High torque exhaust in a rather inconspicuous look. Brings significantly more final speed. For all those who need a new exhaust and want more power, but do not want to ride a racing bag on their scooter. Very good torque profile and very good performance on 50 and 70 sports cylinders. Fits all new PGO models. The system has an E-mark. Performance note: If the exhaust is supplied with E-mark [throttled], the system corresponds to the original engine power in this condition and can therefore be easily used as an original spare part without increasing performance. In this system, the throttle is located as a welded reducing sleeve in the exhaust manifold. After removal, the engine power increases significantly, but at the same time the general operating permit (ABE) expires.
