These Bull-X downpipes are a direct replacement for the original components. Precise fitment and high-quality materials make them a top-quality product.<\/p>\n<p>The optimised diameter, pipe routing and catalytic converters significantly reduce the load on the turbochargers. Lower back pressure provides a noticeable increase in torque and power, together with earlier engine response.
