Popular Porsche 911 991 Upgrades
The Porsche 911 991 is a seriously special bit of kit, sitting in that sweet spot between classic 911 feel and modern engineering. As the seventh-generation 911, it brought sharper handling, clever electronics and real everyday usability without losing that trademark rear-engined character. Whether you are in a Carrera, Turbo, GTS or GT3, the 991 platform responds brilliantly to intelligent tuning. From exhaust and intake upgrades to suspension and brake mods, it is a favourite in club motorsport, track days and fast road builds alike.
The usual first mods on a Porsche 911 991 are breathing and mapping upgrades. Owners often start with a performance panel filter or upgraded intake, a sports exhaust or backbox, and an ECU remap to bring it all together. Those simple tuning parts give sharper throttle response, a stronger mid‑range, and far better sound without making the car awkward to live with day to day. From there, the tuning journey can get a bit more serious. On turbo models, uprated intercoolers, turbochargers and high‑flow downpipes help control temps and release extra, reliable horsepower and torque. Pair that with improved cooling, maybe a mild fuel system upgrade, and you have a very capable fast‑road or track 991. Many enthusiasts then round things off with suspension upgrades, geometry tweaks and stickier tyres to match the extra power with proper handling and braking performance.
Top Brands For Porsche 911 991 Mods And Upgrades
For the Porsche 911 991 you are spoilt for choice when it comes to aftermarket performance parts. Below you will find leading brands known for quality tuning, motorsport upgrades and precision engineered components to take your 991 to the next level on road or track.
Porsche 911 991 Exterior Styling Upgrades
The Porsche 911 991 looks special from factory, but with the right exterior styling mods you can really sharpen its presence. From subtle splitters, diffusers and custom grilles to full body kits, spoilers and aero packs, you can dial in a more aggressive, track-inspired or totally unique look to suit your build.
Porsche 911 991 Suspension & Handling Upgrades
The Porsche 911 991 is already sharp, but there is plenty of room to tighten up agility and feedback. Start with tyres and brakes, as good rubber and performance brake pads give an immediate boost in grip, stability and confidence. A stickier road or track-focused tyre, matched with uprated pads and fluid, helps control the 991’s rear-engined balance and reduces fade on fast B-roads or circuit sessions. If you are pushing harder, a big brake kit will add consistency and better pedal feel without needing massive power gains. From there, look at suspension tuning. Quality lowering springs or coilovers bring the centre of gravity down and calm body roll, without ruining road manners if you choose sensible spring rates. The 991 can feel a touch soft and safe at the limit, so uprated dampers, stiffer anti-roll bars, and fresh bushings make turn-in crisper and mid-corner balance more neutral. Add a strut brace to sharpen steering feedback and you end up with a Porsche 911 991 that feels more planted, responsive and genuinely more fun in every corner.
Porsche 911 991 Frequently Asked Questions
What are the best first performance upgrades for a Porsche 911 991?
For most 911 991 models, a sensible starting point is breathing and software. A freer flowing panel filter or intake kit, a high quality cat-back exhaust and a properly calibrated ECU remap will usually give noticeable gains in power and torque, sharper throttle response and a more involving sound without making the car awkward to live with.
On turbocharged 991.1 and 991.2 models, these simple mods can unlock a decent chunk of extra performance, especially when paired with uprated intercoolers. On naturally aspirated Carreras, you will see smaller peak figures, but the car will feel more responsive and eager across the rev range.
How much power can I safely gain from a remap on my 991?
On 991 Turbo and Carrera T / GTS turbo models, a well developed ECU tune with supporting mods, such as an upgraded intake and exhaust, can deliver a healthy increase in horsepower and torque while staying within the safe limits of the stock engine and drivetrain. Think in terms of a strong but sensible bump, not a wild race map.
On naturally aspirated Carreras, a remap is more about sharpening the delivery and improving drivability. You may see a modest increase in peak power, but the main benefit is improved mid‑range torque, better throttle response and smoother power delivery.
Whatever the model, it is crucial to use quality software from a reputable tuner, and to keep the car well maintained with regular servicing and good fuel.
Will tuning my Porsche 911 991 affect reliability?
If you stick to proven performance parts and a conservative tune, a lightly modified 991 can remain very reliable. Upgrades like an intake, cat-back exhaust, sport cats and a sensible ECU map are generally well within what the standard engine, gearbox and cooling system can handle for fast road use.
