FEATURES:
• Fits all Porsche 718 Boxster/Cayman Base/S Models 2017+ and GTS Models 2017-2020 Worldwide
• Improves power, sound, and throttle response by decreasing back pressure and increasing exhaust flow
• Simple bolt-on installation. Instructions included below
• The largest HJS German imported EURO 6 homolgated tri-metallic catalytic converter that will fit in the factory location
• Designed to fit Left hand drive and Right hand drive cars worldwide
• Significant performance gains across the RPM band. Estimated +20HP gained over the factory unit
• Even more power can be unleashed with a ECU tune.
• Optimized for maximum performance with NO catalyst generated check engine light, guaranteed
• Superior quality all German and USA components built in house by hand
• TIG welded by our expert welders3 inch 76mm tubing for maximum flow into Dual 2 inch T304L stainless steel construction
• Fabspeed performance products are backed by Fabspeed's Lifetime Warranty
PURCHASE DISCLAIMER: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.
The Fabspeed Sport Cat with Downpipe is a great bolt-on modification for any 718 Turbo car. These Sport Cat with Downpipes feature German made HJS 200 cell EURO 6 EC certified compliant trimetallic catalytic converters. We use all mandrel bent T304L stainless steel 3 inch tubing that splits into 2 inch tubing from the cat to the rest of the exhaust. The cats are the largest and highest flowing catalytic converters you can fit on the 718. Larger catalytic converters are better because they allow for more exhaust flow and the increased catalysts surface area allows for better exhaust gas filtering which means emissions compliance and will NOT trigger a check engine light. Our Sport Cat Downpipes are a direct bolt-on replacement for the factory 718 catalytic converter and downpipe.
SOUND:
The Sport Cat with Downpipe adds more volume to the characteristic boxer engine rumble. No droning, and the activation of Sport mode greatly increases cracks and pops during shifting and overrun conditions. Expect a slight increase in turbo sound as well - which can be enhanced even further at any point with the separate addition of our Maxflo Exhaust System.
POWER:
Fabspeed's Sport Cat with Downpipe will add an estimated 20 whp. You can extract even more power with our hardware in conjunction with a Fabspeed ECU Tune.
FINISH:
T304L stainless steel, beautifully welded together and finished off with hand made single-wall stainless steel tips or premium matte carbon fiber shrouded tips.
Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.

- The Exhaust Sport Downpipe with Cat Bypass is a performance upgrade specifically designed for Porsche 718 Cayman and Boxster models.
- This downpipe replaces the stock catalytic converter with a bypass, allowing for improved exhaust flow and reduced backpressure.
- By eliminating the catalytic converter, the downpipe increases horsepower and torque, resulting in enhanced performance.
- The bypass also alters the exhaust note, providing a deeper and more aggressive sound for a sportier driving experience.
- It is important to consider local regulations and laws regarding emissions before purchasing and installing this upgrade, as it may not be legal for road use in some jurisdictions.

Exhaust Catalytic Converters & Bypass Pipes – Performance, Efficiency & Flow Control
The catalytic converter plays a crucial role in your Porsche’s exhaust system, reducing harmful emissions while maintaining optimal exhaust flow. Positioned between the exhaust manifold and silencer, it converts toxic gases such as carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful emissions before they exit the tailpipe.
At Design911, we offer a complete range of catalytic converters and bypass pipes for Porsche vehicles. Our manufacturer-quality converters ensure reliable emission control and long-term performance, while our bypass options are designed for track or performance use, optimising exhaust flow for maximum power and throttle response.
Whether you’re maintaining your Porsche to meet emissions standards or upgrading for improved exhaust performance, our selection includes both direct-fit converters and performance bypass kits built from high-grade stainless steel for strength, corrosion resistance, and durability.
What Do Catalytic Converters & Bypass Pipes Do?
A catalytic converter uses a fine mesh of precious metals to trigger chemical reactions that break down pollutants. The bypass alternative eliminates restriction in the exhaust flow, improving performance in non-emissions-controlled environments such as track driving.
Core Functions:
- Converts
toxic exhaust gases into environmentally friendly emissions.
- Maintains
exhaust back pressure for engine efficiency.
- Reduces harmful NOx, CO, and HC emissions.
- Supports smoother engine performance and throttle control.
- Bypass versions enhance exhaust flow and improve power output for track cars.
Upgrading to a performance-grade system ensures your Porsche continues to meet emission requirements — or achieves greater flow and responsiveness for motorsport applications.
Why Do Catalytic Converters Fail?
Catalytic converters are exposed to extreme heat, unburnt fuel, and contaminants — all of which can degrade their performance over time.
Common Causes of Failure Include:
- Carbon
or oil buildup blocking the internal honeycomb.
- Thermal
damage from overheating or rich fuel mixtures.
- Physical
damage from road debris or misfiring engines.
- Corrosion
due to moisture and exhaust condensation.
- Age-related wear reducing catalytic efficiency.
A failing converter can cause reduced engine power, poor
fuel economy, rattling sounds, or a check-engine light. Replacing it
restores emissions compliance, performance, and exhaust efficiency.
Why Replace or Upgrade
with Precision-Engineered Components?
Replacing a failing converter or upgrading to a bypass pipe ensures your Porsche maintains peak performance and reliability.
Key Benefits:
- Restores optimal emissions performance and efficiency.
- Improves exhaust flow and throttle response.
- Reduces engine stress and fuel consumption.
- Durable stainless-steel construction for longevity.
- Direct-fit
compatibility for Porsche 911, Cayman, Boxster, Panamera, Macan
and more.
- Performance bypass options available for track and tuning applications.
Whether you want emissions compliance or maximum flow for competition use, our parts deliver reliability, precision, and performance.
Highlights:
- Direct-fit catalytic converters and bypass pipes for Porsche models.
- Precision-engineered for optimal flow and reduced emissions.
- Built from heat-resistant stainless steel for durability.
- Bypass pipes for performance tuning and track applications.
- Restores power, efficiency, and exhaust sound balance.
- Available for classic and modern Porsche vehicles.
