DesignTek Performance Parts for Porsche
DESIGNTEK — PERFORMANCE ENGINEERED
Porsche performance upgrades for road, fast road and track. Explore DesignTek exhaust, suspension, braking, induction, wheel fitment, chassis and driver-focused upgrades for classic and modern Porsche models.
Better sound. Better stance. Better response. Better control.
The DesignTek story
DesignTek is Design911’s Porsche-focused performance brand, created for drivers who want to get more from their car. Its products are selected and developed to enhance the driving experience, whether through a sharper exhaust note, shorter gearshift, more controlled suspension or a purposeful change in stance. With around 500 products, the range has grown to cover straightforward fast-road upgrades alongside more focused track and motorsport components for classic and modern Porsche models.
Why choose DesignTek for your Porsche
DesignTek occupies the quality aftermarket and performance-upgrade tier, providing Porsche-specific alternatives when an owner or workshop wants to go beyond a standard replacement component. The range supports different objectives, from restoring clean airflow and improving driver feel to developing a more focused road, track or competition car. DesignTek is not about modifying a Porsche simply for the sake of it; it is about choosing considered upgrades for the way the car will be driven. Design911 specialists can help customers compare applications, specifications and related components before selecting an upgrade.
- Porsche-focused applications rather than a predominantly universal range
- Exhaust, suspension, braking, induction, chassis, wheel-fitment and driver upgrades
- Coverage extending from classic air-cooled 911 models to modern Porsche applications
- Options for road, fast-road, track and competition use
- Direct-fit and adjustable products where specified for the application
- An accessible route from standard replacement parts to more specialised performance equipment
DesignTek performance ranges
The Design911 DesignTek range covers the principal areas used to change how a Porsche sounds, sits, responds and feels. Always confirm the listed model, year, position, OE reference, connector type and included fittings before ordering.
Performance Exhaust Exhaust is at the heart of the DesignTek range, with individual components and complete performance systems for classic and modern Porsche models.
- Valvetronic switchable systems, sports silencers, rear boxes, manifolds, headers, downpipes, sports catalytic converters and catalyst-bypass or decat pipes
- Classic 911 heat exchangers, stainless-steel systems and carbon-fibre or performance exhaust tips
- Selected listings specify SUS304 or T304 stainless steel, high-flow 200-CPSI or 300-CPSI catalysts, switchable valves and carbon-fibre tailpipes
- Options address exhaust character, flow, appearance and complete system upgrades; catalyst-bypass products are intended for appropriate track-focused applications
Performance Suspension DesignTek suspension products are intended to strengthen the connection between the driver, chassis and road, with choices spanning road use to competition.
- DesignTek Performance Springs, lowering spring kits, adjustable ride-height suspension and D220 coilover systems
- Selected D220 applications include adjustable damping, while the specialist Asphalt Rally range provides greater adjustment for competition use
- Road-focused springs provide a lower stance and increased control where specified
- Inspect worn mounts, bushes and adjacent components, and complete the required alignment and torque procedures after installation
Performance Braking DesignTek braking products support Porsche builds requiring replacement components or a more substantial braking upgrade.
- Carbon-ceramic replacement brake discs and compatible brake pads for specified Porsche applications originally equipped with ceramic systems
- Performance brake components, GT-style packages, Big Red kits and larger upgrades for selected classic and modern Porsche platforms
- Check disc size, caliper type, wheel clearance and the complete application before selecting an upgrade
Performance Airflow & Induction DesignTek airflow products range from direct-replacement filters to complete intake systems and supporting components.
- Cold-air induction kits, high-flow intake systems, intake hoses, selected plenums and associated airflow upgrades
- Dedicated induction products are offered for selected Boxster and Cayman applications, alongside systems for other Porsche generations
- Maintain proper sealing, sensor positioning and sensible intake temperatures to avoid unmetered air, poor idle, warning lights, heat soak or inconsistent response
- Check mounting security and routing after installation to minimise rattles, hot-air ingestion and water exposure
Performance Air Filters DesignTek offers replacement and performance air filters for routine servicing, fast-road use and wider tuning packages.
