MVT S-Race SP3 exhaust
After the success of the SP2 for 50cc cylinders, MVT is following up with the new SP3: a racing exhaust designed specifically for 70 to 80cc engines. The MVT SP3 S-Race exhaust system is part of the S-Race series, perfectly matched to the 70 - 80cc S-Race cylinders from MVT.
Design and performance MVT S-Race 70 - 80cc
The carefully segment-welded exhaust is designed for high port timings (180° - 190°) and delivers a wide power band and strong performance, for improved acceleration and higher top speeds.
The adjustable flange (25mm) allows for optimal cylinder to exhaust alignment and gives a bit of room for fine-tuning since you can slightly shorten or lengthen the exhaust tract.
The welded exhaust comes with a stylish red anodized aluminium silencer.

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.