Reliability issues tend to appear when power is pushed too far without the correct supporting mods, for example running very high boost on a turbo car without improved cooling, fuelling or proper heat management. We always recommend planning a balanced upgrade package rather than chasing the biggest dyno figure.
Regular oil changes, using the correct grade, sticking with quality tyres and keeping on top of brakes and suspension wear become even more important as you tune the car.
What supporting mods should I consider for a tuned 991?
Once you increase power, it makes sense to look at handling and stopping power. Uprated brake pads, performance discs and stainless braided lines give you more consistent braking on fast road or track days. Quality coilovers or sport springs and dampers will tighten up the chassis and let you actually use the extra performance.
On turbocharged 991s, uprated intercoolers, a better exhaust with sport cats and improved intake hardware help control temperatures and back pressure, which keeps the tune safe and repeatable. For harder track use, you may also want upgraded engine and gearbox mounts plus better cooling for the PDK where applicable.
What wheel and tyre sizes work well on the Porsche 911 991?
The 991 platform responds really well to lightweight performance wheels and quality tyres. Many owners stick close to OEM sizing, for example 20 inch rims with a slightly wider tyre, to keep the balance of grip, comfort and steering feel. Going too wide for the sake of looks can spoil the handling and cause rubbing on arches or liners.
If you are changing alloys, pay close attention to offset and width. The 911 is sensitive to geometry, so using sensible offsets and matching them with an appropriate ride height is key. A proper alignment after fitting new wheels or suspension upgrades will make a huge difference to how the car feels.
Is an aftermarket exhaust worth it on a 991?
Yes, a quality performance exhaust is one of the most popular mods for the Porsche 911 991. A cat-back system or rear silencer upgrade can unlock a more aggressive sound, reduce weight and, when combined with a remap and intake, support small but useful performance gains.
Switchable valved exhausts mean you can keep things civil on cold starts and motorways, then open it up when you want the full sports car noise. Just be realistic about volume and make sure any system you choose is compatible with UK MOT and emissions rules, especially if you are changing cats.
How much does it roughly cost to tune a 911 991?
Costs vary a lot depending on how far you want to go. A basic stage 1 style package, intake, cat-back exhaust and ECU remap, will usually sit in the lower thousands once you include fitting and mapping. This gives a noticeable uplift in performance for fast road driving without major changes to the car.
Going further with uprated turbos, intercoolers, suspension kits and big brake upgrades can quickly climb into more serious money, especially if you are building a track focused 991. The best approach is to set a realistic budget, decide on the use of the car, road, track or mixed, and then plan a staged tuning path rather than buying parts at random.

Final Thoughts on the Porsche 911 991
The Porsche 911 991 is already a superb bit of kit from the factory, with a strong engine range, sharp steering and that classic rear-engined feel that enthusiasts love. Its balance of everyday refinement and weekend fun is one of its biggest strengths, especially in Carrera and Turbo form. At the same time, most owners quickly notice where Porsche has left a bit of safe margin, whether that is slightly soft road-biased suspension on non-GT models or quieter than ideal exhaust systems that hide some of the flat-six character. This is where the right performance mods and tuning parts really wake the car up. A quality exhaust and intake, paired with sensible ECU software, can bring sharper throttle response and more mid-range torque without hurting reliability. On turbocharged 991s, better intercoolers and improved heat management help keep intake temps in check on spirited drives and track days, so the car feels more consistent lap after lap. Many enthusiasts also look at uprated clutches or PDK software tweaks to handle extra torque with confidence. Handling and chassis upgrades are equally rewarding on the 911 991. Uprated coilovers, springs and anti-roll bars can trim the roll and nose dive you get on fast B-road runs, while still keeping enough compliance for daily use if set up correctly. Performance brake pads, braided lines and better fluid cure the slightly soft pedal feel you can get when the car is pushed hard. Combine this with a proper geometry setup and you end up with a 911 that feels tighter, more precise and easier to trust on the limit. Finally, styling tweaks and motorsport-inspired accessories let you make your Porsche 911 991 feel genuinely your own. Lightweight wheels, subtle aero upgrades and interior touches like bucket seats or a smaller steering wheel can all add to the sense of occasion every time you drive. With a carefully chosen mix of performance parts, handling upgrades and cosmetic mods, the 991 can be turned into a car that fits your driving style perfectly, without losing the everyday usability that makes it so special. Treat it as a platform to fine-tune rather than fix, and you will end up with a 911 that feels properly sorted every time you turn the key.
