The Audi RS6 GT super estate is already a machine that leaves very little to be desired. As one of the most exclusive C8-generation RS6 models ever produced, this limited-edition powerhouse combines motorsport-inspired aerodynamics with track-honed chassis upgrades, setting it apart from even the mighty RS6 Performance. With just 660 cars worldwide, the RS6 GT sits at the pinnacle of Audi Sport engineering — aggressive, focused, and dripping with rarity.

But for Automotive Addiction boss Dhyllan, as special as the Audi RS6 GT is in standard form, there was one area that begged for enhancement: the exhaust note. A car this hardcore deserves a soundtrack to match its visual drama and dynamic capabilities. Enter Akrapovic — the world leader in high-performance exhaust systems — and their RS6 GT titanium exhaust system. Designed specifically for the C8-generation RS6 Avant, and priced at just over £10,000, it’s as serious as the car it was built for.

When it comes to Audi’s iconic RS models, few companies possess as much in-depth knowledge and expertise as Automotive Addiction. Having sold over 700 highly specified RS models over the years, as well as being moderators on the Audi RS OC Facebook group and the owners of the Audi RS3 8Y and Audi RS6 GT Owners Club Facebook groups, there’s very little we don’t know about the Ingolstadt brand’s legendary machines.

But we don’t just sell them. As passionate enthusiasts ourselves, we own them and modify them too, turning both our customers and our own automotive dreams into reality, which is exactly what we are doing by adding an uprated exhaust system to our ultra rare C8-generation RS6 GT.

Why the RS6 GT is So Special

Before diving into the titanium exhaust system transformation, it’s worth revisiting why the Audi RS6 GT is so significant. Inspired by the legendary IMSA GTO race cars of the late 1980s, the GT is more than just a styling exercise. Audi Sport stripped weight, sharpened handling, and added aerodynamic trickery such as a huge adjustable rear wing, front wing vents, and aggressive carbon details.

The twin-turbocharged 4.0-litre V8 remains ferociously capable, with over 600 horsepower on tap, but it’s the car’s sharper character and limited production run that elevate it into instant collector’s item territory. This is Audi’s most focused RS6 yet — and as Dhyllan explained, “A car this hardcore deserves an exhaust note that lives up to the way it looks and drives.”

Why Akrapovič?

When it came to choosing the right exhaust, there was really only one name at the top of the list. Akrapovic has built its reputation through decades of motorsport success and by supplying factory racing teams with some of the most advanced exhaust technology on the planet. Bought from tuning specialists Peron Automotive, the Akrapovic titanium exhaust system offered the perfect blend of sound, performance, and engineering pedigree for the Audi RS6 GT super estate.

Manufactured from high-grade titanium, the Evolution Line system is a masterpiece of design and execution. It features one central and two side mufflers, linked by titanium collectors and freer-flowing stainless-steel link pipes that are larger in diameter than stock. Akrapovic even went as far as developing custom-made flex tubes, fully insulated where they attach to the downpipes, ensuring durability and precision fitment.

Compared to the stock system, the Akrapovic titanium exhaust system is not only lighter with a more consistent diameter bore and smoother bends to optimise gas flow, but it also looks much better too, its simple uncluttered lines and stunning titanium finish producing a system of unrivalled beauty – even if most people won’t even see it!

Control comes via three valves — one on each side muffler (as with the OEM system), plus a third inside Akrapovič’s complex active X-connection. All of these housings are cast in Akrapovic’s in-house foundry, underlining just how bespoke this system really is. The result is not just a louder exhaust, but one that is acoustically tuned to perfection across the entire rev range, and our Audi RS6 GT is the very first in the UK to receive this stunning system.

Tailpipes with a Difference

The finishing touch is a set of unique carbon-fibre/titanium tailpipes. Unlike anything Akrapovic has produced before, they combine a handmade carbon-fibre sleeve with a sandblasted, coated titanium inner section. The result is a muscular, motorsport-inspired look that perfectly complements the Audi super estate’s widened arches and aggressive aero. For even more drama, Akrapovic also offers a handmade carbon diffuser, available in either matte or gloss finish.

The Installation

Even though the titanium exhaust system comes with all necessary gaskets, fixings, wiring, and detailed instructions for installation, fitting the Audi RS6 GT exhaust to our car wasn’t without its challenges. The downpipe bolts and valve wiring are notoriously awkward to reach on the C8-generation RS6 platform, and with such an expensive system, precision is everything. Before installation, the entire setup was painstakingly ceramic coated to protect it from the elements and retain its flawless finish for years to come.

Once installed, the difference was immediate. Even in Comfort mode with the valves closed, the note is noticeably deeper and more purposeful than stock. Switch into Dynamic mode or use the handheld Akrapovic controller to fully open the valves, and the RS6 GT comes alive. The tone sharpens, volume increases significantly, and every downshift is punctuated by a crisp bark and overrun crackle. It’s everything Dhyllan wanted — an exhaust note that matches the GT’s extreme presence.

