Introducing the GP-R4 Exhaust: New for 2024 and designed to be an instant classic! This cutting-edge exhaust fuses the bold styling of our GP Cans with the aggressive slash-cut design of the GP-S1, resulting in a standout look and performance that’s sure to impress.

Crafted in the UK with high-grade titanium throughout, the GP-R4 is engineered for maximum durability, lightness, and precision. Its innovative design optimizes gas flow for enhanced performance and a sound that’s both powerful and refined. Available in a rugged Cerakote finish or with an optional conical sleeve (GP-R4C), it’s built to suit a variety of styles while delivering exceptional performance.

Every GP-R4 comes with a removable baffle, offering flexibility in sound output to match your preference. Combining race-inspired aesthetics, premium materials, and impeccable craftsmanship, the GP-R4 is more than just an exhaust—it's the perfect blend of form and function for your ride.
