Technical improvements and further development for racing
The Polini FOR RACE 5 exhaust series takes a new, decisive step forward.
With the FOR RACE 5, Polini introduces significant improvements to the entire exhaust series,
which are the result of continuous development, experience on the race track and real racing data.
.
The most significant improvement concerns the course of the exhaust manifold, which has been completely
redesigned from the cylinder outlet to the first cone of the expansion chamber.
This new design optimizes the exhaust flow and significantly improves engine response,
mid-range torque and acceleration.
The new expansion geometry, which is increasingly inspired by Big Evolution concepts,
is the result of telemetry analysis and data collected during Polini Italian Cup competitions on all race tracks.
The result is an even more powerful, responsive and rideable exhaust that can improve any race set-up.
The silencer is made from parts with different dimensions, entirely welded by hand,
which confirms Polini's high level of craftsmanship.
The black silencer, whose mounting system and end caps have been revised,
is made from a lightweight alloy with laser engraving and a straight inner pipe.