Sound and Performance

The real genius of the Akrapovic Audi RS6 GT exhaust is its balance. Despite the more aggressive tone, there’s no unwanted drone at motorway speeds. You can commute in Comfort mode without disturbing the neighbours, then unleash the full V8 soundtrack when the mood strikes.

Akrapovič also backs up the drama with measurable performance gains. On their in-house dyno, the Evolution Line (Titanium) showed a 15.7bhp increase at 6,150 rpm and a torque gain of 17.9 Nm at the same point, compared to Audi’s stock Sport exhaust. Perhaps even more impressive is the 10.4 kg weight saving — more than 20% lighter than the factory setup. In a car like the C8-generation RS6 GT, every kilo counts.

The Result

For Dhyllan and the Automotive Addiction team, this titanium exhaust upgrade was about unlocking the full character of the Audi RS6 GT. The Audi RS6 C8 exhaust system from Akrapovic amplifies everything that makes this car special — rarity, aggression, performance, and presence. It’s an investment in both sound and performance, a system as meticulously engineered as the car itself.

In Comfort mode, it remains civilised enough for long journeys or daily use. But open the valves with the press of a button, and the GT transforms into something feral, snarling with motorsport DNA. It’s a true Jekyll-and-Hyde experience that elevates the already special Audi RS6 GT into a league of its own.

When it comes to Audi’s iconic RS models, few companies can claim to have as much in-depth knowledge and expertise as Automotive Addiction. Having sold over 700 highly specified RS3s over the years, as well as being moderators on the Audi RS OC Facebook group and the owners of the Audi RS3 8Y and Audi RS6 GT Owners Club Facebook groups, there’s very little we don’t know about the Ingolstadt brand’s storming hot hatches.

But it’s not just the hatchbacks that we specialise in, as our passion also extends to the firm’s supercars and super saloons too, being the proud owners of both an R8 V10 Performance Parts Edition (one of only 44 worldwide and just 5 in the UK in right hand drive) and two – yes two! – RS6 GTs (one of only 660 worldwide and just 60 in the UK) where one of these uber limited wonder wagons is available for purchase while the other is remaining at Automotive Addiction HQ to be used as an ongoing project!

These ultra exclusive, limited edition models are not the kind of car you can simply buy anywhere, as their extreme rarity means only a handful of the UK’s most respected dealers and enthusiasts get offered the chance to buy one.

Launched in February 2024, with cars having only just been released to those exclusive outlets and individuals in early 2025, the RS6 GT is the latest, and possibly greatest, Audi model to enter the Automotive Addiction preparation booths.

Priced at an eye-watering £178,000 it is the most expensive Audi model ever released. Built as a homage to Audi’s American IMSA Sportscar Championship race car of the 1990s, it’s wild red, white and black colour scheme and brawnier bumpers may look just like  a cosmetic makeover, but the gamut of the GT’s bespoke parts and abilities are much more than just skin deep.

To see exactly how the range topping GT compares against the next best thing, we put it up against its slightly less exotic stablemate, the RS6 Carbon Vorsprung. But being Automotive Addiction, even this isn’t just a basic Carbon Vorsprung, as it has every single factory upgrade possible, making this one of the most loaded RS6’s on the road.

Coming in at £120,000, the Carbon Vorsprung isn’t exactly pocket change, but at a cool £60k less than the GT, it does make you question whether the extra exclusivity and performance are worth the additional outlay. We put the two side by side to highlight the differences so you can decide for yourself… click here to watch the video on our Youtube channel…

We’ll start with the most obvious difference: the paint. While the Carbon Vorspung keeps it cool and classy with its uniform covering of gorgeous Grenadine Red metallic paint, the GT keeps it loud and lairy with a tri-colour design that apes the iconic racing livery of the celebrated ‘90s track machine.

While it may not be to everyone’s taste, the eye catching styling includes bonnet stripes that look black from a distance, but close up you can see they are in fact clear, and the black you are seeing is actually the weave of the carbon-fibre underneath!

This use of the lightweight exotic composite extends beyond the GT’s bonnet to include the front wings too, which had additional air vents behind the wheels to allow pressure to escape from the arches, improving aerodynamics and brake cooling. The Carbon Vorsprung has to make do with aluminium versions for both bonnet and wings, and without the extra venting too.

There’s a considerable difference in the cars’ front bumpers too. The GT has its own bespoke item that is both deeper and wider with a larger Honeycomb grille and a red striped splitter skimming the tarmac. With the inner parts of the bumper also painted gloss black, it gives the impression of a seriously wide open-mouth intake, which is extremely aggressive. The one area where the Carbon Vorsprung trumps the GT at the front end is with the discreet fitment of its excellent night vision camera, which is located inside the right hand ring of the Audi badge. The GT does not come with this as an option.

