Fabspeed McLaren MP4-12C Sport Catalytic Converters (2011-2014)


Replace the four restrictive factory OEM catalytic converters with two ultra high-performance German HJS 200-cell sport cats for maximum performance and sound, and no check engine light guaranteed. Utilizing our two development McLarens, MP4-12C and a 570S, we've experimented with many designs and were able (after much testing and engineering) to craft the highest quality catted downpipes on the market. We are utilizing bullet proof, high flow 200-cell HJS HD catalysts and incorporate a cast outlet pipe which allows for the smoothest possible flow, the most possible power especially when paired with a tune, and ultimately a superior solution.
