The Polini Original exhaust is a modified standard type exhaust. Polini have designed it to work with both tuned and standard motors and designed it to increase the motors power throughout the rev range whilst retaining good pulling power in the low to mid revs, and all this while remaining outwardly standard looking. Working on the same principals as other exhausts of this type Polini have used an expanding downpipe to boost power and inside the main box Polini have redesigned the baffle plate to keep noise dampened, whilst efficiently allowing the gas to pass through. One thing that make this exhaust stand out above other exhausts of this type is that the Polini Original exhaust is 100% Made in Italy.
