At DMG Motorsports, we present the Yoshimura Street AT2 Slip-On Exhaust (SS-SS-CF), part number 14730BP520 — a race-bred stainless steel slip-on built for the Kawasaki Ninja 500/Z500 and compatible with the Ninja 400/Z400. This is the next evolution of Yoshimura's legendary Alpha Taper muffler line, blending an aggressive, faceted carbon fiber end cap with proven Yoshimura race technology to deliver a noticeable jump in performance, a dramatic reduction in weight, and that unmistakable Yoshimura exhaust note. Designed and manufactured to extremely strict tolerances in Chino, California, this Street Series slip-on bolts directly onto your stock exhaust system with no emissions tampering required, making it a true bolt-on upgrade for riders who want more sound, more style, and more power without the hassle of a full system swap.