- Applications include classic 911, 996, 997, 991 and 992 models, with further coverage across the Porsche range
- Selected filters use washable, reusable cotton-gauze media designed to balance filtration with increased airflow
- Clean the airbox and make sure the filter seal is seated evenly; a poor seal can allow dust and debris into the intake
- Replace filters more frequently in dusty or harsh conditions and avoid over-oiling reusable filters where airflow sensors are fitted
Wheel Fitment & Stance DesignTek wheel-fitment products allow owners to refine wheel position and stance, particularly alongside lowering springs or other suspension changes.
- Hub-centric wheel spacers, spacer kits, Black Edition spacers, wheel bolts, extended bolts and fitting hardware
- Selected hub-centric spacers use anodised 6061-T6 aluminium construction
- Confirm spacer thickness, wheel and tyre clearance, bolt or stud length and the specified tightening procedure
Chassis & Handling Chassis reinforcement can complement upgraded suspension, tyres and brakes by creating a more focused connection between the car and driver.
- Front and rear strut braces in selected alloy and carbon-fibre designs
- Applications include classic 911, 964, 993, 996, 997, Boxster and Cayman models
- Supporting chassis and suspension upgrades should be chosen as part of a balanced package for the intended road or track use
Driver & Track Driver-focused products change the points of interaction used every time the Porsche is driven.
- Short-shift kits, performance gearshift components, alloy pedal and footrest kits, motorsport harnesses and selected competition equipment
- Short-throw shifters are offered for selected 986, 987, 996 and 997 applications
- The range includes a six-point FIA-approved race and rally harness option
- Confirm installation requirements and compatibility with seats, mounting points and other safety equipment
Engine Tuning DesignTek engine-tuning components support improved drivability, throttle response and power delivery, or complement compatible intake, exhaust and airflow changes.
- Resolve mechanical faults before tuning rather than masking hesitation, flat spots, rough running, warning lights or inconsistent boost with new hardware or calibration
- Check compression, fuel delivery, sensor data, oil and coolant temperatures, and boost or vacuum leaks before tuning work
- Review supporting hardware and use a calibration appropriate to the complete engine specification
Performance Service Parts DesignTek service products support scheduled maintenance and can combine routine replacement work with selected performance-filter options.
- Use the correct specifications for filters, plugs, fluids, belts and related service components, and keep a clear replacement record
- Shorten service intervals where a Porsche is regularly used for short journeys, in harsh conditions or under sustained hard use
- Investigate leaks, knocks, worn mounts, poor ride control, restricted intake noise, intermittent operation, reduced fuel economy and warning lights rather than replacing unrelated parts
- Inspect adjacent components and confirm whether seals, fittings and hardware are included to reduce repeat labour
Explore the DesignTek range
Choose how you want your Porsche to feel: more sound, a lower and more purposeful stance, sharper handling, greater confidence under braking, cleaner airflow or a more involving connection between driver and car. Browse the full DesignTek range at Design911, select your Porsche model and compare compatible products with support from people who know these cars. Design911 offers worldwide delivery across one of the largest selections of Porsche parts.
The DesignTek Sports Catalytic Converter Section is a premium performance exhaust upgrade engineered for the Porsche Cayenne V6 3.0L Hybrid (2019 onwards). Manufactured from high-grade T304 stainless steel, this catalytic converter section features a 300-cell high-flow catalyst with a Euro 4 catalytic coating, providing significantly improved exhaust flow compared with the restrictive factory catalytic converter while maintaining effective exhaust gas treatment. High-flow catalyst designs reduce exhaust backpressure, allowing exhaust gases to exit the engine more efficiently and supporting improved engine response.
