Description

Doppler Sport Exhaust S3R.

The expansion chamber is made of sheet metal (rolled and welded) and coated, the silencer is made of aluminium, available in black or white.

It is street-legal, yet very powerful throughout the entire rpm range. It can be combined with almost all cylinders on the market and is ideally suited for original or 50cc and even 70cc sports kits (even Mid Race!).

To unlock its full potential, you should combine it with a 17.5mm carburetor (in line with the type of cylinder that's used) and a racing variator and clutch.

This is the version with black silencer!

For Minarelli vertical

Notes and Safety

Exhaust scooter, moped, motorcycle

The exhaust has a major influence on the performance of scooters and mopeds. By replacing the original with a tuning exhaust, you can improve the gas flow and increase the engine power.

exhaust parts

  • The headpipe or header is the connection between cylinder and exhaust, and an exhaust gasket provides the necessary seal. In street-legal systems, the headpipe is equipped with a legally required restriction. Some people remove this restrictor to increase power.
  • The actual exhaust body or expansion chamber is connected to the header pipe. In a classic 2-stroke expansion chamber type exhaust, gas pressure waves are used to improve engine performance.
  • At the end there us the silencer or muffler that discharges the exhaust gases and, with the help of damping wool, also reduces the noise generated by the vehicle.

Replacing the exhaust

For 2-stroke engines, various settings and components usually need to be adjusted when the original exhaust is replaced with a tuning version. These changes include:

Tuning Level: Racing

We categorize our products into different performance levels  Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.

Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
