Who it is perfect for

It is the ideal muffler for those who take their T5 to the track or to rallies closed to traffic, and for those who are rebuilding a T5 engine and want a sporty Sito Plus exhaust instead of the original one that has rusted through. It is not the right part for a street-legal, road-going T5: for that, you need a homologated exhaust, which this is not.

Frequently asked questions

Which Vespa does the Sito Plus 0243 muffler fit?
It fits the Vespa 125 T5, the 125 two-stroke, five-transfer port model with frame prefix VNX5T. This exhaust is dedicated to that frame: it is not interchangeable with the PX exhaust or exhausts for Vespas of other engine sizes. Check the prefix on your registration document before ordering.

Can I use it on the road?
No. This item is non-homologated and is intended for use in closed-circuit competitions. For public roads, you need a homologated exhaust: if your T5 is road-registered and driven, this muffler is not the correct replacement part.

Is the manifold included or must it be bought separately?
It is included: this is a complete system, meaning silencer plus manifold in a single replacement unit, which replaces the entire stock exhaust. Gaskets and hardware are not included in the package and must be obtained separately before installation.

How much power gain can I expect compared to the original exhaust?
We do not provide figures: LeoVince does not claim power or torque increases for this item. The difference compared to the original lies in the fact that it belongs to the sporty Sito Plus range and is not homologated; the performance on your T5 depends on how the engine is tuned.

What material is it made of and how does it perform over time?
It is made of steel with a black paint finish. Like all steel exhausts for these vehicles, it is susceptible to humidity when not in use: if the Vespa remains in the garage for a long time, it is advisable to keep it dry and occasionally check the attachment points and the bend area, where rust tends to start first.

How can I be sure it is the right one for my Vespa?
Compare the frame prefix on your registration document with the VNX5T in the table. If it does not match, or if the engine has been modified from the original, write to us with the full prefix: we will check the LeoVince catalog and confirm whether this is the exhaust intended for your vehicle.
