The Arrow Pro-Race Low complete exhaust system 71204CP is one of the most practical full-system upgrades available for the BMW M1000RR K66. Weighing just 3.62 kg and engineered to deliver measurable gains in throttle response and power delivery, it is the kind of bolt-on investment that rewards both dedicated track-day riders and serious club racers who want more from every session without compromising reliability.
Key Features
- Stainless steel headers for outstanding heat resistance, rigidity and long service life across repeated high-temperature track cycles.
- Titanium silencer, end caps and internals for exceptional heat dissipation and an overall system weight of just 3.62 kg.
- Removable dB-killer included — reduce noise levels for noise-sensitive venues, then pull it out for unrestricted performance when conditions allow.
- 250 mm silencer length with a 68 mm outlet connection diameter, engineered for a precise factory-quality fitment.
- Optimised exhaust gas flow developed specifically for the M1000RR K66 platform, improving throttle response and peak power under racing conditions.
- Straightforward installation designed to integrate cleanly with the existing M1000RR K66 chassis and ancillaries.
Build Quality and Materials
Arrow has paired two complementary materials to give this system the best of both worlds. The headers are fabricated from high-grade stainless steel — a choice that prioritises durability and dimensional stability under the sustained thermal loads generated by the S1000RR-derived four-cylinder engine. The silencer, end caps and all internal components are manufactured in titanium, which keeps weight to a minimum while handling heat more effectively than steel equivalents. The result is a system that feels purposeful and premium without unnecessary mass.
Track-Day Practicality
Everyday track-day usability has been central to the design of the 71204CP. The included dB-killer fits securely and removes in seconds, meaning you can comply with circuit noise limits without carrying additional hardware. A custom ECU mapping is strongly recommended to unlock the full performance benefit of this system and achieve the sharpest possible throttle response across the rev range.
Important Notice
Race-use only — this complete exhaust system carries no road-use type approval. It is intended exclusively for closed-circuit competition and track-day use. Ensure compliance with your venue's noise regulations when the dB-killer is removed.
