The GasBox Rocket Fin Mufflers

Accurate reproductions of the original Rocket Style mufflers as used by the factory on 1941–1949 Big Twins. A must for correct restaurations.

These parts are not sufficiently homologated for the use within the purview of German road traffic laws. Therefore, use within Germany is only possible on the race-track, for show and exhibition purposes or for restoration of veteran vehicles. Which parts are legal for veteran-restoration, depends on the vehicle's age and must be seen about with the autorities in charge.

Outside of Germany, the homologation and a possible use in road traffic must be seen about with the local authorities in charge.
