Exhaust Stage6 Streetrace CNC red / black Derbi / Minarelli AM6

Stage6 Streetrace

As the name suggests, the Streetrace series was developed for sporty street use. The Stage6 series includes cylinders and exhausts that deliver relatively high performance, but still function reliably in everyday use.

The Stage6 Streetrace series feature the optimum balance between performance and durability to offer scooter and supermoto riders a high level of riding enjoyment even in everyday use.

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.
