Primary Sport Cat Downpipes
Primary Sport Cat Downpipes for the Range Rover L405 and Sport (2013-2020), replacing the four restrictive factory catalytic converters with German-imported Fabspeed's German catalytic converter supplier; HJS cores flow close to a straight pipe while still scrubbing emissions. 200-cell cats. Built from 14-16ga mandrel-bent T304L stainless steel, they save 7 lb over the factory downpipes and add an aggressive rumble under acceleration with no droning off-throttle. Paired with Fabspeed's XperTune Performance Software, peak gains reach 50.39 whp and 57.49 ft-lb of torque. Simple bolt-on swap for the stock downpipes, with no catalyst-related check engine light guaranteed.
