Bull-X downpipe/ main cat pipes Audi RS3 8P, TTRS 8J quattro 340/360hp (HGDPVAGTTRSHKEM)

BULL-X Exhausts produces downpipes at the highest level. An HG-Motorsport downpipe is a 100% direct replacement for the factory part. Perfect fit and high-quality materials make this item a top product in our range. By optimising the diameter, pipe routing and/or catalytic converter, the load on the turbocharger can be greatly reduced. Lower back pressure and reduced thermal load produce a clear gain in torque and power, an earlier response, and at the same time extended durability.
