High-torque exhaust in a subtle design. Provides considerably more top speed. All need a new exhaust 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. Fits on all air and water-cooled 2-stroke engines, also fits Piaggio Purejet [injection] engines.
