A one-of-a-kind tail tip design
A specially designed tail tips paid homage to the legendary “BMW 3.0 CSL“. It has a thick-walled slash-cut tail tips, emphasizing the texture of the edges, and the surface is blasted to express a dull glossy finish. Features a sound deadening inner slits to create a one-of-a-kind tail tip design.

Gentle yet powerful sound
The OEM exhaust of the G8X generation M produces a sporty sound that is distinctive of the M series. Since replacing only the main muffler does not produce a significant change in sound, the HKSTUDIE exhaust features a layout that deletes the middle muffler. The unique sound tuning based on frequency analysis has achieved gentle yet powerful sound.

Reduce exhaust pressure by up to 35％
Optimized pipe layout and a main muffler without restrictions reduce exhaust pressure by up to 35% compared to the OEM muffler. This results in increased boost responsiveness and higher output at high RPM range, and increases power output by up to 5kw and torque by up to 15Nm.
