Stage6 Streetrace Low Mount Exhaust AM6
The Stage6 Streetrace is available here as a low-mount exhaust for 50cc motorcycles with AM6 engine. Designed specifically for 80cc to 90cc setups, this exhaust offers an ideal balance between performance and street legality.
Stage6 Streetrace 80 - 90cc Design
The Stage6 Streetrace is a low-mount exhaust for gear bikes with Minarelli AM6 engines. This exhaust features high-quality craftsmanship and clean welds. The logo is applied directly to the cone for a clean finish, while a protective clear coat effectively helps prevent rust.
The exhaust body comes with a mounting kit for Minarelli AM6.
Note: this is the expansion chamber only; it does NOT include a muffler.
Stage6 Streetrace - Max Performance with E-Approval
This exhaust is optimized for Stage6 70cc - 88cc Big Racing cylinders, providing impressive acceleration and a significantly higher top speed. Surprisingly, the Streetrace 80/90 is actually road-legal / homologated, making it likely the only big-bore exhaust with official approval.
To get the best results, we recommend using a larger carburetor (e.g. PWK 28), a Big Valve reed valve, and a reinforced clutch.
Two different exhaust flanges are included so you can tune your engine's power delivery:
- Short flange = Higher RPM
- Long flange = More torque
Tip: If you remove the restrictors for track use, performance reaches the level of an R/T exhaust.
Which muffler fits the Stage6 Streetrace?
This Stage6 exhaust is supplied without a muffler, giving you the freedom to choose the style and performance level that suits your bike.
For the best setup, we recommend pairing it with a Stage6 muffler that fits your needs:
- For a subtle look and road legality: Stage6 50–80 muffler.
- For a racing look and increased performance: Stage6 R/T 70 muffler.
Important: Even though the Stage6 exhaust is street-legal, this approval becomes void if you use the Stage6 R/T 70cc muffler.

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: Sport
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.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
