With a unique bike like the Honda Grom, Two Brothers Racing has designed something special in the S1R exhaust. The innovative carbon fiber S1R exhaust will turn heads with a new design that has been developed to increase the horsepower by 10 percent and reduce weight by 5.5 pounds over the stock exhaust. The S1R 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 will get noticed at the next Honda Grom Prix. Works with stock fender and TBR Fender Eliminator Kit.
The S1R exhaust is a state-of-the-art product from Two Brothers Racing. The system features carbon fiber highlighted by a natural finished Aluminum outlet and stamped spring-mounted inlet for ultimate durability. The Two Brothers S1R exhaust from Two Brothers Racing showcases a race design while increasing all-around performance. All of our carbon parts are made with a high temp aerospace grade epoxy resin. The carbon fabric is made with a 33 million modulus carbon tow then impregnated with the high temperature resin under very tight tolerances.
