Designed for both street and track use, the Alien Head 2 is one of Brock's best-selling performance exhaust systems. The system features a 14-inch show-polished megaphone muffler with a 2.25-inch permanent baffle, providing outstanding exhaust flow while maintaining a powerful, race-inspired exhaust note. Its high-flow flange kit and larger outlet maximize horsepower and torque on both stock and modified Hayabusa engines. Constructed from aerospace-grade ultra-lightweight stainless steel, the Alien Head 2 offers excellent durability, corrosion resistance, and significant weight reduction compared to the OEM exhaust, resulting in improved acceleration, handling, and overall performance.

The spacer kit is not required for Gen 2 Hayabusa models. Riders can also install an optional 2.25-inch noise reduction insert (sold separately) for quieter operation. A C44 Eliminator Plug is available separately to prevent the FI warning light after removing the factory O₂ sensor.
