Racing exhaust system is designed for riders who demand the most from their exhaust system in terms of both quality and performance. The header tubes are formed using HYDROFORMING technology! With Akrapovic Racing twin system you will benefit from great power increase and maximum weight savings compared to stock Suzuki exhaust system.
Measurements of the Akrapovic EVOLUTION TWIN system on the SUZUKI GSX-R 1300 HAYABUSA (without noise damper):
The system provides a linear increase throughout the entire range, and the greatest increase is at the very top of the range. We measured 188.5 HP at 10500 rpm on the rear wheel. The max. increased power is 11.5 HP at 6000 rpm.
The torque curve also reflects the exhaust system upgrade. The engine is more responsive in bottom and will provide much more torque through entire rpm range.
