Rear diffuser with duplex suitable for MX-5 ND. Available in gloss black as well as matt. Also suitable for the SPS Motorsport exhaust system with duplex at the ND as well as for the rear silencer with duplex for the ND. The diffuser is simply glued over the original rear attachment. Before that, the new cutout for the tip has to be cut into the original rear bumper. We recommend installing a screw at the corners of the rear bumper to ensure additional safety.
