The GasBox WRTT Racer Mufflers

The GasBox WRTT Racer Mufflers

Standard equipment on the Flathead street racing model, the WRTT. Actually not a muffler because it has no restriction whatsoever and is therefore allowed for use on racetracks only.

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 respective assembly group and 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.
