As Volkswagen brings refreshed design, new tech, and refined dynamics to the MK8.5 GTI and Golf R, owners are already looking for ways to enhance performance beyond factory limits. At Unitronic, every product is engineered with the same guiding principles: Exceptional build quality, direct bolt-on fitment, and real-world performance gains you can feel on both the street and track. Whether you're chasing reduced intake temps, improved throttle response, improved sound, or better drivetrain stability, Unitronic's ecosystem of hardware upgrades is built to deliver improved performance with unmatched reliability.
Below is an overview of the key Unitronic product categories available for the MK8.5 platform where each upgrade is carefully designed with purpose and precision.
INTAKE UPGRADES
Factory intake systems can be restrictive, with flow paths that leave much to be desired, especially when building for more power. Unitronic Intake Systems feature smooth CFD-optimized transitions, high-flow filters, and robust construction. These attributes combine to offer reduced restriction and enhanced throttle response, allowing your turbo work more efficiently throughout the entire rev range. They’re also engineered to complement supporting upgrades like Turbo Inlets, Intercoolers and Charge Pipe Kits, ensuring a strong foundation for any power goal.

INTERCOOLER UPGRADES
Upgrading the factory intercooler is one of the most effective ways to maintain power in demanding driving scenarios. Unitronic Intercoolers use a bar-and-plate core with significantly increased volume and surface area to drastically reduce intake air temperatures, resist heat-soak, and keep the engine pulling strong, with quick recovery, run after run. Designed for stock turbo or upgraded-turbo applications, they provide consistent performance in all conditions while retaining true bolt-on fitment.

EXHAUST SYSTEM UPGRADES
Crafted from high-quality stainless steel with precise TIG welding, v-band flanges and user-selectable tips, Unitronic Exhaust Systems are built for maximum exhaust flow, refined tone and durability. Whether you're looking for a deeper, more aggressive sound or improved flow to support higher horsepower, our exhaust upgrades deliver a perfect balance of sound, drivability, and OEM-plus fitment. They enhance the driving experience without introducing drone, all while reducing backpressure for improved performance.
MK8.5 GTI Cat-Back Exhaust System
MK8.5 Golf R Cat-Back Exhaust System
The Unitronic Performance Downpipe for the 2.0TSI EVO4 platform features a high-quality, emissions-friendly 5" GESI UHO catalyst with CFD-optimized cast uppers for maximum performance and heat resistance. Combine it with Unitronic's Cat-Back Exhaust System to create a high-flowing Turbo-Back Exhaust System which helps alleviate back pressure and increase sound with premium construction, all while maintaining OEM exhaust flap functionality. (MK8.5 Golf R) With Performance Software for the new SIMOS 19.63 ECU in development, users will soon be able to upgrade to Stage 2 ECU Performance Software for the ultimate performance upgrade path.
DRIVETRAIN UPGRADES
Unitronic Dogbone Mounts help address one of this platform's common weak points for performance-oriented enthusiasts: drivetrain slop. By reducing excessive engine movement, Unitronic Dogbones help you put down the power for improved feel and traction during acceleration and gear changes. The result is a more connected driving experience with smoother power delivery and improved shifting precision, ideal for both spirited driving and track use. With two available bushings to choose from, users can also select a style which works best for their specific driving style.
