DetailsExhaust system from the Portuguese manufacturer Tecno. In cooperation with Tecno, this exhaust has been specifically developed for 50/80cc 4-stroke scooters. The exhaust has a CE-mark and can be used legally on public roads. In contrast to the original exhaust, the diameter of the manifold has been visibly increased, which leads to a boost in power. The exhaust is restricted by means of a reduction washer in the manifold, the way you know it from 2-stroke exhausts. In case of 50cc engines, the reduction is, however, negligible. If you are using a bigger cylinder, removing the restrictor does pay off. Remember that the operating licence will expire then.
Don’t forget that with 4-stroke engines, you cannot expect an increase in performance as significant as you know it from 2-stroke tuning. Nevertheless, this exhaust is a good alternative to the very low-quality original exhausts made in China. This is so far the only exhaust system for this vehicle with E-mark.
