BULL-X Exhausts produces downpipes to the highest standards. An HG Motorsport downpipe can replace the standard component completely. Perfect fitment and high-quality materials make this a top-quality product. Optimising the diameter, pipe routing and/or catalytic converter significantly reduces the load on the turbocharger. Lower back pressure and reduced thermal load provide noticeably more torque and power, earlier response and increased durability at the same time.