Fits:
Porsche 9YA Cayenne V6 3.0L Hybrid 2019 - 2023
Porsche 9YA.2 Cayenne V6 3.0L Hybrid 2023 >>
Key Features & Benefits
• Premium DesignTek performance exhaust component
• 300-cell high-flow catalytic converter
• Euro 4 catalytic coating
• Manufactured from T304 stainless steel
• Heat-resistant shield wrap for improved thermal management
• Improved exhaust flow and reduced backpressure
• Supports improved throttle response and engine efficiency
• Corrosion-resistant construction for long service life
• Direct-fit installation
To improve durability and thermal management, the catalytic converter section is wrapped in a heat-resistant thermal shield. This insulation helps retain exhaust gas temperature inside the catalyst for efficient operation while reducing radiant heat transferred to surrounding engine bay and underbody components. Heat shielding also protects nearby hoses, wiring, and other sensitive parts from excessive temperatures.
Designed as a direct-fit replacement for the factory catalytic converter section, this DesignTek component is precision manufactured for excellent fitment and long-term corrosion resistance. The combination of stainless steel construction, high-flow catalyst technology, and thermal shielding makes it an excellent choice for enthusiasts seeking improved exhaust efficiency, enhanced throttle response, and a sportier exhaust note without compromising build quality.
Please note: These sport cats will make your car sound louder than with stock cats. If you have, or intend to install sport silencers, you may find the car is a bit loo loud. We recommend to use one sport exhaust component if you are concerned about decibel levels.
NOTE:
In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.
For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.
If you are located outside the UK, please check your local laws and regulations to ensure compliance.

The DesignTek stainless steel exhaust heat exchangers are a high-quality aftermarket upgrade designed for the Porsche 911 2.7L / 3.0L Carrera (1974–1983). Combining exhaust flow efficiency with integrated cabin heating functionality, these units provide a reliable and performance-oriented replacement for original factory heat exchangers.

- Porsche 911 1978-1983 3.0L
Heat exchangers play a dual role in classic Porsche engines - they channel exhaust gases away from the engine while transferring heat to the cabin heating system. Over time, original units can corrode or crack due to constant heat cycles and exposure to road conditions, leading to reduced heating performance, exhaust leaks, and potential safety concerns.
Manufactured from durable stainless steel, these DesignTek heat exchangers offer improved resistance to corrosion and long-term durability compared to older mild steel designs. The optimised internal pipework supports better exhaust gas flow, which can contribute to improved engine efficiency and a more responsive driving experience. High-quality materials also help withstand extreme temperatures and vibrations typical of air-cooled flat-six engines.
Designed as a direct-fit replacement, these heat exchangers integrate with standard exhaust systems and heating components, making them suitable for both restoration projects and performance upgrades. Ideal for maintaining originality while benefiting from modern materials, they deliver a balance of reliability, performance, and classic Porsche functionality.

The DesignTek stainless steel exhaust cross over pipe is a high-quality aftermarket component designed for classic Porsche 911 models from 1975 to 1989. Engineered to improve exhaust system efficiency and durability, this cross over pipe is an ideal replacement for worn or corroded original units.
Fits:
Porsche 911 1974 - 1989
Porsche 930 Turbo
The cross over pipe plays a crucial role in the exhaust system by connecting the exhaust flow between both sides of the engine. By equalising exhaust gas pressure between the banks, it helps improve exhaust scavenging, reduce backpressure, and refine overall exhaust flow. This results in smoother engine operation, improved efficiency, and a more balanced exhaust tone.
Manufactured from high-grade stainless steel, this DesignTek pipe offers superior resistance to corrosion and heat compared to original mild steel components. It is built to withstand the extreme temperatures and conditions of air-cooled engines, ensuring long service life and reliable performance.
Designed as a direct-fit replacement, this cross over pipe integrates seamlessly with existing heat exchangers, silencers, or catalytic converter systems, making it suitable for restoration projects, maintenance, or performance upgrades. It is commonly used on both naturally aspirated 911 models and compatible 930 Turbo applications.
