2023-2025 KAWASAKI ZX-4R/ZX-4RR Stainless Evo Megaphone Full System

After many months of research and development, including in-house design, dyno tuning and track tuning, we can finally announce that we have our full system available for the highly anticipated 2023-2025 Kawasaki ZX-4R/X-4RR! It's time to unleash the potential power from this bike! Check out the Dyno Chart for REAL results on our in-house dyno.

This version is our popular Evolution Megaphone style with your choice of end cap in either stainless, Black Cerakote or Carbon Fiber.

This system is made of thin gauge stainless steel for amazing weight savings (in comparison to stock). We manufacture our full systems out of specialized stainless steel that is super lightweight, as light as titanium (but without the hefty price tag).

This full system weighs approximately 8.4 lbs. (with a stainless/stainless Evolution Megaphone) compared to the stock system that weighs approximately 20 lbs! That's a HUGE weight savings!

Available in a Street version that retains the stock foot peg, or a Race version that includes a CNC laser cut bracket to eliminate the foot peg assembly completely.

If you're running the Graves ZX-4R/RR Oil Cooler Kit, please contact us directly to order that particular system which will give more clearance around the oil cooler and filter.
