At DMG Motorsports, we present the Yoshimura Exhaust Street AT2 SS-SS-CF (14720BP520) — a stainless steel slip-on muffler with a carbon fiber end cap, purpose-built for the Kawasaki ZX-4RR platform. Yoshimura developed the AT2 muffler specifically to unlock the potential of this high-revving inline-four, and the results speak for themselves. Riders can expect a measurable bump in horsepower and torque along with a noticeable reduction in weight compared to the stock exhaust, all wrapped in Yoshimura's iconic Works Finish and matte carbon fiber styling. As a true bolt-on/slip-on unit, it installs without tampering with your bike's emissions system, making it a straightforward upgrade for street riders who want race-inspired sound, look, and performance without the hassle. Backed by Yoshimura's decades of exhaust engineering experience and proudly made in the USA, this AT2 slip-on delivers the aggressive tone, weight savings, and show-stopping finish that Yoshimura is famous for.
