Bull-X Downpipes 2,75″ Audi S6/RS6, S7/RS7 C7/4G, S8 4H 4.0 TFSI

A downpipe is one of the most popular turbo-engine upgrades. A freer-flowing exhaust side can add a sportier sound while supporting throttle response and power potential. Read more in the Futurez downpipe guide.

This product does not have model-specific ECE approval. It is intended for motorsport and other off-road enthusiast use.

Bull-X Downpipes 2,75″ Audi S6/RS6, S7/RS7 C7/4G, S8 4H 4.0 TFSI offers vehicle-specific bolt-on fitment in place of the original downpipe. Its larger diameter and freer-flowing shape reduce back pressure after the turbocharger. This can sharpen turbo response and reduce exhaust-side thermal load, particularly on tuned engines.

An unapproved catalyst version or catalyst-delete pipe is intended for motorsport and off-road enthusiast use. Do not use an unapproved version on public roads, and always check the current road regulations. On some models, a freer-flowing catalyst may trigger a warning light because the ECU monitors exhaust flow. In these cases, the ECU settings may need adjustment or the downstream oxygen sensor may require a suitable adapter.
