Your exhaust unit is simply equipped with new filter frames with metal grid. To improve support of the filter, you will require additional clamping rails, which are installed at the top. The dimensions for the filter grids are matched to WALTHER systems. Of course, we can on request manufacture grid frames with differing dimensions to suit other systems.
