High-torque 2 stroke exhaust by Tecnigas for Kymco SYM Horizontal AC scooters as listed. For those who want a new silencer and want more power but do not want to ride with a small and particularly noisy, sporty sounding exhaust on their scooter then the Tecnigas Silent Pro is a perfect match. Very good torque curve and excellent performance on 50cc and 70cc sport cylinders. Subtle design with low noise level. Exhaust will be supplied restricted and will need to be de-restricted to gain full results, de-restriction may also require further tuning ie. rollers and up jetting of carb. Suitable for use on the following 2 stroke Kymco and Sym models: Kymco Agility 50 RS 2T Naked KE10BB Bet&Win 50 SH10CB / SH10CC Grand Dink 50 G-Dink SF10RA Grand Dink 50 SF10JA Grand Dink 50S SF10JB Heroism 50 Calypso 50 KCZ SB10AC Like 50 2T / Like 50 2T LX KE10AA / KE10AD People 50 BF10AC / BF10AG Super 8 50 2-stroke KF10AA Super 8 50 2-stroke KF10CA Super 9 AC 50 SF10DA / SF10DL / SF10DN Super 9 AC 50 Sports SF10DS Super 9 LC 50 SH10DA / SH10DD / SH10DL Top Boy 50 (COBRA) SF10AF / SF10AG / SF10AK Vitality 50 2-stroke and cross SF10FA / SF10FE YUP 50 SF10EA / SF10EC / SF10EE Yager 50 (Spacer 50) SH10AC / SH10AE SYM Jet 4R 50 2T JD05W Jet 50 01-05 BL05W Jet 50 BasiX 08-12 BL05W Jet 50 EuroX 06-12 BL05W Jet 50 Evo Jet 50 R SportX 07-13 BK05W-6 Jet 50 SR SportX 07-13 BK05W2-6 Jungle 50 GA05W-6 Mask 50 2T 00- Red Devil 50 05-09 Shark RS 50 00-
