Features:
- 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.
- The OEM exhaust of the G8X generation M produces a sporty sound that is distinctive of the M series. Since replacing onyl the main muffler does not produce a significant change in the sound, the HKSTUDIE exhaust features a layout that deletes the middle muffler. The unique sound tuning based on frequency analysis has achieved gentle yet powerufl sound.
- Although it gives off a powerful sound, it still meets the strict sound regulation in Japan. This products can be used safely for daily use and is compliant with Japan's vehicle inspection regulations.
- Optimized pipe layout and a main muffler without resitrctions reduce exhaust pressure by up to 40% 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 35Nm.
- By manufacturing in-house at our factory in Japan and conducting strict quality control, we are able to offer a 2-year or 30,000km product warranty from the time of purchase.

Increases Output +5kw and Torque +35Nm
Lowering exhaust pressure leads to higher engine power output. The response of the turbo boost is improved in the low rpm range, and torque is increased by up to 15Nm .As for power output, the better exhaust flow leads to more power at higher engine speeds, increasing the power by up to 5kw. All tests at our headquarters were conducted using vehicles in stock condition except for the exhaust system. The difference in power output between OEM and HKSTUDIE exhaust systems will widen further when the ECU is analyzed and tuned to increase power output.
Exhaust Sound Tuning Based On Frequency Analysis
HKSTUDIE produced numerous prototypes of mufflers and conducted a thorough frequency analysis. Especially for the G87 M2, the sound pressure tends to be higher overall due to the shorter exhaust pipe length compared to the M3/M4, and the silencer structure was designed specificalyl for the M2 to muffle the target frequency range in order to keep within the regulation values. General exhaust with internally constructed mufflers will have a marked drone sound, while the HKSTUDIE is able to muffle the low-freuqncy sound just like an OEM exhaust. This drone sound is especially noticeable when cruising at 80 to 100 km/h on highways. In addition, the HKSTUDIE exhaust is tuned to emphasize a mid-freuqncy sound above 200 Hz, which is considered a sporty sound, when the engine is revved to high rpm at full throttle. Thanks to its gentle sound during cruisng, the driver and passengers will not feel any discomfort, and once the driver steps on the gas pedal they will enjoy the powerful sound.
