LeoVince SITO Complete Exhaust System for Vespa 50 / 90 / 125 ET3 in Steel

The SITO complete exhaust system is a high-quality replacement solution for 4-stroke scooters and is very close in construction to the original exhaust system. This maintains the standard characteristics of the vehicle while benefiting from the proven material quality and workmanship of the SITO product line. The system is ideal as a durable replacement for worn original exhaust systems.

Inside, a so-called "Twin Chamber" double-chamber muffler is used. The inner muffler is constructed separately from the outer structure, achieving effective noise reduction and even exhaust flow. The outer shell made of steel is coated with a high-temperature-resistant electrostatic coating. In combination with phosphating and sandblasting, this creates a particularly resistant surface against heat and weather influences. A plastic heat shield provides additional protection against high temperatures.

Information on Approval for Germany and the European Union

• The BSAU marking (British Standard) represents a purely British type approval and is not a replacement for an EU test mark (E-number) or a general operating permit (ABE).

In Germany, the exhaust therefore has no road approval. Use in public traffic without registration usually leads to the loss of operating permit.

Legalization for road traffic is usually only possible within the framework of a paid individual inspection by a recognized testing center (e.g. TÜV or DEKRA). It is strongly recommended to clarify the possibility of registration in advance.

Installation instructions

The assembly of a LeoVince complete exhaust system is designed in such a way that it can be carried out easily with common tools and some time. The standard mounting points on the scooter are used directly. Additional adjustments are not required.

After loosening the pre-assembly, all components are aligned without tension before clamps and screws are tightened evenly. A final visual inspection and retightening the connections after the first few kilometers ensure a permanently secure fit.
