Take your BMW G2x M340i or M440i to the next level with the Yonristic Catback Exhaust System—engineered to unlock the full power and presence of the B58 inline-six engine. Known for their impeccable balance of luxury, agility, and performance, these models deserve an exhaust that truly brings out their bold character. Yonristic delivers a game-changing upgrade, enhancing both sound and performance.

This system features a 3.5-inch front section and 3-inch piping, designed to maximize airflow and minimize backpressure. The result? Sharper throttle response and noticeable gains in performance. Constructed from T304 stainless steel or ultralight Grade 5 titanium, it dramatically reduces weight—just 30 lbs for titanium and 77 lbs for stainless steel.

Bold quad 4-inch tips complete the look, giving your BMW a sporty edge that matches its dynamic design. Installation is hassle-free, fitting seamlessly with the OEM setup—no modifications required.
