polished stainless steel or with a heat-resistant matt black coating – for a premium look and lasting durability.
Mount. Start. Ride.
Fitting could not be easier: the original header with catalytic converter stays in place – simply unbolt the stock muffler, fit the Sioux III and ride away fully legal. All the mounting hardware you need, your approval certificate and the fitting instructions are included.
