Exhaust Stage6 R/T FL 70cc
Description
Stage6 R/T FL70 Exhaust – High-End Racing Exhaust for FL Crankcases
Stage6 R/T specifically developed the Stage6 R/T FL exhaust for maximum performance on FL / flange mount cylinders. In addition to being the ideal match for the Stage6 R/T FL 70cc cylinder kit, it is also suitable for other high-end racing flange mount cylinders with comparable power potential.
Stage6 R/T 70FL - Maximum Performance
The optimized exhaust geometry is designed for a very high rpm range from 14,000 to 15,500 rpm. It ensures high cylinder filling and delivers powerful power delivery across the entire usable powerband.
The exhaust offers high peak power paired with a wide, usable powerband. Instead of restricting the engine to an extremely narrow rpm window, the RT70 FL supports high peak power with a wide, usable powerband, unleashing its full potential right where high-end racing engines need it.
The precisely tuned resonance characteristics deliver strong performance while making engine and CVT tuning much easier.
Stage6 R/T 70 FL - Thoughtful Design & High-Quality Craftsmanship
The exhaust features a curved racing-style mid-pipe and is designed for installation on tuning crankcases with flanged mount patterns (Malossi C-One / RC-One, Polini P.R.E., 2Fast Passion, TPR Factory, etc.).
This classic racing exhaust is carefully hand-welded from thin sheet steel. It comes in an unpainted racing finish and is fitted with a high-quality carbon silencer.
Tip: To prevent premature rusting, regular application of grease spray is recommended.
Note: Delivered without a flange, as it is already included with the Stage6 R/T FL 70 cylinder kit; for other cylinders, a matching flange may be required.

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: High End 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.
High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.
Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.
