exhaust Tecnigas Silent Pro for Suzuki, Aprilia

High-torque exhaust in a subtle design. Provides considerably more top speed . For those who want a new silencer and want more power, but do not want to ride with a small and particularly sporty sounding exhaust on their scooter. Very good torque curve and excellent performance on 50cc and 70cc sport cylinders. Is suitable for models with Aprilia engine and Suzuki Katana, Zillion and Estilete models. Exhaust system comes with E-certification Note:. If the exhaust E-certified [reduced] is delivered, the installation complies with this condition of the original engine performance and thus can be easily used as original equipment without performance enhancement. This exhaust system is restricted in 2 places: one with two spot welds, fixed directly on the manifold flange and a second small restrictor pipe in the silencer body. Removal will give more horsepower, but invalidate the E-certification