Moving back from the front bumper and under those vented arches, the GT has a set of unique six-spoke wheels that are a retro design that harks back to models from the ‘80s and ‘90s. But while the spokes may be chunky, their forged aluminium construction means they remain super lightweight. The Carbon Vorsprung uses the more common split five-spoke rims, while both cars run Audi’s incredible carbon ceramic brakes behind them. These super stoppers come as standard on the GT and are a £10,000 option on the standard RS6.

Up top, to keep the car’s centre of gravity as low as possible, the GT has a lightweight aluminium roof with no roof rails or sunroof. This is in contrast to the Carbon Vorsprung which has both roof rails and a full panoramic roof, which while adding considerable weight to the highest part of the car, does provide a gloriously airy feel to the cabin and allows an unobstructed view of the sky and the burble from the meaty exhaust system. The glass roof is an option on RS6 GTs in Australia, (along with a host of other tasty upgrades that they get Down Under) but not in the UK.

Both cars have the same carbon-fibre clad mirrors, while the doors, rear quarters and side skirts are also identical – it’s at the rear of the car where the differences once again become more obvious.

Immediately noticeable is the large dual-element rear roof spoiler inspired by 2020’s RS6 GTO concept. Accompanied by a gurney flap to the rear bumper and a completely redesigned diffuser offering greater functionality, these aerodynamic upgrades increase downforce, helping to keep the rear of the car planted at speed. The final touch being the  bespoke GT badging, to complete the more menacing look to the rear end.

That about wraps up the exterior differences, so before we get into the performance upgrades, let’s take a peek into each car’s interior.

For starters, the Carbon Vorsprung has an opulent leather clad interior, with red stitching  and carbon fibre inlays to the dash and door cards. This contrasts with the GT’s more motorsport-inspired design which features swathes of tactile alcantara. (Again, the Aussies get the option to add carbon inlays to their GTs, but this is not an option in the UK) This suede-like material covers everything from the dashboard to the door cards, pillars and headlining, with the bespoke carbon-backed bucket seats also getting in on the action, topped off with red and bronze stitching.

The front seats themselves differ too, not just in their choice of trim, but in their design and functionality, the GT coming with deeper bolsters and manual adjustment to minimise weight, while the Carbon Vorsprung has fully electric, full leather sports seats with both cooling and heating functions. The rear bench seats are the same, except for the different trim materials and stitching colours which match their respective fronts.

Both cars have the same centre consoles and multi-function steering wheels, with only the addition of a unique numbered build plate between the arm rest and centre console and bronze stitching to accompany the red thread on the GT.

The floor mats are bespoke to the GT with RS6 GT badging stitched in red, while the puddle lights and stainless steel sills also display RS6 GT logos.

The GT’s motorsport theme continues with the dash clocks, which are stark white on the GT while the car’s multifunction LCD display can be set to show a graphic of the car in its full livery. Tech wise, both cars are very similar with only the omission of soft-close doors on UK examples of the GT, again most likely to reduce any unnecessary weight.

The final visual difference between the models is the additional of red seat belts in the GT compared to more subtle black with red pin stripe items in the Carbon Vorsprung.

Considering both models use the same 4.0-litre twin turbocharged V8 delivering 621bhp – albeit with meatier OPF-back exhaust and a slight remap to the ECU in the GT to sharpen throttle response and increase midrange punch – it’s remarkable how differently they drive. The GT is a much more focused, more raw machine that shrinks around you when on the move and feels like a much smaller car due to its nimble handling and razor sharp responses.

Much of this is down to the car’s reduced mass, a byproduct of the use of lightweight parts and a lack of panoramic roof, but can also be attributed to the car’s uprated suspension and running gear.

The GT uses bespoke coilovers with three-way adjustment for height, compression and rebound that have been tuned to offer a more sporty ride and increased precision in the steering and handling. Combined with a rear differential reconfigured to send a greater percentage of the torque to the rear wheels, and the GT feels like a completely different animal to the Carbon Vorsprung, with more punch, faster, rifle bolt gearchanges and a more racey feel to the steering and ride.

So there you have it. A comprehensive run down of all of the differences between the RS6 GT and a fully loaded RS6 Carbon Vorsprung. While its clear the GT boasts a more focused drive and a more standout aesthetic, it does come at a hefty financial cost over an already epically capable Carbon Vorsprung. Whether that cost for the rarity, brutal race-inspired looks and undiluted performance are worth it, is totally subjective and up to the individual to decide. But one thing is for sure, both of these super estates are truly groundbreaking models that redefine not just the genre, but what is even possible with a five-seat estate car.

Two truly remarkable machines, but which would you choose?
