Werks Racing’s 2058 Tuned pipe is designed to be a great «all around» pipe. It combines the amazing bottom end power of the 2013 and the smooth feel and great fuel mileage of the 2057! Bottom end will be very strong but slightly less than the 2013. Fuel mileage and top end will be similar to the 2057. With the 2058 you get the best of both worlds!
