Yoshimura Alpha Stainless Slip-On Exhaust with Carbon Fiber Muffler | Kawasaki Ninja 1000SX 2020-2024 / Ninja 1100SX 2025-2026

The Yoshimura Alpha Stainless Slip-On Exhaust is a bolt-on muffler for the 2020-2024 Kawasaki Ninja 1000SX and the 2025-2026 Ninja 1100SX, pairing a stainless steel header pipe with a carbon fiber muffler sleeve, and mounting directly to the stock header with no ECU remapping required.

The Ninja 1000SX is a sport-tourer, and its factory muffler is sized accordingly — large, heavy and quiet. The Alpha canister replaces it with a tapered carbon-sleeved unit that cuts weight from the tail of the bike and gives it the inline-four voice the chassis deserves, without turning a comfortable touring machine into something antisocial.

Kawasaki carried the same exhaust mounting across the Ninja 1000SX and its 1100SX successor, which is why a single part number spans both models. Installation is a straightforward bolt-on against the factory header.

• Bolt-on slip-on muffler — retains the stock header and mid-pipe
• Stainless steel header pipe with carbon fiber muffler sleeve
• Tapered Alpha canister profile
• Bolt-on installation with no ECU remapping required
• Meaningful weight reduction over the large stock muffler assembly
• Yoshimura part number 960-13018 (manufacturer part 14161BP220)
• Made in the USA by Yoshimura R&D of America

Fits the 2020-2024 Kawasaki Ninja 1000SX and 2025-2026 Ninja 1100SX as a direct bolt-on to the stock header, and is the standard exhaust upgrade for riders wanting to lighten and uncork a sport-touring Kawasaki. Check your local sound and emissions requirements before fitting.
