| EVO Turbo Double Pipes Technique |
| |
| EVO Turbo Double Pipes Technique is applied to tuning phase of pressure wave for engine exhaust pipe. The pressure wave of main exhaust pipe will be changed by pressure wave of secondary pipe, in order to reduce pressure of exhaust port at Exhaust Valve Open (EVO) period. The discharge efficiency of engine will be better, and the volumetric efficiency is also raised, thus the torque of engine will be increased such as Turbocharger.

| The advantages of EVO Turbo Double Pipes Technique |
- Raised discharge efficiency by tuning pressure wave
- Reduced residual gas in combustion chamber, raise up combustion efficiency
- Improved volumetric efficiency, raise torque and power of engine
- Good accelerating performance for low and medium speed
- Reduced exhaust emission and high fuel economy
- Tuned sound quality of exhaust pipe |
