Sport Catalytic Converters

Sport catalytic converters for the McLaren 600LT, replacing the four restrictive factory catalytic converters with two German manufacturer of the high-flow catalytic converters Fabspeed fits in its sport cat products. 200-cell high-flow cats for more power and a fuller exhaust note while staying street legal. Fabspeed pairs the cats with CAD-designed investment-cast inlet and outlet sections for smoother flow, and wraps the assembly in thermal blankets rated to 2200°F, its highest rating, to shield surrounding components from the extra heat. Built from T304L stainless steel with no catalyst-triggered check engine light guaranteed. Fits all 600LT coupes and spiders, plus factory 570S GT4 and 600LT race cars.
