72211PD Arrow headers BMW R12G/S 2025-2026 titanium racing

The Arrow racing Titanium headers for BMW R12 G/S 2025-2026 and BMW R12 nineT 2024-2026 are designed to fully unleash the potential of BMW’s boxer engine through a decat racing configuration engineered to improve exhaust flow, reduce weight, and deliver an extremely engaging exhaust sound. Developed using race-derived technology, these headers represent one of the most effective upgrades for transforming the character, throttle response, and sound presence of BMW’s modern heritage boxer motorcycles.

Constructed from high-quality Titanium, the Arrow headers significantly improve exhaust gas flow by reducing the back pressure created by the OEM catalytic converter. The result is a freer, more responsive engine with improved performance especially in the mid and high rpm range.

Arrow decat racing headers for BMW boxer models

The racing configuration delivers:

• Smoother power delivery
• Sharper throttle response
• Reduced operating temperatures
• Fuller and more aggressive boxer sound
• Significant weight reduction

Removing the catalytic converter also considerably lightens the motorcycle, improving agility and overall riding feel.

Even deeper BMW boxer sound

The Arrow racing headers generate an extremely deep, metallic, and engaging exhaust note, enhancing the iconic BMW boxer engine pulse with a sportier and more direct tone compared to the stock setup.

Why remove the catalytic converter?

The decat configuration:

• Reduces back pressure
• Improves exhaust gas flow
• Lowers operating temperatures
• Enhances engine responsiveness
• Significantly reduces overall weight
