ARROW Race-Tech full exhaust system, not homologated, in titanium with stainless steel headers for BMW S / M 1000 R 14-16 | S / M 1000 RR 15-18

ARROW RACE-TECH 71139CKZ full system in titanium with stainless steel headers for BMW S / M 1000 R 14-16 | S / M 1000 RR 15-18

This is the COMPETITION RACE-TECH system with a carbon end cap, which is the titanium model with a titanium link pipe and stainless steel headers.

The Race-Tech silencer was the first exhaust manufactured with a diamond shape, replacing traditional cylindrical or elliptical exhausts. This innovative design allows Arrow to reduce size without compromising internal volume or performance, keeping noise within acceptable limits.

Manufactured with stainless steel internal components and high-tech TIG welds, the Race-Tech optimizes gas flow thanks to strict dimensional control. The rear end cap and gas outlet are designed to minimize turbulence and negative pressure effects.

Available in titanium, carbon fiber, and aluminum, the Race-Tech silencer also has homologated versions for most motorcycles. For some motorcycles, the titanium model includes a carbon fiber end cap.

The Race-Tech exhaust is a masterpiece of engineering, designed to provide exceptional performance and an impressive sound. With a deep and resonant tone, this exhaust adds a sporty touch to the engine sound, enhancing the riding experience.

What material is it made of?

The silencer body is made of titanium. This allows not only for considerably lighter weight (since titanium is one of the lightest metals used in exhaust manufacturing) but also to rapidly dissipate accumulated heat.

The high quality and strength of this material make it difficult to work with, but the result is much more durable, stable products with high heat resistance.

The header is made of high-quality austenitic stainless steel, which offers high corrosion resistance, improved resistance properties at high temperatures, and perfected formability.

The durability of the materials used for its development is track-tested to ensure optimal performance on the road.
