Exhaust - POLINI Team 4 - Minarelli 50 cc (horizontal) - homologated

The new, homologated POLINI SCOOTER TEAM 4 exhaust systems for Yamaha Minarelli–
horizontal engines were developed using
technology that won races in the Polini Italian Cup.
Specifically, the dimensions of the expansion chamber were adjusted, and
the number of cones was increased to achieve maximum performance
and enhance the racing look.
The latest optimizations are based on the technical specifications of the
Polini Big Evolution mufflers, which are now the top-of-the-line models in the product series.
The muffler is made of black anodized aluminum with a removable back plate to
allow for replacement of the damping material.
Born out of a passion for racing, they are ideally suited for
street use, as they are type-approved: They can therefore be mounted on various 50-cc
scooter models for city driving as well as on tuned engines for track use.
