Tecnigas Silent Pro exhaust Aprilia/Piaggio/Gilera 2-stroke 50cc

Tecnigas has been making exhausts in Europe for a long time, and the quality, light weight and excellent cost-performance is evident. This is the effective and good quality "Silent Pro" model. Use this exhaust on standard 49cc engines or with big bore cylinder kits for a little more performance without making a big fuss about it. Discreet appearance and not too loud! This raises the peak output power and torque for acceleration and hill climbing. Expect more acceleration and unless you have a limited CDI, higher top speed from this exhaust. Carburetor tuning may be required, and lighter weight rollers will need to be fitted (not included). To meet European regulations this exhaust may be fitted with one restrictor - this can be easily removed. To suit the following 2-stroke 50cc models: Aprilia SR50 Motard (Piaggio engine) Gilera Runner/Ice/DNA Piaggio Fly (05->) Piaggio Zip (00->) (NZ market Zip may need the flange bolt holes modified a little by grinding or filing) This exhaust when set up correctly will increase power output from your engine. If required rejetting/roller tuning must be done by a qualified mechanic or experienced person.
