Novarossi 9901 Super Strong Tuned pipe
A lot of buggy racers like to use the Novarossi EFRA 9901 tuned pipe due to his good mileage and power, but with the rough nature of this class it can be difficult for any tuned pipe to stay free from damage. A damaged tuned pipe will hurt your performance and can be costly to repair to replace, so today the Italian company have finished work on a new EFRA 9901 Super Strong tuned pipe, which requires some serious effort to damage it. A very positive side effect from making this pipe is that it vibrates at a different frequency, thus making less noise then the normal 9901. Fully compliant with the latest EFRA regulations for competition use its available trough the usual distribution channels.
