SSXAU285 Catalyst Replacement Pipe Set for Audi RS4 B7 4.2 FSI V8

Uncork the legendary 4.2 FSI soundtrack and unleash sharper response on your B7 with this Milltek Sport SSXAU285 front section. This pair of direct-fit catless pipes replaces the restrictive factory converter assemblies, delivering lower restriction, faster throttle pick-up and a harder-edged, motorsport-inspired tone that makes the RS4 feel alive.

We have fitted this exact setup for RS4 owners and the feedback is consistently superb. Expect a stronger mid-range surge, more urgent revs and that addictive V8 bark, especially when combined with a Milltek rear system and the required Stage 2 calibration.
