Show original supplier description
The M4 Exhaust Full System is designed for the Kawasaki Ninja ZX-4RR, specifically for the 2023-2025 model years. This full system features a Street Slayer X96 Carbon Fiber Canister, offering a significant weight reduction of 8.8 lbs compared to the original stock exhaust. The system is equipped with an M18 O2 bung, making it compatible with aftermarket fuel controllers for optimized performance tuning. Additionally, it is compatible with the Stage 1 Q8 Quiet Insert, which is sold separately, allowing users to adjust sound levels. While M4 Exhaust generally aims for direct-fit installations, it is always recommended to consult the specific fitment guide for your vehicle.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
