Bull-X Downpipes 2.75″ Audi S6/RS6, S7/RS7 C7/4G, S8 4H 4.0 TFSI

These downpipes from Bull-X can be replaced 1:1 against the original parts. Perfect fit and high-quality materials make these items a top product in our range. By optimizing the diameter, the piping and catalysts, the turbochargers are greatly relieved.
The lower dynamic pressure generates a significant increase in torque, performance and early response, while at the same time prolonging the thermal release life.

Attention:
1. The OEM downpipes are crossed, so the lambda sensors must be installed crosswise after the installation of these downpipes (the probe from the left to the right downpipe and the probe from the right to the left downpipe)
2. Not suitable for installed Akrapovic system, as other presilencers are installed here!
