Polini sport exhaust for classic moped
Racing exhausts for Peugeot 103 have become rare, so we're happy to make the Polini Sport Exhaust Peugeot 103 available to you, as always for a good price.
The expansion chamber is made of 2 steel half-pipes (welded together) with weather-resistant coating, coming with a racing silencer (attached with screws).
It is not street-legal and suitable for Polini's "Sport" cylinders for Peugeot 103, and is also compatible with their 50cc Aluminium "W" and 70cc Aluminium or Cast Iron cylinders.
It is quite powerful at mid and high rpm range and will give your Peugeot 103 a unique "vintage" look. This exhaust is not sitting on a flange, but directly attached to the engine and is accordingly moving with it (just like the 90ies' "snail" exhausts.)
Excellent choice if you're looking for a powerful exhaust with an original, vintage look.

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
As a general rule, please check if the exhausts fits BEFORE REMOVING THE RESTRICTOR, otherwise the exhaust cannot be returned.
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:
- Adjusting the carburetor by replacing the main jet.
- Upgrading the clutch or replacing the clutch springs.
- For scooters, it may be necessary to reduce the weight of the variator weights.
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.
