Bull-X catalyst replacement pipe 2.75″ for Audi RS3 8V, TT RS 8S quattro 367/400 PS

BULL-X Exhausts manufactures downpipes to the highest standard. A downpipe from HG Motorsport can be used as a complete replacement for the standard component. Precise fitment and high-quality materials make this a high-quality product. Optimising the diameter, pipe routing and/or catalytic converter can significantly reduce the load on the turbocharger. Lower back pressure and reduced thermal load provide a noticeable increase in torque and power, earlier response and, at the same time, improved durability.
