Arrow Pista Slip-On Silencer Titanium BMW S1000RR K67 (2019-2026) 71506PT

E-number approved and engineered for real-world roads as well as the circuit, the Arrow Pista 71506PT slip-on silencer brings race-derived titanium construction to the BMW S1000RR K67 without surrendering street legality. Weighing just 2.30 kg, it delivers a measurable reduction over the factory unit while the carbon end cap and stainless steel internals set the tone for a machine that looks as serious as it performs.

Key Features

• E-number road-type approval: fully legal for public roads straight out of the box, with no registration complications.
• Titanium canister construction offers exceptional heat resistance, corrosion immunity and a weight of only 2.30 kg for improved handling dynamics.
• Carbon end cap combines structural rigidity with the premium finish expected of a competition-grade silencer.
• Stainless steel internals maximise longevity and resist the thermal cycling of high-revving inline-four use.
• Removable db-killer reduces sound output for street riding and can be extracted in moments for track days.
• Plug-and-play fitment to the OEM header means no cutting or welding — installation is straightforward for any competent home mechanic.

Approval, Compliance and Road Use

Arrow has engineered the 71506PT with an E-number type approval, meaning it satisfies European noise and emissions regulations as a slip-on replacement. The included db-killer keeps the system within road-legal limits, while its tool-free removal transforms the sound character for unrestricted track sessions. Riders who want full compliance need only leave the db-killer in place — there is nothing further to modify or declare.

Materials and Construction

The titanium canister is the heart of the Pista series. The alloy is chosen for its extraordinary strength-to-weight ratio, its ability to withstand the sustained thermal loads of a 210 hp inline-four, and the distinctive natural patina it develops with use. At 250 mm in total length with a 60 mm inlet and 60 mm outlet, the silencer integrates cleanly with the K67 chassis without fouling bodywork or the rear wheel.

Internally, stainless steel baffling and packing support durability over tens of thousands of kilometres, resisting moisture ingress and the vibration inherent in high-revving track-oriented engines. The carbon end cap is not a cosmetic afterthought — it adds stiffness to the outlet face and saves additional grams versus a metal equivalent.

Performance and Tuning

As a direct OEM-inlet slip-on, the 71506PT delivers a more liberated exhaust note and marginal mid-to-top end gains without any additional modification. For riders seeking the full performance potential of the BMW S1000RR K67, Arrow recommends pairing the 71506PT with a compatible Arrow header to form a complete exhaust system, unlocking improved throttle response and power delivery across the rev range. A custom ECU remap or Arrow-specific mapping is recommended to fully exploit the freer-flowing exhaust and ensure optimal fuelling at all throttle positions.

Fitment and Compatibility

The Arrow Pista 71506PT is designed and type-approved specifically for the following motorcycle:

• BMW S1000RR K67 — model years 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026

The silencer connects directly to the factory mid-pipe or, for maximum system performance, to a compatible Arrow header. No additional brackets or adapters are required for standard fitment on the above models.
