The Polini For Race 4 exhaust has been renewed and the design has been changed to suit the trend of the time. The build and look have changed in style towards the Polini Big Evolution exhaust. The exhaust is based on the data that has been extracted from the Polini Italian Cup race series and therefore both the acceleration and the overall output have been improved, compared to previous versions of the Polini For Race exhaust. The exhaust itself is made up of 7 hand-welded cones, compared to the previous model's 6 cones. The Blackline muffler is built of light metal on which Polini For Race 4 is printed.
Note: The exhaust has been given a thin layer of clear lacquer from the factory, but to ensure that it does not tarnish, we recommend that you regularly maintain the protective layer yourself.
