Puch exhausts and accessories

For a standard 50cc setup, a 22mm exhaust bend is recommended. If you have a tuned 50cc or a larger cylinder (65cc, 70cc, or 74cc), a 28mm exhaust provides the required gas flow for better performance.

The flange is where the exhaust mounts to the cylinder. Standard Puch cylinders have a straight port pointing straight down. Many aftermarket tuning cylinders have an angled port. You must buy an exhaust that matches your cylinder's port design, or it will not mount correctly.

Yes, usually. A performance exhaust increases airflow through the engine. To compensate and prevent the engine from running lean, you typically need to increase your main jet size by a few steps.

Expansion chamber exhausts are generally louder than the original standard cigar models. However, the exact sound level depends heavily on the type of silencer and the condition of the damping wool inside it.

Not all performance exhausts are compatible with original pedals; some wide expansion chambers will get in the way. We usually mention in the product description whether an exhaust is suitable for mopeds with pedals or if it requires a kickstart setup.
