The original style Biturbo, but now with an aluminum silencer. Fits Puch mopeds like the Maxi, Newport, Swinger, Dart, Pinto and similar. Some models may need a new hole drilled for the rear mounting or a small bracket made. Also fits on Magnum when using a Maxi cylinder kit with flat exhaust port instead of the stock magnum angled type.
Nice boost over stock in low end, midrange and top end. Replace your old clogged, restrictive exhaust with a new one that is designed with performance in mind.
