Performance Parts for the Porsche 991 GT3 / GT3 RS

Is your 991 GT3 living up to its true potential? Our performance exhaust, tuning, and custom aftermarket innovations are paving the way to first place. Tailored to overcome stock inefficiencies, our street, and competition-ready 991 GT3 components open up the possibilities for your soon-to-be optimized sports car.

How can our pioneering design and fabrication experts add lasting value to your 991 GT3? Our performance parts feature state-of-the-art alloys, higher-flowing exhaust parameters, and precision-tuned CNC fitments for simple bolt-on upgrades that are guaranteed to outperform. After 30 years of exotic and sports car improvement, Fabspeed Motorsport is your single destination for:

  • Dyno-tested performance data: Our exhaust, intake, exterior mods, and brake components are founded on rigorous performance testing for data-driven upgrades that perform better than expected.
  • Industry-leading material quality: Superb, CNC-cut materials like T304L stainless steel can withstand the most intensive racing conditions without failure. In fact, unlike the 991 GT3 OEM muffler, which is prone to breakage, our proven designs, such as our Porsche 991 GT3 / GT3 RS Rennsport Muffler, are engineered to last a lifetime.
  • Sleek and functional exterior enhancements: Sophisticated and contemporary, our versatile carbon fiber parts have redefined lightweight sports vehicle excellence. Choose from smart upgrades like our carbon fiber exhaust tips and custom mirror covers, or streamline your aerodynamic body lines with a pair of our luxurious anti-wind buffeters or rear spoiler end caps.

Upgrade Your Porsche 991 Exhaust System

Our most popular upgrades for a good reason: we transform street and racing platforms with versatile GT3 and Porsche GT4 exhaust systems that boost power, reduce backpressure, and unleash sporty exhaust tones. From long-tube headers to our revolutionary X-pipe and Maxflo mufflers, your Porsche gains the competitive edge with any of our free-flowing systems installed.

For stock 991 GT3s, we highly recommend a comprehensive exhaust overhaul that includes new headers, side muffler pipes, deluxe exhaust tips, an air box filter, and a premier tuning package. Our complete upgrades overcome stock muffler frailty, amplify the exotic sports tone, and provide substantial power gains and heightened responsiveness throughout the RPM range.

Alternatively, investing in part-by-part exhaust replacements is a great way to achieve finely tuned performance updates. To activate a sportier exhaust sound, opt for a capable set of our sport headers or turn heads with our highly popular Maxflo performance system. Other often overlooked upgrades, such as upgrading to a higher-flowing filter like our BMC F1 Replacement Air Filter, promote optimal combustion and cleaner engine performance. Best of all, our high-performance filters can be cleaned/re-oiled again and again for lasting performance and low-cost engine component preservation.

High-Performance Brake Systems

No Porsche masterpiece is complete without a superior brake system installed. We exclusively offer rotors from Girodisc; these capable, aircraft-grade aluminum upgrades are ready for the track immediately after installation. Our preferred rotors are exceptionally heat and wear-resistant while simultaneously being a significantly more affordable option than costly ceramic alternatives. Expect reliable bite, longer-lasting brake performance, and long-term savings so you can spend your Porsche budget on an exhaust or tuning upgrade instead!

Tips for Maintaining Your Porsche 991 Parts

Preserve the value of your GT3 and Porsche Boxster upgrade by keeping all high-performance parts clean and well-maintained. Each time you perform an oil change, inspect the exhaust, intake, and any other additional modifications for signs of corrosion, impact damage, or dirty accumulation. Be sure to inspect mounts, brackets, and connections for separation, leaks, or any other unusual issues that may indicate a need for repair.

When cleaning your components, be sure to use approved cleansers designated for that specific material type. For example, when cleaning carbon fiber exterior components, never use harsh chemicals or abrasive materials that could tarnish or scratch the polished finish. Opt for mild, material-specific cleansers and apply them with a soft cloth or sponge to avoid any potential surface damage. The same goes for air filter cleaning; use our approved filter cleaning kit and follow the instructions carefully to avoid damaging the sensitive filter materials.

What is the best way to protect your valuable components? Partner with our experts at Fabspeed Motorsport to handle the installation and learn how to maintain your parts like an expert. We are dedicated to factual customer education, offering personalized build consultations and in-depth support for all stages of Porsche improvement. For part recommendations and component care advice, contact our friendly exotic car experts for a free consultation today!
