This racing line exhaust system for the ZX-4R and ZX-25R is the ideal upgrade for riders who seek exceptional performance and value. As a complete step forward in tuning, it delivers an impressive balance of power, lightweight construction, and dynamic sound—all crafted with precision and racing spirit in mind.

Engineered for those who demand more from their ride, this system is significantly lighter than the stock exhaust and offers enhanced engine performance along with a bold, race-inspired tone. Premium materials like carbon fibre for the muffler’s outer sleeve not only reduce weight but also add a sleek, high-performance aesthetic.

Designed with versatility in mind, this exhaust system is also fully compatible with the ZX-25RR model.
