Honda Grom exhaust from Two Brothers Racing

With a special bike like the Honda Grom comes an all-new exhaust from Two Brothers Racing. The innovative carbon fibre S1-R exhaust will turn heads with a new design that has been developed to increase horsepower by 10 percent and reduce weight by 5.5 pounds over the stock exhaust.

The S1-R is also fitted with a lightweight spiral wound perforated core and high performance sound absorption packing material. With noticeable horsepower gains, a lighter overall weight, and that striking TBR sound, your Honda Grom is sure to get noticed at the next Honda Grom Prix.
