Are you looking for an exhaust that makes your Piaggio or Gilera drive a little smoother, without you driving around with a loud sports exhaust? The Sito Plus is a logical choice for this. Popular with 2-stroke models such as the Zip, NRG and Runner, and for good reason.
What is the Sito Plus?
Sito makes exhausts that remain close to the original in terms of shape and fit. The Sito Plus has a slightly finer flow than the standard factory exhaust. This makes your engine rev easier and feels freer, especially if your old exhaust has already run out or is slowly clogging up due to carbon deposits.
What do you notice?
The difference is mainly in acceleration and maintaining speed. The sound remains civilized, close to standard. How much you get out of it depends on your setup, the condition of your block and the adjustment.
With or without prop?
Many exhausts have a plug in the bend or muffler part. With prop the passage remains smaller and you stay closer to the original specifications. Without the prop, the engine blows out more freely, which sometimes gives just a little extra acceleration. If you drive on public roads, check whether your setup still falls within the legal requirements.
Fit
The fit depends on engine type, year of manufacture and block variant. Some series have different suspension points or a different bend. Therefore, always check compatibility before ordering. If you are in doubt, please provide your exact details and look at the item number.
Assembly
Preferably assemble when the block is cold. Always use a new exhaust gasket, first place everything loosely in place and align the exhaust neatly before finally tightening. After a short test drive, check the bolts again. You can usually hear a small leak immediately in the sound.
