A Box Exhaust System for mild/road tuned Vespa largeframe models.

Box style exhaust systems combine an unobtrusive original look with a performance matched to both everyday urban use with longer motorway tours. They possess a sound and price that is also relatively low, especially when compared to fully-blown expansion chamber exhaust types. Since their initial introduction these advantages have convinced an ever increasing number of geared scooter owners for use of these items on their scooters.

Alongside the well-established SIP range of Box exhausts we also have the versions produced by the top two Italian producers of aftermarket tuning components, POLINI and MALOSSI, available in our shop. Both types perform well and also harmonise ideally with a number of motor types. The MALOSSI version has its power band a little higher in the rev range, but compensates by performing over a wider rev range.

Conclusion: Performance enhancing exhaust with an original look.

SIP- TIP: Do not forget to check and adjust both the carburettor jetting and the ignition timing following inclusion of a new exhaust to your motor!
