At DMG Motorsports, we present the Yoshimura Street R-77 Slip-On Exhaust SS-CF-CF Dual (Part #1412202) — a race-bred dual muffler system built for riders who demand serious performance without sacrificing street-legal reliability. Developed using feedback straight from Yoshimura's own road racing program, the R-77 combines a distinctive trapezoidal profile with premium stainless steel and carbon fiber construction to deliver a lighter, better-flowing exhaust that still looks right at home on the street. This dual slip-on configuration is designed to fit the Kawasaki Z1000, giving your bike an aggressive stance and a deep, race-inspired exhaust note.

Engineered rather than just styled, the trapezoid-shaped sleeve maximizes internal packing volume for improved flow, while the straight, single-core baffle keeps performance consistent and the sound refined. A MIG-welded front cap paired with a riveted end cap using high-end 304-L polished stainless steel hardware ensures the kind of hand-built durability Yoshimura is known for. A removable low-volume sound insert also gives riders the flexibility to fine-tune the exhaust note to their preference.
