HKS HKSTUDIE Exhaust System for G87 BMW M2

The HKS HKSTUDIE Exhaust System for the G87 BMW M2 is engineered to sharpen performance while preserving everyday comfort. By reducing backpressure, it improves turbo response in the low rpm range and increases torque, making the car feel more eager and responsive off the line and out of corners. During cruising, the exhaust is tuned for a gentle, unobtrusive sound so the driver and passengers remain free from drone or fatigue. But once the throttle is pressed, the system comes alive with a powerful, motorsport-inspired note that matches the dynamic character of the G87 M2.

Unique Tail Tip Design

• The specially designed tail tips pay homage to the legendary BMW 3.0 CSL, featuring thick-walled, slash-cut outlets that emphasize the sculpted edges, with a blasted surface that creates a subtle, satin-like gloss. Integrated sound-deadening inner slits further shape the tone, resulting in a truly one-of-a-kind tail tip design.

Gentle yet Powerful Sound

• The OEM exhaust of the G8X-generation M models already delivers a characteristically sporty M-series tone, but simply replacing the main muffler does not create a dramatic change. The HKSTUDIE exhaust therefore adopts a layout that removes the middle muffler, and its uniquely tuned frequency profile produces a sound that remains gentle in daily driving yet powerful and expressive under load.

Reduced Exhaust Pressure

• An optimized pipe layout and a main muffler designed without internal restrictions reduce exhaust pressure by up to 40% compared with the OEM muffler. This reduction in backpressure improves boost response and high-rpm performance, delivering gains of up to 6.7 horsepower and 25.8 foot pounds of torque.

Features

• Improves power by 6.7hp and 25.8ft/lbs
• Increases sound by 13db compared to OEM system
• 70mm main pipes to quad 60.5mm pipes
