Let the B7's V8 be the reason you take the long way home.
The naturally aspirated 4.2 V8 is a huge part of the RS4 B7's appeal. This V2 Milltek cat-back brings its soundtrack into focus with an active H-pipe centre section, separate resonators and valved outlets. The 63.5 mm system is available with four oval finishes for the 2006-2008 Saloon, Avant and Cabriolet.
The H-pipe provides a connection between the two exhaust banks, with the active centre section forming part of this V2 design. Left and right resonators and rear silencers remain in the system, so the V2 upgrade brings the crossover, sound control and rear-end finish together. Keep the traditional polished ovals or choose black or titanium for a different finish.
Each row is one complete system. Select the matching option and part number when ordering.

Audi RS4 B7 4.2 V8 Saloon, Avant and Cabriolet, 2006-2008, V2 exhaust application
This is the V2 system for the 4.2 V8 B7. Allow approximately 2.5-3.5 hours for installation including removal of the original exhaust. A professional installation gives the pipework, tip alignment and hot clearances the attention they need. The system should be checked again after its first heat cycle.
Clean the tailpipes regularly once they are cool, so road dirt and deposits do not become a bigger job later. Use a cleaning product suitable for your chosen tailpipe finish.
For UK customers, prices include VAT, customs and delivery unless checkout states otherwise. For customers outside the UK, local customs and taxes remain your responsibility, and shipping is shown at checkout. If a shipping option is not available, email us and we will prepare a tailored quote.
Many of the products we sell are made to order, imported or custom built, so a lead time may apply. If you need a part urgently, contact us before ordering and we will confirm the expected delivery timeframe and process.
No remap is required for this cat-back change with the rest of the exhaust in its standard configuration. Different requirements can apply if you also change downpipes or catalysts.
The silencer and pipe configuration determine the sound. Pick the finish for the look you want: changing the decorative tips within the same system layout is an appearance choice.
Milltek covers parts containing valves for 2 years or 80,000 km and electronic products for 2 years. Other qualifying parts in this system have lifetime cover. Cover is for the original purchaser and excludes fitting labour and failures caused by misuse or unauthorised modification. Keep your invoice and contact us if you need help with a claim.
Model year, engine, drivetrain, hardware and existing modifications can all change what fits. Check the applications and supplier notes above, or send us your exact vehicle and setup before ordering.
Send us your vehicle, year, current setup and any fitting date, event, trip or deadline before ordering. We will help check fitment, product choice and timing.
