under engine circuit exhaust for Puch mopeds like the Maxi, Newport, Swinger, Dart, Pinto and similar. Also magnum when used with Maxi cylinder. Replace your old clogged, restrictive exhaust with a new one that is designed with performance in mind with no pedal clearance issues!!!
Nice boost over stock in low end, mid range and top end.
