Description
Milltek SSXAU870 Large-bore Downpipes and Cat-bypass Pipes for the Audi RS6 / RS7 (C8) and S8 (D5)
The Milltek SSXAU870 is a set of 80mm large-bore downpipes with cat-bypass pipes for the 4.0 V8 bi-turbo Audi RS6 and RS7 (C8) and the S8 (D5). Built from stainless steel with heat-wrapped de-cat construction, it dramatically frees up the twin-turbo V8 for stronger flow and a harder-edged, more aggressive note. This is a race-oriented, non-E-marked component intended for track and off-road use. It ships to Dubai, across India and worldwide.
