This is the list provided by the manufacturer for item 0246. If you have any doubts, send us the chassis number of your moped and we will verify the correct code for you.

Who it is perfect for

This is the exhaust for those keeping a Si or Boss alive and actually using it. On these mopeds, the stock exhaust is almost always the first part to go: it rusts from the inside, develops holes in the belly, and eventually loses power and becomes noisy. This unit replaces it while maintaining the original round shape, and since it is type-approved, the vehicle remains road-legal without having to search for a thirty-year-old used replacement.

Frequently asked questions

On which mopeds does the Sito 0246 exhaust fit?
It fits Piaggio Si, KS, FL2, and Boss 50 two-stroke mopeds, in the round-shaped exhaust version: this is the application group declared by LeoVince for this item. If the muffler mounted on your vehicle is not round-shaped, this is not the correct code.

Is it type-approved? Can I use it on the road?
Yes: LeoVince declares it a type-approved exhaust device according to EC Directive 97/24 Chapter 9. However, pay attention to a detail the manufacturer emphasizes: the approval is valid only for the Types listed in the ePass attached to the manual, so compare that code with the Type on your registration document.

Is the manifold included or must it be purchased separately?
It is included. The manufacturer describes the kit as complete with a manifold and specifies that it requires no additional parts for installation: the box contains the muffler, its manifold, and the heat shield. You only need to provide gaskets and hardware, which are not part of the kit.

What does "round shape" mean?
Two muffler shapes existed for these Piaggio mopeds, and the replacements are not interchangeable. This item is the round version: look at the muffler mounted on your vehicle and compare the profile with the photos before ordering, as this is the detail that distinguishes this code from others in the same family.

Does it increase performance compared to the original exhaust?
This is a Sito line replacement, designed to replace the stock exhaust while keeping the vehicle type-approved. LeoVince does not claim power or torque increases for this item, and we do not report any: anyone looking for a performance exhaust should look at a product from the sports range, not this one.

How can I be sure it is the right one for my moped?
Check the model and muffler shape, then compare the Type on your registration document with the product's ePass. If you still have doubts, write to us with your chassis number: we will check the LeoVince catalog and confirm if this is the exhaust intended for your vehicle.
