Which RS6 C8 listing fits your car?
The C8 range is split in two. Cars with a petrol particulate filter, which includes UK and European RS6s from 2019, are listed as OPF/GPF. US and rest-of-world cars without the filter are listed as Non-OPF/GPF USA/ROW. Check which you have first, then order from the matching group.
OPF/GPF cars have the widest choice: a filter-back system in Titanium Signature Series form or for the Performance Edition, a front pipe-back system, front silencers and a Titanium Signature Series axle-back upgrade kit. Non-OPF cars have a cat-back system, which replaces everything behind the catalysts.
RS6 C7 4.0 TFSI and earlier cars
The 2013 to 2018 C7 can take a cat-back or a full system. Many RS6 listings come resonated, non-resonated or, on some, Road+ part resonated: resonated keeps the cabin calmer on long motorway runs, non-resonated is louder. Oval tips are offered in polished, Cerakote black, black, titanium and carbon fibre, and a separate set of C7 tips suits owners who only want to change the look. Our tip styles page compares the finishes.
Older cars are not forgotten: the C5 Saloon and Avant and the C6 5.0 V10 each have a cat-back system.
Downpipes and cats for the RS6 C7 and C8
Sports cat downpipes keep a catalyst and are listed for the C7, the C8 OPF/GPF and the non-OPF C8. Downpipes with cat bypass, listed for the same three, do not: they are for off-road and competition use only and will fail an MOT emissions test. Many are offered to suit either the standard exhaust or a Milltek cat-back, and an ECU remap is usually needed. Related parts are in manifolds, de-cats and sports cats.
RS6 valve control, trims and suspension
Active Valve Control is listed separately for the C7 and the C8 OPF/GPF, and you will find it with our other electronics. The C8 OPF/GPF also has carbon fibre trims and rear trim finisher plates, and the C7 has an Active Suspension Control unit. The RS7 uses the same 4.0 V8 and has a closely matched range.
